<u style="single">Cross-reference of related applications</u> This application is entitled "Fuel Level Sensor Assembly Attachment for Fuel Delivery Module", submitted on October 14, 2005, with serial number 60 / 727,150. Claim the priority of the US provisional application.
<u style="single">Background of the invention</u><u style="single">Field of invention</u> The invention generally relates to a fuel supply system for an internal combustion engine, and more particularly to a fuel supply module immersed in a tank containing liquid fuel and fitted with a fuel level transmission unit.
<u style="single">Related technology</u> A typical automobile fuel system includes a fuel supply module mounted in a tank that houses a cup-shaped storage tank for storing a limited amount of fuel in the tank. The fuel pump inside the storage tank takes out fuel from the storage tank and supplies it to the internal combustion engine. The fuel in the storage tank is constantly replenished by the amount of fuel around it in the fuel tank. However, as the fuel level in the tank drops, a limited amount of fuel in the storage tank provides a fuel buffer around the fuel pump. When a vehicle turns a steep steering wheel or drives a steep slope with low fuel, the storage tank helps ensure that the pump has the right amount of fuel available.
Typically, the fuel supply module also includes a steam exhaust valve and / or recirculation system, as well as a fuel level sensing float and associated electronics. The reservoir is therefore, as a container around the fuel pump for collecting reserve fuel supplies for the pump to use in situations where it might otherwise be temporarily out of fuel, as well as level sensing. Acts as a support enclosure for electronics and hardware.
The fuel supply module has the ability to detect and measure the fuel level in the fuel tank by its own fuel level transmission unit. The fuel level transmission unit is typically mounted in a storage tank and includes a float mechanism. The float mechanism is swivelly mounted on the fuel level transmission assembly, which interacts with the circuit configuration to measure the fuel level in the tank based on the floating position of the float.
The method of mounting the fuel level transmission unit in the storage tank has been of great interest for many years. For storage tank enclosures made of injection molded plastic, it is common to mold an auto-locking type of fixture in place and snap the fuel level transmit carrier in place. The carrier has a card-like mounting structure on which a float mechanism is rotatably supported. However, the problem with snap fastening techniques is that they are generally limited to applications using plastic injection molded storage tanks. Injection molding is a fairly expensive manufacturing form because the installation cost of production equipment is high and the processing speed is relatively slow. A further disadvantage is that the orientation of the fuel level transmitter to the storage tank is fixed in a single way. That is, once the carrier is snapped in place, it cannot be moved or rearranged with respect to the storage tank. This, in turn, can affect the measurement quality of the fuel supply module, depending on the particular fuel tank in which the fuel supply module is installed and the current model changes that can be introduced in the fuel tank or module mounting configuration. ..
Some fuel supply module applications require the storage tank to be made of aluminum or other metal-based material. For mounting the fuel level transmitter unit in a non-plastic enclosure, such as aluminum, the options available are limited given certain practical considerations such as manufacturing costs and the nature of the storage tank material. Some applications of the prior art teach how to resistance weld a metal frame to an aluminum storage tank. Therefore, the frame will be equipped with a carrier for the fuel level transmitter. This technique allows some variation in positioning the carrier on the module reservoir, but welding to aluminum is highly process sensitive due to the conductivity and potential oxidation of the aluminum. Therefore, it turned out that there was actually a problem. Welding-specific process variation characteristics can also be a concern.
Therefore, fuel level transmission to the storage tank of the fuel supply module, which allows variations in the positioning of the transmission unit with respect to the module storage and is achievable for any type of housing composition, aluminum, plastic, or other material. An improved method of mounting the unit is needed.
<p><u style="single">Abstract of the invention</u> The present invention comprises a type of fuel supply module that is immersed in a tank containing liquid fuel to fuel the internal combustion engine from the tank while monitoring the amount of fuel in the tank. The module comprises a storage tank that defines a theoretical longitudinal axis. The storage tank has a peripheral side wall to isolate a limited amount of fuel in the tank. A fuel pump for forcibly moving the isolated fuel from the storage tank to the internal combustion engine is arranged in the storage tank. A fuel level transmitter is provided to measure the amount of fuel in the tank. The fuel level transmitter includes a carrier and a float arm that extends swivelly from the carrier. A longitudinally extending sliding interface is placed on the side wall of the storage tank to slidably receive and secure the carrier along the capture-type positioning path. The fuel level transmitter can be positioned indefinitely longitudinally along the sliding interface during assembly and can also be permanently fixed in the desired operating position for subsequent operational use.</p><p> The present invention overcomes the drawbacks and disadvantages found in prior art systems by means of a sliding interface formed on the side wall of the storage tank. The carrier of the fuel level transmitter is trapped in the sliding interface and slides along the sliding interface until the desired operating position is achieved. The carrier is then permanently fixed in the desired operating position for subsequent operational use by suitable anchoring techniques that may include caulking and / or welding.</p><p> The present invention also considers a fuel tank assembly for accommodating liquid fuel and supplying fuel to an internal combustion engine on demand. The assembly includes a tank for accommodating liquid fuel. The storage tank is immersed in the tank and defines a theoretical longitudinal axis. The storage tank has a peripheral side wall to isolate a limited amount of fuel in the tank. A fuel pump for forcibly moving the isolated fuel from the storage tank to the internal combustion engine is arranged in the storage tank. The fuel level transmitter measures the amount of fuel in the tank. The fuel level transmitter includes a carrier and a float arm that extends swivelly from the carrier. The improvement is characterized by a longitudinally extending sliding interface located on the side wall of the storage tank to slidably receive and secure the carrier along a capture-type positioning path. The fuel level transmitter can be positioned indefinitely longitudinally along the sliding interface during assembly and can also be permanently fixed in the desired operating position for subsequent operational use.</p><p> Further, the present invention considers a method of assembling a type of fuel supply module for supplying fuel from a tank to an internal combustion engine while monitoring the amount of fuel in the tank, which is immersed in a tank containing liquid fuel. The method defines a theoretical longitudinal axis and comprises the step of providing a reservoir with peripheral sidewalls to isolate a limited amount of fuel in the tank. The method further comprises a step of inserting a fuel pump into the storage tank and a step of attaching a fuel level transmitter to the storage tank, and the fuel level transmitter is provided to measure the amount of fuel in the tank. The method is characterized by the mounting steps described above, including the step of slidably receiving and securely fixing the fuel level transmitter along a sliding interface captured along the side wall of the storage tank. The fuel level transmitter can be positioned indefinitely longitudinally along the sliding interface during assembly and can also be permanently fixed in the desired operating position for subsequent operational use.</p><p> The present invention therefore addresses the long-standing, but unresolved need associated with mounting fuel level transmitters in the storage tanks of fuel supply modules. Whether the reservoir is of metallic or plastic composition, effective, cost-effective and versatile technology can be used to position the fuel level transmitter indefinitely with respect to the reservoir, which in turn can be used. It can be fixed in an appropriate position.</p><p> These and other features and advantages of the present invention will be more easily recognized when considered in connection with the following detailed description and accompanying drawings.</p>
<u style="single">Detailed description of preferred embodiments</u> Similar numbers throughout several figures refer to drawings showing similar or corresponding parts, and the fuel tank assembly according to the invention is indicated by 12 overall. The tank assembly 12 is of a type commonly used to contain a liquid fuel such as gasoline and to feed the fuel to an internal combustion engine (not shown) on demand. Assembly 12 includes a tank 14 with a thin hollow member, which is filled with liquid fuel through nozzle 16. The fuel pump module, indicated by 18 overall, is located in tank 14. Module 18 is of a type intended to be completely immersed in the liquid fuel of the tank 14 and, on demand, feed the fuel to the internal combustion engine under pressure. The fuel pump module 18 also monitors the amount of fuel in the tank 14 at the same time.
Module 18 includes a hanger flange 20 that sits in a complementary shaped opening at the top of the tank 14. The hanger flange 20 acts as a lid to connect the fuel pump module 18 to the tank 14 and to direct fluids such as fuel and vent gas into and out of the tank 14. The fuel discharge pipe 22 is supported on the hanger flange 20 together with the fuel return pipe 24 and the ventilation pipe 26. The electrical connector 28 acts as a connector on the hanger flange 20 for powering the fuel pump through the electrical leads 30 and to the fuel level transmitter overall represented by 32. As described in more detail below, the fuel level transmitter 32 is used as a fuel detection means for measuring the amount of fuel remaining in the tank 14.
Module 18 includes a storage tank generally represented by 34, which defines the theoretical longitudinal axis A. During operation, the longitudinal axis A may be oriented vertically, but there are also applications where a tilted orientation may be required. Although illustrated as an overall ring in the drawing, this is only one configuration, as the storage tank 34 can be of almost any alternative shape. The storage tank 34 has a peripheral side wall 36 for isolating a limited amount of fuel in the tank. In the illustrated embodiment, the side wall 36 is open at its top edge 38, but is sealed by a base 40 at its bottom edge. The fuel surrounding the storage tank 34 in the tank 14 passes through the open top end 38 to the storage tank. Easily flow into 34. Once the fuel level in the tank 14 drops below the height of the top end 38, fuel can enter the storage tank 34 through the lower side or the bottom opening 42. The lower opening 42 may be equipped with a one-way valve 44, which is exemplified as a flapper valve in FIG. The one-way valve 44 prevents the fuel isolated inside the storage tank 34 from flowing out when the peripheral fuel level in the tank 14 is below the top end 38. However, whenever the fuel around the storage tank 34 exceeds the pressure difference with the fuel inside the storage tank 34, the one-way valve 44 automatically opens and the liquid fuel from the surrounding tank 14 can flow into the storage tank 34. It becomes. In an alternative configuration (not shown), the one-way valve 44 and / or the opening 42 may be located in the side wall 36 instead of in the base 40.
The fuel pump, which is generally shown by 46 in FIG. 3, is arranged in the storage tank 34. The fuel pump 46 is provided to forcibly move the fuel isolated inside the storage tank 34 to the internal combustion engine. Any such fuel pump suitable for this purpose can be used herein. The fuel pump 46 is an electrically driven, motorized device that receives power through an electrical connector 28. The suction side of the fuel pump 46 sucks fuel into the pump 46 through the suction filter 48. Although illustrated inside the storage tank 34 in FIG. 3, the suction filter 48 may instead be placed outside the storage tank 34 facing the opening 42. The high pressure or discharge side of the pump 46 is connected to the fuel discharge pipe 22 via a flexible hose 50.
The base 40 of the storage tank 34 is equipped with a plurality of legs 52 for engaging with the bottom of the tank 14. The compression spring 54 extends so that it can operate between the hanger flange 20 and the storage tank 34, and the fuel pump module 18 is firmly placed in the operating position in the tank 14. A guide rod 56 extends through the compression spring 54 to prevent buckling and provide a rigid connection between the hanger flange 20 and the storage tank 34. The guide rod 56 slides retractably in a corresponding cradle (not shown) in the storage tank 34. Therefore, the compression spring 54 presses the leg 52 tightly against the floor of the tank 14, fixing it on the hanger flange 20 and firmly holding the fuel pump module 18 in place inside the tank 14.
As mentioned earlier, the fuel level transmitter 32 is provided to measure the amount of fuel in the tank 14. With reference to FIG. 2, the fuel level transmitter 32 is shown to include a carrier 58 and a float arm 60 that rotatably extends from the carrier 58. A sliding interface 62 extending in the longitudinal direction is arranged along the outside of the side wall 36 of the storage tank 34, and slidably receives and firmly fixes the carrier 58 along the capture-type positioning path. In other words, the sliding interface 62 establishes a controlled path along which the carrier 58 can be moved over a range of longitudinal positions with respect to the side wall 36. The fuel level transmitter 32 can be positioned indefinitely longitudinally along the sliding interface 62 during assembly and can be permanently fixed in the desired operating position for subsequent operational use.
As illustrated in the drawing, the storage tank 34 is preferably extruded from a plastic or aluminum material into an overall cylindrical tubular shape between its top end 38 and the base 40. The circular cross section of the storage tank 34 is interrupted by a pair of opposing flanges 64 separated by a gutter-shaped recess 66. The flanges 64 of this embodiment are spaced apart from each other and extend parallel to the longitudinal axis A. Each flange 64 has an outer surface 68 that is coplanar with the outer surface 68 of the opposing flange 64.
The sliding interface 62 as illustrated in the drawings merely represents a single preferred embodiment of the present invention. Those skilled in the art will recognize that other mechanical variants of the general concept can be achieved with comparable effect. For example, if the storage tank 34 is manufactured by a technique other than extrusion molding, such as injection molding, the sliding interface 62 may only partially extend along the length of the storage tank. Side wall 36 of storage tank 34 fits any specific application or manufacturing conditions Similarly, the sliding interface 62 can be significantly reconstructed from what is illustrated in the drawings without departing from the ideas of the present invention so that its shape can be changed to allow it.
Perhaps best shown in FIG. 2, a pair of positioned recesses 70 are introduced into the flange 64 so that the small portion of the flange 64 deforms inward towards the gutter 66. If the side wall 36 is made of extruded aluminum or other malleable material, the recess 70 is preferably formed by tightening or punching operations. However, if the side wall 36 is made of plastic or other thermally sensitive material, the recess 70 can be made by heat caulking. Of course, other techniques for introducing the recess 70 into the flange 64 are also possible.
With reference to the fuel level transmitter 32 as illustrated in FIGS. 1 and 3, the carrier 58 is adapted to fit into the sliding interface 62 by interacting with the flange 64. The gutter 66 establishes a sliding gap with respect to the side wall 36. The float arm 60 extends swivelly from the carrier 58 and supports the floating float 72 at its far end. The electronic circuit configuration built into the carrier 58 interacts with the float arm 60 to record the relative swivel movement due to the occasional position of the float 72. The electronic circuit configuration is preferably integrated into the body of the carrier 58. In a preferred embodiment, a swivel bearing 74 for the float arm 60 is established within the carrier 58, although not required. This is probably best shown in Figures 9-11.
The longitudinal edge of the carrier 58 forms the channel 76. Channel 76 may be made as a contiguous element or may be established by alternating segmented tabs 78, as illustrated in FIGS. 9-11. The carrier 58 slidably meshes with the interface 62 via a channel 76 received on each flange 64. Thus, the frontmost tab 78 slides along the surface 68 of the flange 64, while the rearmost tab 78 engages behind the flange 64 in close proximity to the gutter 66. The carrier 58 is therefore free to slide along the sliding interface 62 and is moved to a position in contact with the recess 70. Once the carrier 58 reaches the terminal position in contact with the recess 70, the carrier 58 is firmly fixed in an appropriate position, assuming that it has reached a predetermined fixed operating position. To prevent the carrier 58 from retracting and returning the sliding interface 62, an additional recess 80 is formed on the flange 64, as best shown in FIG. As an alternative to the recesses 70, 80 due to the impact deformation introduced into the flange 64, the recesses 70, 80 are welded or otherwise the side edge of the carrier 58 is glued to the flange 64. It may be achieved by. In another predictable variant, a channel configuration in which the side edge of the carrier 58 is formed with only a single longitudinally extending rib and the flange 64 receives the rib on either side of the carrier 58. May be reformed into. Further, the sliding interface 62 need not be formed by two opposing longitudinally extending configurations. It is also possible to use a single longitudinally extending feature, such as a rib or channel, in place of the paired feature described above.
Thus, the fuel level transmitter 32 can be moved to one of a number of predetermined positions and then mechanically anchored in place via the sliding interface 62. By adjusting the location of the initial recess 70, the operating position of the fuel level transmitter 32 can be manipulated to produce optimal results. Problems inherent in prior art techniques such as welding and process susceptibility include mounting the fuel level transmitter 32 via an extending sliding interface 62 formed along the exterior of the storage tank 34. Overcome by. Therefore, the present invention provides a more robust and more adaptable fuel supply module structure.
According to another aspect of the invention, a method of assembling the fuel supply module 18 is provided. The method defines a theoretical longitudinal axis A and comprises providing a storage tank 34 with a peripheral side wall 36 for isolating a limited amount of fuel in the tank 14. The method also includes the step of inserting the fuel pump 46 into the storage tank 34. The method also includes the step of attaching the fuel level transmitter 32 to the storage tank 34, which is provided to measure the amount of fuel in the tank 14. The method is highlighted by the mounting steps described above, which include slidably receiving and securely fixing the fuel level transmitter 32 along a capture-type sliding interface 62 located along the side wall 36 of the storage tank 34. .. This method allows the fuel level transmitter 32 to be positioned indefinitely longitudinally along the sliding interface 62 during the assembly process and can be permanently fixed in the desired operating position for subsequent operational use. ..
The invention described above is described in accordance with relevant legal standards, and thus this description is of an exemplary and non-limiting nature. Modifications and modifications of the disclosed examples will be apparent to those skilled in the art and may fall within the scope of the present invention. Therefore, the scope of legal protection granted to the present invention can only be determined by considering the following claims.
