Device for filling air guns

0001The invention relates to a device for filling a Chamber in a gas-competition barrel with gas, in particular preferably with liquid CO₂ or compressed air.

0002Known gas weapons like those used in sports competitions are, for example, CO₂- Or Preßluftwaffen have, apart compression models and spring-driven models, a storage container for a certain number of shots. Refilling of Vorratsbehalters from larger gas cylinders However, compressed air cylinders or management increasingly somewhat difficult and is usually the most uncomfortable when one decides to go to the shooting, and notice must in that the storage vessel is not sufficiently filled is. Characterized in that the reservoir attached to the gun is to continue increasing the weapon weight. Also is the design option pretty limited because eg for Preßluftwaffen a pressure reducer between reservoir and an intermediate chamber in excess levy will be drained via a valve on removal, switched have to be. Also, the storage, filling the on the gun located reservoir and the subsequent control the required small amount of gas currently very expensive. As an example, CO₂ called: When filling CO₂ Care must be taken that during the filling process of Reservoir is cold and only liquid CO₂ from a separate taken stock bottle into the reservoir becomes. After the brake fluid reservoir is weighed and possibly excess CO₂ be drained to prevent overfilling takes place.

0003The invention is based on the object at a filling device of the type mentioned in the to simplify filling process and facilitate.

0004This object is at a filling device of the mentioned type according to the invention by a separate is charging station, stored in the gas, one with the Chamber in communication adapter on the gun, with the the gun for filling the chamber connected to the charging station , and a manually operable valve at the loading station, through the actuation of the chamber via the adapter can be filled with gas from the charging station.

0005This filling device, the contactors of excess to shot his gun easily with the preferably stationary Connect the charging station and then each in the chamber (Intermediate chamber) of the weapon enough energy for either only the next shot or fueled for several shots. He thus has the possibility of a longer exercise program complete, and this always with almost the same pressure, in particular at a filling with compressed air, because the pressure decrease substantially in a larger reservoir of the charging station is slower than in a normal compressed air reservoir, the conventionally mounted on the weapon is. The drive medium, whether CO₂ or compressed air, by means the charging station shot for shot, during the filling process taken with the weapon. The charging station can optionally with compressed air, CO₂ or other suitable Gas operated. By disengaging the reservoir of the weapon can this now lighter and more be more tailored to the shooter. this leads to greater design freedom in the construction of the weapon at the same time Reduction of arms weight. Thus, on the Reservoir on the gun to dispense, and must only The charging station can be used if necessary to the drive medium from shot to shot in dose form the gun bring.

0006The shooter can eg a filled 3-kg gas supply bottle or 4-liter air tank as a reservoir with the take Schützenhaus, this his weapons under the tray to Shooting place and so, for example by means of a hose connection, educate to a charging station at its shooting range, his weapon respectively by coupling to the charging station, ie to fill to its reservoir. Of the Pressure vessel of the weapon may also in such a filling device be used.

0007In order for the weapon to be filled with a reproducible print can, the adapter is preferably during the filling process centered in the charging station or the filling opening the charging station arranged centered.

0008Since the gas (driving medium) under pressure from the charging station flows into the chamber of the weapon, it is advantageous if the adapter during the filling process by means of a Quick closure is secured to the charging station. This Quick release, such as a bayonet or linear closure or other coupling, eg located at the loading station, Accordingly, while the adapter on the gun is executed.

0009The quick-release fastener and the valve may be separately be operated electrically or mechanically. However, preferred that the valve of the charging station with the rapid closure and / or mechanically coupled to the centering is, so that only a handle for operation of both functions is required.

0010In preferred embodiments of the invention, the valve is by movement of a filling nozzle, to which the Adapter bears, operable. For this, a the inlet pipe force-applying in its valve actuating position Handle, in particular a pivotable lever, be provided. The handle can also for locking the serve quick closure of the through movement open handle in the opposite direction again becomes.

0011To attach the adapter to the charging station at a defined point can, is preferably at the loading station a Recording for the adapter provided.

0012If the chamber to be filled on the adapter releasably retained is, there is the advantage that, depending on requirements chambers with gas supply for only one or more shots to the adapter can be attached.

0013Preferably, the adapter and the chamber are already on the Weapon formed integrally.

0014To also conventional gas pressure guns with as little of later expenditure of the filling apparatus of the invention To connect the adapter, for example, instead an otherwise provided gas reservoir in a corresponding aperture in the gun to be installed. Thereby also reduces the weapons weight to the difference in weight of reservoir and adapter.

0015The invention also relates to a central filling system with a central gas-supply store and at least two, each connected to the central gas-supply store Filling devices, as described above are. By branches of a larger supply bottle may be connected several, for example three or four, charging stations are such that several shooters their weapons directly can refuel from this reservoir bottle. For larger Clubs and events it is possible to have a Central supply all shooters with suitable propellants (CO₂ and / or compressed air) through the respective charging stations to supply.

0016Further advantages of the invention will be apparent from the description and the drawing. Also, the above mentioned features and those further described below in the present invention either individually or collectively in arbitrary find combinations. The illustrated and Described embodiments are as exhaustive understand enumeration but rather have exemplary Character for describing the invention.
