Gas-storage system

0001The invention relates to a gas storage system according to the preamble of claim 1.

0002There are already known gas storage systems, which are arranged in a motor vehicle are. Further, it is known to fill the gas storage systems with a gas, that is under a high pressure and / or having a low temperature. Preferably, this may be a gas, that is called a "Compressed natural gas", short CNG, act. The known gas storage systems are usually installed transversely in the trunk of a motor vehicle.

0003The object of the invention is to provide a gas storage system, the crash-proof is trained.

0004This object is solved by the features of claim 1.

0005By integrating all safety-critical components, particularly of the check valve, in a housing within the gas cylinder of the present invention Gas storage system is, the crash protection increases. Another Measure to secure the gas storage system is the fact that the housing is arranged on a lid with a support or Abstütselementen are provided in a crash on the outer wall of the gas storage system press, so that the housing and the components contained within it protected are. An additional measure is that a crash protective plate is arranged with a protruding rim on the lid. By overhanging edge of crash protection plate underneath, on the periphery the lid arranged connections also protected. The mounting of the enclosure with the cover is advantageously effected in that in the portion of the open end of the gas cylinder has an internal thread is formed, so that the housing can be screwed into the cylinder.

0006An embodiment of the invention is by way of example below with reference to a Drawings. The single figure shows a cross-sectional view of an upper End 2 of a gas cylinder 1 of a gas storage system. The upper end has 2 one provided with an internal thread 3 opening 4 at a portion 5 of the gas bottle 1 on. The section 5 has a smaller outer diameter d than a including befindlicher portion 6 with an outer diameter D. The outer diameter d lies in the order of approximately d ≥ 50 mm and the outer diameter D is D approximately ≥ 160 mm.

0007In the inner thread 3 of the section 5, a housing 7 is screwed in which integrated all safety-related components of the gas bottle. 1 These components belongs among others a shutoff valve, which preferably operates electromagnetically and is provided with a mechanical release. Further, go through the Sealed housing 7 lines 8 and 9 therethrough. The gas-tight sealing of the Case 7 is carried out in the shown embodiment by an annular seal 10th

0008On an edge 11 of the opening 4, a lid 12 is arranged sealed. Of the Lid 12 consists of a plate-shaped part 13 on the plate-shaped part 13 is a support 14 formed integrally, which extend parallel to a longitudinal center axis 15 toward a connecting portion 16 of the outer wall of the Gas cylinder 1 extends, the formed between the section 5 and section 6 is. The support 14 may be a continuous ring or individual from each other be spaced ridges. In the embodiment shown, the support 14 is by a distance t ≥ 5 mm from the outer surface 17 of the connecting portion 16 spaced. In another embodiment, the support 14 is at the Außenobefläche 17 of the gas cylinder 1 at. In addition, between the Outer surface 17 and the adjacent thereto or spaced therefrom support 14 may be formed a gas tight seal.

0009At the circumference 18 of the plate-shaped part 13 are holes and / or openings for the lines 8, 9 are formed. is on the top side 19 of the plate-shaped part 13 a crash protective plate 20 fixed for example by screws 21st The Crash protection plate 20 has in the plan view of a hexagonal shape. An edge 22 stands above the cover 12 by an amount a as far above that the terminals 23, 24 of the lines 8 and 9 are protected at the periphery 18 of the cover 12th The supernatant a is in the shown embodiment, at least a ≥ 10 mm.
