The nozzle guide includes on an one end side thereof an annular covering portion configured to cover annularly the outer circumferential surface of the other end side of the fuel filler pipe body. An annular rubber sealing member configured to seal between an inner circumferential surface of the annular recessed groove and an inner circumferential surface of the annular covering portion fits with the annular recessed groove.

A tank mounting adapter is provided that includes a tank adapter disc and a compression nut. The tank adapter disc includes an opening disposed therethrough, which may be sized to receive at least a portion of the support structure of the fluid pump. The compression nut may include a collar with a threaded opening disposed therethrough such that threads of the threaded opening are configured to correspond to threads on the support structure of the fluid pump. The compression nut may be located adjacent the tank adapter disc. The collar may further include a lower portion that extends into the opening of the tank adapter disc. The compression nut may be movable with respect to the tank adapter disc and against the tank adapter disc.

The present invention relates to a curve-combined square pressure tank with which curves are combined so as to maintain internal high pressure, improve space efficiency, and reduce the weight thereof, and to a pressure tank, in which planes and curves are combined, formed by connecting flat plate members and curved members, having a plurality of aligned tension members for connecting the flat plate members facing each other, and having stress buffer parts formed at connection parts of the flat plate members and the curved members so as to enable internal pressure to be maintained.

A valve device includes: a housing; a float valve; and a float valve support portion. The float valve support portion includes a support wall, a side wall, a first slit formed in the support wall, a second slit formed in the side wall, and an elastic piece defined by the first slit and the second slit. The elastic piece includes a first extending portion extending along the side wall, and a second extending portion extending from the first extending portion and capable of coming into contact with a bottom surface of the float valve.

A portable fuel tank assembly includes a portable fuel tank for holding fuel and a support to be connected to a supporting surface for holding the fuel tank stationary with respect to the supporting surface. The fuel tank has a first quick connector for fluid communication with the fuel in the fuel tank. The support has a second quick connector for mating and providing fluid communication with the first quick connector. The fuel tank and support are configured such that securing the fuel tank in the support simultaneously mates the second quick connector to the first quick connector to provide for fluid communication between the second quick connector and the fuel in the fuel tank. A support for holding a portable fuel tank is also provided.

A motor vehicle tank, having a first tank shell and a second tank shell, the first tank shell and the second tank shell defining between each other at least one section of a tank volume of the motor vehicle tank, the first tank shell and the second tank shell respectively having an edge area having a joining flange, the first tank shell and the second tank shell being integrally joined to each other at their joining flanges across a common joining surface, the first tank shell and the second tank shell respectively being a multicomponent tank shell, which includes a barrier film and at least on its edge area an inner wall section that is injection molded onto the inner side of the barrier film pointing toward the tank volume as well as an outer wall section injection molded onto the outer side of the barrier film pointing away from the tank volume, wherein the barrier film of each tank shell is formed in such a way that with the approach to the common joining surface in the area of the joining flange it runs away from the tank volume and toward the outer tank side, so that an integral joint of the tank shells is formed from a first joining area situated closer to the tank volume, in which the injection molded inner tank wall sections of the two tank shells are joined to each other, and a second joining area situated further removed from the tank volume, in which the barrier films of the two tank shells are joined to each other.

A motorized vehicle tank, having a first tank shell and a second tank shell, where the first tank shell and the second tank shell between them define at least one section of a tank volume of the motorized vehicle tank, where the first tank shell and the second tank shell are connected with each other, where at least one tank shell out of the first and the second tank shell is a multicomponent tank shell which exhibits a barrier foil and at least area-wise an inner wall section injected by injection-molding onto the internal side of the barrier foil facing towards the tank volume and/or an outer wall section injected by injection-molding onto the external side of the barrier foil facing away from the tank volume; the motorized vehicle tank exhibits in at least one tank wall section formed from the multicomponent tank shell an eversion formed integrally at the barrier foil, which projects relative to the tank wall region surrounding it.

A flange cover has multiple receptacles for receiving guide bars for a conveyor module at different angles. Further, a conveyor module arrangement has a flange cover of this kind, an operating medium container has a conveyor module arrangement of this kind, and a modular operating medium container system has a plurality of operating medium containers of this kind.

The invention relates mainly to a fuel tank (10) that can be adapted to several types of motor vehicle engines, comprising: —a casing (11) defining a fuel filling space, —a fuel filler pipe (12), and —a gauge/pump module (13), characterized in that the casing (11) has a shape that is suitable for covering different types of gasoline and diesel engines, and in that the casing (11) comprises passages (15) for routing and holding pipes and/or wiring harnesses, the passages (15) formed in advance in the casing (11) being capable of covering routes for pipes and/or wiring harnesses of different types of gasoline and diesel engines, such that some passages (15) used for the pipes and/or wiring harnesses of a given engine are present for an engine of another type but not used.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
