A motorcycle includes an internal combustion engine, a frame, a fuel tank for carrying a fuel to be consumed by the internal combustion engine, and a container connected to the internal combustion engine and the fuel tank. The container is configured to store fuel evaporating from the fuel tank, and the container in a position of use is at least partially covered by the fuel tank. The fuel tank is supported pivotably relative to the frame between a maintenance position and the position of use.

A refueling device that when mounted to a marine fuel tank facilitates refueling and minimizes the propensity for both spit-back and well back while simultaneously allowing a free flowing open pathway through which vapors generated by the refueling event may pass unencumbered.

This disclosure describes an assembly for gas (e.g., compressed natural gas) storage. The assembly includes multiple gas storage tanks, with each tank coupled to a separate sub-assembly that includes a pressure gauge, shutoff valve, and pressure relief device (PRD), providing for independent pressure monitoring, shutoff, and pressure relief for each of the tanks.

A fuel tank for a vehicle, having a plurality of chambers, the chambers fluidly connected to allow a flow of fuel between the chambers, where at least one of the chambers has a flexible fluid container contained within an expandable rigid outer shell.

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 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.
