A liquid tank for a liquid system of a vehicle, comprising a tank housing for storage of a liquid of the liquid system, wherein the tank housing is designed as multiple shells and has at least two tank housing shells that are joined to one another, and at least one flow passage of the liquid system, which flow passage is integrated in the tank housing. At least one of the at least one flow passages integrated in the tank housing is formed by two joined tank housing shells of the at least two tank housing shells.

A high-pressure container unit includes: a box-shaped case mounted on a vehicle and configured to include a bottom portion, a ceiling portion, and a peripheral wall portion; a plurality of container main bodies arranged in an interior of the case and each having a cylindrical body portion; and a reinforcing member extending along an axial direction of the container main body, the reinforcing member being provided in at least one of a space surrounded by the container main bodies adjacent to each other and the bottom portion and, a space surrounded by the container main bodies adjacent to each other and the ceiling portion.

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 fuel tank includes an outer component including an outer panel forming a tank outer shell and an inlet plate formed separately from the outer panel, an inner component including an inner panel forming a tank inner shell and an inner connection plate formed separately from the inner panel, and a pipe passing through inside of the outer panel and the inner panel and connecting the inlet plate and the inner connection plate. The inlet plate is joined to the outer panel, the inner connection plate is joined to the inner panel, and the inner panel is joined to the outer panel.

The invention relates to a method for producing a liquid container for a motor vehicle, having the method steps: providing a wall, which is provided in order to delimit an interior chamber of the liquid container for receiving a liquid; providing a structure, which is provided in order to be arranged in order to reduce sloshing noises in the interior chamber of the liquid container, wherein the structure comprises a random arrangement of threads cross-linked with each other and wherein a plurality of the threads of the structure are integrally joined, at least in sections, to at least one or more additional threads of the structure, such that a substantially monolithic structure is formed; connecting the structure to the wall.

The present invention relates to an all in one fuel tank assembly, and a process of manufacturing the same, for use in commercial vehicles, and more particularly, to an all in one fuel tank assembly that allows multiple components to be manufactured as a single integral structure, such as a single extruded device including a draw tube, a return tube, a fuel sender device, and a vent, for example.

The present invention relates to an isolation flange for a fuel tank assembly, and a process of manufacturing the same, for use in commercial vehicles, and more particularly, to an isolation flange for a fuel tank assembly that provides a crumple zone positioned between a component receiving base and a wall of a fuel tank, such that the crumple zone insulates the component receiving base from deformation during drop tests and harsh environmental driving conditions to which the fuel tank is subjected.

A method for producing a plastic tank includes preparing a tank wall as a hot extrudate. A reinforcing sheet is then attached to at least one region of the outer layer of the hot extrudate. After introducing the attached reinforcing sheet and the hot extrudate into a shaping tool, the shaping tool performs shaping of the hot extrudate and the attached reinforcing sheet to form the tank wall, while simultaneously enhancing the attachment of the reinforcing sheet to the tank wall.

An internal support part structure for a plastic tank includes a support rod and end surface components disposed at two ends of the support rod. The support rod is made of a first material. An outer surface of the end surface component is covered by a second material. An outer edge of the end surface component has a regular or irregular shape. The structure resolves a problem that a second material wrapping a first material and connected to an inner wall of a plastic tank may be easily pulled off the inner wall. When a fuel tank is impacted, the support rod of the structure breaks first, to protect the surface of the fuel tank from damage.

A vehicle tank, in particular for holding a fuel, in particular gasoline and/or diesel fuel, having: a first and a second partial shell, wherein the first and second partial shell are connected to one another in a partial shell joining area, and a barrier layer substantially, preferably completely, covering an outer surface of the first partial shell and an outer surface of the second partial shell, respectively, wherein the barrier layer spans the partial shell joining area on an outer surface of the vehicle tank.
