The invention relates to a device (10) for supplying a fuel consumer (1) of a vehicle (20) with a gaseous fuel. The device (10) comprises multiple pressure accumulators(2) for storing and providing pressurised fuel, as well as a discharge device (3), which fluidically connects the multiple pressure accumulators (2) with the fuel consumer (1). In order to advantageously allow for a utilisation of a temperature change occurring during a fuel discharge, preferably a discharge cold temperature released during the discharge of fuel, according to the invention, the discharge device (3) is thermally coupled to a coolant circuit (4) of the vehicle (20). The invention also relates to a vehicle (20) comprising a device (10) of this type.

A tank comprises a shell, delimiting a storage enclosure and having at least one opening, and a connection me connected to the at least one opening of the shell. The connection member_-comprises a tubular element, delimiting a duct, and an annular element. The shell comprises a rim delimiting the at least one opening, the rim being radially clamped between the tubular element and the annular element.

The invention relates to a hybrid pressure vessel with a fiber-composite component and a metallic component. Furthermore, the invention relates to a manufacturing method for such a hybrid pressure vessel. The hybrid pressure vessel according to the invention has a liner having an inner face and an outer face, with an outer diameter DL, and a metallic boss with an outer diameter DB, the metallic boss being adapted to accommodate a valve, the hybrid pressure vessel having a storage volume on the inside, the liner being pipe-shaped and the outer diameter DB of the boss being at least as large as the outer diameter DL of the liner.

A high-pressure tank and a method of producing such a high-pressure tank. The high-pressure tank includes a liner composed of plastic, a shell of the liner, and at least one boss having at least at one contact surface with a plastic coating that contacts the liner. The plastic coating forms a seal between the at least one boss and the liner such that there are no other sealing elements therebetween.

Disclosed are thin-walled metal liners, for composite tank, type III, preferably designed to contain gases or hydrogen under high pressure, intended for land, sea, air and space transport, as well as static storage. This liner consists of a main cylinder of revolution, terminated, at least at one of its ends, by an evolutionary shape, substantially hemispherical, gradually connecting to its pole on a cylindrical part of smaller diameter than the main cylinder, the second end of the main cylinder may be either substantially identical to the first, is called “one-eyed” that is to say that it has an evolutionary shape, substantially in the entire hemisphere, that is to say without cylindrical part of smaller diameter than the main cylinder, at its pole.

A high-pressure tank includes a liner that includes a body that is cylindrical in shape and a pair of dome portions each of which is provided at a respective end of the body in an axial direction, and a reinforcing layer provided on an outer circumferential face of the liner. The reinforcing layer includes a pair of resin rings each of which is provided encircling a respective end portion of an outer circumferential face of the body, a hoop layer that covers part of the outer circumferential face of the body, between the resin rings, and a helical layer that covers the resin rings, the hoop layer, and the dome portions. The resin rings are configured to cover part of the body from boundary portions between the body and the dome portions, and increase in thickness from the boundary portions toward a middle of the body.

An apparatus includes a high-pressure tank, a controller, a valve, controlled by the controller, and a heater.

A pressure vessel includes a liner including a cylinder part and side parts provided at both ends of the cylinder part, each side part having a dome shape, and a carbon fiber layer including a first hoop layer surrounding a part of an outer circumferential surface of the cylinder part and second hoop layers surrounding other parts of the outer circumferential surface of the cylinder part, each of the second hoop layers having a thickness different from a thickness of the first hoop layer.

A pressure vessel system for a vehicle includes a pressure vessel and a fuel line. The system also includes a blocking unit which, in an inoperative state, prevents fuel from passing out of the pressure vessel into the fuel line. A control unit for the blocking unit is designed, under the action of electrical energy, to transfer the blocking unit from the inoperative state into an active state in which fuel can pass out of the pressure vessel into the fuel line. Furthermore, the system includes an electrically conducting connection to an electrical system of the vehicle via which electrical energy can be provided for controlling the blocking unit. In addition, the system includes an access interface unit via which electrical energy for controlling the blocking unit can be provided from an external energy supply if no electrical energy is available from the electrical system of the vehicle.

A tank mounting structure includes a frame, a band, and a tank protector. The frame is configured to fix the tank. The band is configured to fix the tank in a state where the band sandwiches the tank with the frame and the band deforms in accordance with expansion or contraction of the tank. The tank protector is configured to be fixed to an inner side of the band or an outer side of the band.
