A hydrogen storage device provided in a vehicle that uses hydrogen as a fuel includes a plurality of receptacles, a plurality of hydrogen tanks, and a flow channel through which hydrogen flows from the receptacles to the hydrogen tanks. The flow channel has a confluence point configured such that the hydrogen merges into one on a downstream side of the plurality of receptacles. The flow channel branches from the confluence point into the plurality of hydrogen tanks.

A mount for a double-walled vessel includes a first support to support the mount against an outer wall of the double-walled vessel, a second support to support the mount against an inner wall of the double-walled vessel, and a flexible member connecting the first support and the second support. The first support and can be arranged at a first end of the flexible member and the second support can be arranged at a second end of the flexible member opposite to the first end. Further described are a vessel including at least one such mount as well as a vehicle including such vessel.

The present invention discloses a boss configuration for a Type IV composite pressure vessel (“CPV”). In particular, the invention provides liner-to-boss interface that allows the polymeric liner to wrap around the internal collar of the boss that extends below the flange. Since the wrap-around section of the liner conforming to the internal collar portion of the boss is subjected to pressure from all sides, the liner stays adhered to the boss when the inside surface of the liner in a CPV is subjected to internal pressure from the contained fluid.

A pressure vessel includes: a barrel part disposed in a predefined square area and having a diameter corresponding to a length of one side of the square area; a first nozzle member disposed at one end of the barrel part; a second nozzle member disposed at an opposite end of the barrel part; and clamp rings disposed in the square area, positioned outside the barrel part, and configured to lock the first and second nozzle members to the barrel part, thereby improving spatial utilization and a degree of design freedom.

The invention relates to a valve device (100) for a gaseous medium, in particular hydrogen, comprising a valve housing (6) which comprises a closing element (14) that is arranged therein and can be moved in the longitudinal axis (18). The closing element (14) interacts with a seal seat (16) in order to release and close a through-opening (22). The valve housing (6) is equipped with at least one spring element (8) which is supported against the closing element (14) and the valve housing (6). Furthermore, the at least one spring element (8) is made of a bimetal.

The invention relates to a pressurized fluid storage and dispensing assembly (1) for a vehicle, comprising: a plurality of pressurized fluid reservoirs (3), each reservoir (3) comprising a first end piece (13) provided with at least one fluid passage duct configured for dispensing fluid from the reservoir (3) and for filling the reservoir (3), a use collector duct (5) which comprises an opening (19) for supplying and/or dispensing fluid and a plurality of orifices, each orifice being configured to be fluidically connected to a reservoir (3) via its fluid passage duct, and an electrically operated valve (7) which is arranged at one end of the use collector duct (5) and selectively closes or opens the fluid passage through the opening (19).

The invention also relates to a vehicle comprising such a storage and dispensing assembly (1).

The invention relates to an indoor safety device for a liquefied fuel gas system, the system comprising a storage device storing liquefied fuel gas; a vent member arranged in fluid communication with the gas inside the storage device; and a safety valve arranged to evacuate gas when the pressure inside the storage device exceeds a predetermined first value, the safety device comprising: a vent coupling; a pressure relief valve arranged downstream of the vent coupling; and a conduit for conveying gas, adapted to be connected to the pressure relief valve, the safety device being removably connected to the system by connecting the vent coupling to the vent member, wherein the pressure relief valve is configured to release gas when the pressure inside the storage device exceeds a predetermined second value, lower than the first value.

Gaseous fueling systems and methods are provided for dispensing fuel to a vehicle or container. The distribution systems speed up the filling process and may eliminate the use of expensive cooling systems required in the art. The methods utilize sequences of filling and emptying the vehicle gas storage tank to control the temperature of the gas inside the tank. These filling and emptying sequences may overlap. The methods repeatedly dispense fuel to the vehicle fuel tank at a first flow rate and for a first period of time and remove fuel from the fuel tank at a second flow rate for a second period of time, which periods may overlap, to maintain fuel temperature within a desired temperature range and until the vehicle fuel tank is filled to a desired level. In addition, the fill-up mass flowrate can be maximized to system capabilities so a fill-up can be completed in about one minute.
