There is provided a high pressure container including a plurality of container bodies, each of the container bodies housing a fluid in a huh pressure state and being able to release the fluid through a release portion, (ii) opening section that is linked to the container bodies, and that opens at or above a predetermined opening temperature to release the fluid inside the container bodies, and (iii) a cover member that straddles the plurality of container bodies, that covers at least a portion of the plurality of container bodies, that is able to withstand a temperature of no less than the opening temperature, that is linked to the opening section, and that is capable of transmitting heat to the opening section.

A storage tank includes a tank wall, a pressure regulator, a low-pressure coupling, and a fill coupling. The tank wall of the storage tank is configured to contain a stored fluid at an internal pressure within the tank wall, the tank wall including an outer layer, an inner layer, and a regulator mount. The pressure regulator of the storage tank is connected to the regulator mount and is configured to receive a flow rate of the stored fluid and reduce the stored fluid from the internal pressure to an output pressure. The flow rate of the stored fluid is provided, via the low pressure coupling and at the output pressure to an external system. The fill coupling extends through the tank wall and receives the stored fluid from a fluid source to be stored within the storage tank

The invention relates to a shut-off valve (1) for a pressurized-gas vessel, comprising a valve closing body (2) which can perform stroke movements and which is preloaded by the spring force of a closing spring (3) against a valve seat (4), such that, when the valve closing body (2) is in a closed position, a connection of a valve inlet (5) to a valve outlet (6) is shut off, and furthermore comprising an actuator arrangement (7) for opening the valve closing body (2). According to the invention, the actuator arrangement (7) interacts with an actuating element (8) which is arranged spaced apart from and coaxial with respect to the valve closing body (2) and which is movable by means of the actuator arrangement (7) in the direction of the valve closing body (2), such that, when the actuating element (8) abuts against the valve closing body (2), an opening impulse can be generated. The invention furthermore relates to a pressurized-gas vessel having a shut-off valve (1) according to the invention.

A control unit for a pressure container system comprising at least one pressure container with a pressure container valve designed to conduct fuel from the pressure container into a removal line for supplying an energy converter. The control unit is designed to determine that a fueling procedure of the pressure container is occurring or has occurred. In response thereto, the control unit is additionally designed to cause the pressure container valve to open in a pulsed manner temporally prior to a removal request for fuel for operating the energy converter so that the pressure in the removal line approximates the pressure in the pressure container.

A thermally activatable safety valve for a pressure vessel includes i) a pressure relief unit having a valve for pressure relief of the pressure vessel; ii) at least one release line which extends away from the pressure relief unit; and iii) at least one bursting device. The release line, the bursting device and the valve are fluidically connected and form a common fluid system. The valve is designed, for pressure relief, to pass from a first closed position into a second open position if the pressure in the fluid system is less than an actuating limit pressure. The bursting device is designed to bring about pressure relief in the fluid system if the pressure in the fluid system exceeds a release pressure.

Heat is transferred from a flow of liquid hydrogen to a flow of a heat transfer fluid at a first heat exchanger to produce a warmed flow of pressurized hydrogen and a cooled flow of heat transfer fluid. Heat is also transferred at a second heat exchanger, to the cooled flow of heat transfer fluid, from a flow of pressurized hydrogen that is derived from one or more buffer vessels filled by the warmed flow of pressurized hydrogen and/or the warmed flow of pressurized hydrogen from the first exchanger to produce a cooled flow of pressurized hydrogen that is used to fill tanks of fuel cell electric vehicles.

The present disclosure provides an insulation support that is disposed in a vacuum space between an inner container and an outer container of a liquid hydrogen storage container composed of the inner container and the outer container, and supports the inner container, in which the insulation support has a first end being in contact with the inner container and a second end being in contact with the outer container, and is bent several times into several layers; and an automotive liquid hydrogen storage container including the insulation support.

A pressure relief valve configured to vent a pressurized tank in the event of a fire is provided. The pressure relief valve includes a body, a vent passage, a plug and a latch. The vent passage is disposed through the body. The vent passage can be placed in fluid communication with an internal volume of a tank and with the atmosphere. The plug is moveably mounted in the vent passage. The latch has a blocking member disposed in contact with a control end of the plug in a first configuration and out of contact with the control end in a second configuration. The second configuration allows movement of the plug in the vent passage. One or both of a shape memory alloy wire and a trigger piston is configured to actuate the latch from the first to the second configuration. The shape memory alloy wire is configured to shorten when exposed to a temperature above a threshold temperature. The trigger piston moves, e.g., by a pressurized gas, in a trigger actuation passage to actuate the latch from the first configuration to the second configuration.

Provided is a pressure vessel capable of adapting a release direction of gas in the pressure vessel (i.e., release-permitted direction) and a direction in which the gas in the pressure vessel should not be released (i.e., release-restricted direction) to an attitude of a vehicle or a surrounding environment. A release direction control unit is configured to variably change, with respect to the pressure vessel, a release direction of gas as a pressure relief valve opens, and without depending on an attitude of the pressure vessel, release the gas stored in the pressure vessel as the pressure relief valve opens (only) in the release-permitted direction set in advance with respect to a gravity direction, not in the release-restricted direction set in advance with respect to the gravity direction.

A pressure vessel (10) is provided with: a cylinder part (1) that defines a pressure chamber (11); a screwing part (3) that is disposed inside at least one of the two ends of the cylinder part; a lid (2) that has a pressure-receiving surface (2A) facing the pressure chamber and that is disposed at a position closer to the pressure chamber than is the screwing part; and a reinforcing ring (4) that is fitted to the outer circumferential surface of the cylinder part. The reinforcing ring covers, along the axial direction of the cylinder part, a part on an outer circumferential surface (1F) corresponding to a portion or the entirety of the engaging portion (12) between the cylinder part and the screwing part.
