An integrated pressure regulator is provided with three stages configured to reduce an extreme tank pressure down to a typical working pressure. The regulator is configured to supply a steady working pressure until the tank pressure is reduced to little more than the working pressure itself. Stages of the pressure regulator are integrated into a body and arranged to minimize regulator mass and volume. A thermally-triggered pressure relief device may be included with a triggering time adapted to enhance the safety of smaller cylinders that may be used, e.g., in aerial applications.

An actuator is disclosed herein. The actuator includes a drive body including a bottom surface, the bottom surface having a first side and an opposing second side, a magneto strictive material disposed within the drive body and contacting the first side of the bottom surface of the drive body, a solenoid disposed within the drive body and surrounding the magneto strictive material, a drive rod extending through the magneto strictive material and through the bottom surface of the drive body, and a spring disposed adjacent the second side of the bottom surface of the drive body, wherein the drive rod extends through the spring.

A valve may have a valve body having a lateral wall, a passage opening and a vertical filling opening and a vertical inflow opening. The passage opening may extend from the vertical filling opening to the vertical inflow opening. In a filling position of the valve, the passage opening may be closed from the lateral wall in a media-tight manner and the filling opening may be fluidically connected via the vertical passage opening to the vertical inflow opening. A pressure vessel may utilize the valve.

An initiator for opening a pressurized gas cylinder is disclosed herein. The initiator includes a housing having a first end and a second end, a lance disposed within the housing, the lance configured to slide from the first end of the housing to the second end of the housing and out through the second end of the housing, a spring disposed within the housing between the first end of the housing and the lance, and a wire coupled to the first end of the housing and to the lance, the wire configured to hold the spring in a compressed state, the wire further configured to break in response to an electric current.

A compressed gas storage unit (1) for mobile applications, in particular for storing hydrogen on board a vehicle, including at least one metal storage housing (2) which delimits a storage volume (3) that can be filled with compressed gas, as well as at least one temperature-and/or pressure-sensitive overload valve (4) arranged on the storage housing (2). The storage housing (2) or the compressed gas storage unit (1) is surrounded by a heat protection shield (5) at least in regions, preferably releasing the at least one overload valve (4).

Systems and methods are provided herein for gas storage and the safe release of gas using cascading burst discs. A vessel for storing gas is in pneumatic communication with a first flow path. A first burst disc is disposed in the first flow path such that gas flow is prevented when the disc is intact. A second flow path is in pneumatic communication with the first flow path and configured to receive gas flow when the first burst disc is ruptured. A second burst disc is disposed in the second flow path and configured to prevent a gas flow while the second burst disc is intact. At an operating pressure, the first burst disc may be punctured by an operator allowing normal use of the system. In the event of a gas overpressure, the first and second burst discs will rupture permitting safe release of the gas.

A pressurization device for pressurizing an enclosure may include a container containing a pressurized fluid, a pin that is inserted into the container, an actuator, and a heating device operably coupled to the actuator. The actuator may initially hold the pin in a closed position and allow the pin to move to an open position, disengaging from the container when the actuator increases in temperature. The pressurized fluid may force the pin toward the open position to release the pressurized fluid from the container. The actuator may include a frangible hollow bulb configured to fracture at a pre-defined temperature. The pressurized fluid may be vented into the enclosure through at least one fluid passage in fluid communication between the enclosure and the container.

A cryogenic cylinder including authenticating features and an apparatus recognizing the features and facilitation the cylinder use. The authenticating features prevent use of an unauthorized cryogenic cylinders. The cylinder also includes a number of mechanical features preventing repeat filling of the cylinder by cryogenic fluid or reuse of the cylinder once empty.

The invention relates to a valve for pressurized fluid, the valve having a body incorporating a fluid circuit having an upstream end and a downstream end, the circuit having a seal valve, the seal valve enabling the circuit to be opened or closed, the valve having a member for controlling the seal valve, the seal valve being slidably mounted in the body so as to slide between a position in which the circuit is closed when the control member is in a rest position and a position in which the circuit is open when the control member is in an active position, the valve having a deformable member positioned between the seal valve and the control member. The invention also relates to a container or a set of containers for pressurized fluid comprising such a valve.

An aeronautical cryogenic tank device for storing gas, having a spherical or annular shape about an axis, comprising an inner container (26) defining a liquefied gas storage chamber (28), an outer envelope (27) containing the inner container (26), an insulation chamber (29) defined between the inner container (26) and the outer envelope (27), the reduced-pressure insulation chamber (29) having scaling equal to or better than 10-9 millibar*litre/second, a removable collector (38) passing through the outer envelope (27) and the inner container (26) in a sealed manner, the collector (38) extending over a diameter or a diagonal of the inner container (26) and having a free end close to a bottom of the inner container (26), and a conduit supplied by the collector (38).
