High pressure container
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.
Pressure vessel mounting structure
A pressure vessel mounting structure includes: a manifold including a discharge gas passage branching from a general passage via which a container body communicates with a valve; a fusible plug valve configured to close the discharge gas passage and to, when the fusible plug valve is melted, open the discharge gas passage such that the high-pressure gas is discharged; a case including a bottom face portion covering the container body and the manifold from below in the vehicle up-down direction, the case including a bead placed near the fusible plug valve, the bead being formed by protruding a part of the bottom face portion upward in the vehicle up-down direction; and a communicating opening via which a space under a floor of a vehicle communicates with the fusible plug valve, the communicating opening being formed in a part of the bead, the part facing the fusible plug valve.
Multi-Function Three-Stage Pressure Regulator
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.
Tank and manufacturing method for tank
A manufacturing method for manufacturing a tank includes: a step of forming a structural body constituted by a liner and a fiber reinforced resin layer placed on the outer periphery of the liner, the structural body including a cylindrical portion and dome portions provided in opposite ends of the cylindrical portion in the axial direction of the cylindrical portion; a step of winding a heat insulating sheet around the fiber reinforced resin layer after the step of forming the structural body, the heat insulating sheet having notches in dome forming portions provided to correspond to the dome portions; and a step of covering the dome portions with the dome forming portions.

COMPRESSED GAS STORAGE UNIT, AND VEHICLE COMPRISING A COMPRESSED GAS STORAGE UNIT
The invention relates to a compressed gas storage unit (1) for mobile applications, in particular for storing hydrogen on board a vehicle, comprising 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). According to the invention, the storage housing (2) or the compresses 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). The invention also relates to a vehicle comprising a compressed gas storage unit (1) according to the invention for storing hydrogen.
System for multiple pressure relief device activation
A system includes a first valve fluidly connected to a first vessel and a second valve fluidly connected to a second vessel. The first valve includes a body and a piston. The body includes first and second ports and a bore having a longitudinal axis. The first port is in communication with the bore and an interior of the first vessel. The second port is in communication with the bore, the second valve, and an atmosphere exterior to the first vessel. The piston is movable along the longitudinal axis of the bore. A first position of the piston blocks the first port; a second position of the piston allows fluid communication between the first and second ports. The first valve is configured so that fluid pressure from the second valve, communicating through the second port, urges the piston to the second position.
