Sealing assemblies may include a boss, a valve, a liner that defines a containment volume of a pressure vessel, and a support member adapted to cooperate with the liner and the valve. The support member may be formed from an anodized electrically conductive support material and generally has nonconductive surfaces in contact with the valve and the liner. Annular recesses having conductive surfaces are provided in the support member, and seals formed of conductive materials or having conductive surfaces are seated in the annular recesses. Thereby, when the valve is present in the sealing assembly, electric continuity between the valve and the liner is established through the electrically conductive surfaces of the seals, the electrically conductive surfaces of the annular recesses and the electrically conductive support material in the core of the anodized support member.

Sealing assemblies and pressurized fluid vessels including the sealing assemblies

A thermal pressure relief device (TPRD) including a housing having a movable member and a retainer disposed therein. The movable member is movable between an open position and a closed position. A trigger mechanism is disposed between the movable member and the retainer. The trigger mechanism holds the movable member in the closed position and includes a substantially spherical shaped body and a temperature sensitive material disposed in the body. The temperature sensitive material volumetrically expands with an increase in temperature until a predetermined temperature is attained and a breakage of the body occurs. When the body of the trigger mechanism breaks, the movable member is displaced from the closed position to the open position, allowing a fluid to flow through the TPRD.

Thermal pressure relief device

A vessel for holding a pressurized fluid is disclosed, the vessel having a hollow inner shell formed from a moldable material and forming a cavity therein, an intermediate shell formed over the inner vessel, and an outer shell formed over said intermediate shell, said outer shell having a ceramic layer formed on an outer surface thereof.
