A pressure vessel is disclosed, the pressure vessel having an outer shell, an inner shell, and a temperature regulating device, the temperature regulating device adapted to regulate the temperature of a fluid stored in the inner shell during operation of the pressure vessel and to minimize curing time during manufacture of the pressure vessel.

Temperature regulating device for a pressure vessel

One exemplary embodiment includes a gas storage tank comprising a structural outer layer, an internal liner layer, an annular boss, and a liquid sealant disposed between the overlapped section of the liner layer and the boss to provide a gas-tight seal.

Gas storage tank comprising a liquid sealant

A pressure vessel for storing a fluid is disclosed. The pressure vessel includes a vessel liner forming a hollow tube and including a plurality of layers with an aperture formed therein, wherein at least one of the layers is a barrier layer and an end cap coupled to the vessel liner, wherein the end cap has a plurality of layers, and wherein at least one of the layers of the end cap is a barrier layer.

Extruded tube welded vessel liner with injection molded end caps

A boss system for a pressure vessel includes a boss and a capture sleeve. The capture sleeve is substantially embedded within a liner of the pressure vessel adjacent a vessel opening. The capture sleeve is provided with a plurality of attachment members configured to cooperate with the boss to secure the boss to the liner of the pressure vessel. The boss system minimizes the effects of pressure and temperature variations during use of the pressure vessel, militates against an axial and rotational movement of the boss, and facilitates installation and replacement of a seal disposed adjacent the boss.

Embedded reinforcement sleeve for a pressure vessel

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.

Pressure vessel including ceramifying polymer for improved heat resistance

A vessel and method for forming the vessel is disclosed, the vessel having an injection blow molded hollow liner, wherein the hollow liner includes reinforced interfacial features formed substantially around a portion of at least one vessel penetration element.

Method for producing a liner of a vessel

A pressure vessel for storage of a pressurized fluid is provided. The pressure vessel includes a composite layer having an outer surface and an inner surface. The inner surface defines an internal cavity. The pressure vessel further includes at least one pressure relief device in fluid communication with the internal cavity. At least one thermally conductive element is continuously wound on the outer surface of the composite layer and adapted to carry load and transport heat from a heat source adjacent the composite layer to the at least one pressure relief device. A method for producing the pressure vessel is also provided.

Activation of a pressure relief device

A seal assembly is disclosed including a support member, a first seal, a second seal spaced apart from the first seal, and a third seal, wherein the first seal militates against a leakage of fluid when an interior of an article to be sealed is subjected to at least one of temperatures below a predetermined temperature and pressures below a predetermined pressure, and the second seal and the third seal militate against the leakage of fluid when the interior of the article to be sealed is subjected to at least one of temperatures above the predetermined temperature and pressures above the predetermined pressure.

Article seal assembly

A seal for a vessel is disclosed which militates against a leakage of fluid during expansion and contraction of the vessel due to changes pressure and temperature. Inner sealing surfaces of the seal form substantially fluid-tight seals in response to at least one of temperatures below a predetermined temperature and pressures below a predetermined pressure and outer sealing surfaces of the seal form substantially fluid-tight seals in response to at least one of temperatures above the predetermined temperature and pressures above the predetermined pressure.

Temperature and pressure responsive seal

A process for manufacturing a compressed gas tank that includes a combination of an injection molding process and a rotomolding process. In a first step, a boss to be positioned in the opening of an outer structural layer of the tank is provided and a thin portion of the liner is injection molded to the boss so that a channel within the boss is filled with the liner material to increase the seal integrity between the boss and the liner. Once the liner material is hardened, the surface of the injection molding liner portion is cleaned. Next, a rotomolding process is performed to mold the remaining portion of the liner to the boss. During the rotomolding process, the injection molded portion of the liner melts to be part of the liner made during the rotomolding process.

Manufacturing process for hydrogen pressure tank

A heat pipe is disclosed, the heat pipe capable of transferring heat to actuate a pressure relief device by heat transfer through either capillary action involving a wicking material and a working fluid, or by a consumable fuse in the case of leakage of the working fluid from the heat pipe.

Modified heat pipe for activation of a pressure relief device

A pressure maintaining system for a hydrogen storage system includes a hydrogen supply feed that enables a hydrogen flow from the hydrogen storage system. A liquid phase hydrogen feed enables a liquid phase hydrogen flow to the hydrogen supply feed. A gas phase hydrogen feed enables a gas phase hydrogen flow to the hydrogen supply feed. A check valve enables fluid communication from the hydrogen supply feed to the liquid phase hydrogen feed when a pressure within the hydrogen supply feed is greater than a threshold pressure.
