Abstract
The present invention is a lightweight high pressure tubular storage system for storing and transporting a gas which includes a tubular member being formed from a metallic or composite material and having an opening in the first end and preferably an opening in the second end. The storage system also includes an inlet valve for bringing a cryogenic fluid into the tubular member wherein the preferred inlet valve is a high pressure ball valve which is fluidly coupled to the first end and an outlet valve for regulating the flow of a compressed gas from the tubular member. The outlet valve is an ambient pressure balanced piston-type valve which has a needle valve shut-off mechanism for positively shutting off the flow of the compressed gas and which is preferably fluidly coupled to the second end whereby the cryogenic fluid which is introduced through the inlet valve is contained and allowed to warm up within the tubular member and change into the compressed gas. The outlet valve also has a flow limiting inlet orifice which is fluidly coupled to the second end of the tubular member. The ambient pressure is sensed by means of a fluid filled passage in which the fluid is retained by an elastomeric diaphragm. The present invention is also a method of filling a storage system with a cryogenic liquid at a temperature below the boiling point of the cryogenic fluid and enclosing the cryogenic liquid so that it can warm up to a temperature above its critical temperature in order to change into a compressed gas.
