A system provides regulated delivery of a high-pressure gas. A first flow path, coupled to a high-pressure gas source, is in fluid communication with a chamber. A flow restrictor, disposed in the first flow path, slows the gas traveling along the first flow path to the chamber. A second flow path, coupled to the high-pressure gas source, is in fluid communication with the chamber. A third flow path connects the chamber to a pressure regulator. A valve, disposed in the second flow path, seals the second flow path when gas pressure at the source exceeds gas pressure in the chamber. The valve opens the second flow path when the gas pressure at the source is balanced with the gas pressure in the chamber allowing the high-pressure gas to flow to the regulator via the third flow path.

Gas temperature reducing system for regulating delivery of a high-pressure gas

A pneumatic valve controller is provided for use with a refillable gas tank that has an inlet and an outlet with a spring-loaded valve disposed in the outlet. The spring-loaded valve is biased to define a flow path between an interior of the gas tank and the outlet. The controller's housing includes a cylinder with a gas filling port in fluid communication with a first axial end of the cylinder. The cylinder's second axial end is open and aligned with the spring-loaded valve. A piston is disposed in the cylinder. A check valve has an input and an output with the input in fluid communication with the gas filling port and the output in fluid communication with the inlet of the gas tank.
