Abstract:
A system for supplying compressed gas from a relatively high pressure compressed gas source to a gas chamber such that the gas chamber is rapidly filled with compressed gas to a preselected pressure, the system comprising:a fluid pathway interconnecting the gas source with the gas chamber;a regulator valve arranged in the fluid pathway and operable to rapidly move between an open position permitting relatively high pressure gas from the source to flow into the gas chamber at a supply pressure and a closed position isolating the compressed gas source from the gas chamber;a valve regulator assembly adapted to move the valve to the closed position when a predetermined pressure of compressed gas which is less than the supply pressure is sensed and urging the regulator valve to the open position when a pressure less than the preselected pressure is sensed,a flow control valve arranged in the fluid pathway interposed between the gas chamber and the regulator valve and having an open position for permitting gas to flow through to the gas chamber and a closed position wherein the gas chamber is sealed from the compressed gas source, anda sensing line in fluid communication with the valve regulator assembly disposed to sense the pressure in the gas chamber, the sensing line applying the sensed pressure of the gas in the gas chamber to the valve regulator assembly.
