Claim:
A gas supply system, comprising: a receiver assembly; a gas storage vessel coupled to the receiver assembly; a main poppet positioned at an end of the gas storage vessel and sealing the gas storage vessel when the main poppet is closed; a pilot poppet positioned in the main poppet and sealing the gas storage vessel when the pilot poppet is closed; and a chamber positioned behind the main poppet, wherein a first end of the main poppet located at the chamber has a larger diameter than a second end of the main poppet located at the end of the gas storage vessel, wherein when the pilot poppet opens, gas from the gas storage vessel is released into the chamber to exert pressure on the main poppet to open the main poppet, wherein the main poppet moves into the gas storage vessel into a pressure stream of escaping gas from the gas storage vessel to open the main poppet, wherein a time for the main poppet to move into the gas storage vessel to reach a stop is less than or equal to about 20 ms.
