Claim Text:
1. An automatic gas purge valve comprising a housing configured with an automatic gas purge valve system comprising a normally closed gas discharge faucet having a control chamber, the gas discharge faucet being configured with a fluid inlet port being in flow communication with the housing and a fluid discharge port configured for discharging gas at substantially high flow rates; and an automatic valve unit having an inlet port in flow communication with the housing and an outlet port being in flow communication with the control chamber, and configured for selectively generating a flow pulse at the control chamber to displace the gas discharge faucet into its open position; wherein the automatic valve unit is manipulable between a closed position and an open position solely responsive to liquid level within the housing; wherein the automatic valve unit is configured with a flexible closure membrane secured at one end to the housing and at an opposite end to a membrane displacing member; and wherein displacement of the membrane displacing member in a downwards sense progressively detaches successive transverse portions of the flexible closure membrane so as to open the outlet port towards the open position of the automatic valve.
