Abstract
An air gun with a quick-release pneumatically operated gas valve that includes a piston positioned in a cylinder with one closed end so that the piston may seat against a gas outlet to close the gas valve. A control reservoir filled with gas to a control pressure is formed in the cylinder between the piston and the closed end of the cylinder so that the control pressure acts against the piston to close the gas valve. Opening a trigger valve allows the gas in the control reservoir to escape through an exhaust port, resulting in the gas valve being rapidly opened.
