ABSTRACT:
A pneumatic gun having an improved firing valve is disclosed wherein the firing valve is sealingly secured to the housing of the gun by a pair of rolling diaphragm seals. On the underside of the firing valve, there is a deflector having a downwardly curled outer edge operative to direct air flow into the top of the cylinder upon opening of the firing valve. The firing valve is so configured that exposure of multiple differential areas of the valve to a common high pressure results in the valve being biased toward a sealed position relative to the cylinder of the gun while in the unfired position.
