ABSTRACT:
A pneumatic gun has a hollow cylindrical bolt which moves in a housing, being spring-biased to a cocked position. The bolt has a pressure inlet which is coupled to an outlet so that, when air under pressure is supplied to the inlet, the pressure and the drag of the air passing through the bolt urges it forward, carrying a projectile into the gun barrel. The air pressure is sustained until the projectile is propelled out of the barrel. A regulator valve reduces the pressure of gas from a holding tank in the weapon to the operating pressure of the control system. The required pressure for the firing valve may be derived from the control system, from a separate regulator, or from the holding tank. In one embodiment, a special firing valve controls the transmission of firing pressure to the bolt. A pneumatic firing control circuit is triggered by one, several, or a continuous series of electronic pulses to produce single, burst, or continuous fire. The pneumatic gun can be designed to simulate the operation of an automatic firearm.
