Pneumatic weapon with pressure reduction valves

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