Paint ball gun |
摘要 |
A paint ball gun is connected through a first gas pressure regulator to a supply of pressurised gas for maintaining a high gas pressure in a first chamber in the gun and a second gas pressure regulator is connected between the first chamber and a second chamber in the gun to maintain a working gas pressure in the second chamber greater than atmospheric pressure but less than the gas pressure in the first chamber. A pneumatic control valve is arranged to receive gas under pressure from the second chamber and direct it selectively to a pneumatic ram mounted for sliding movement in a cylinder in the gun between a retracted position and a forward position in which it opens a valve to admit high pressure gas from the first chamber to the barrel to fire a paint ball. An electrical switch for the control valve is connected to an electronic control circuit which incorporates a micro-switch operated by the trigger of the gun.
