ABSTRACT:
An apparatus for opening a delivery valve in a gas reservoir chamber of a compressed gas operated gun comprises a compressed gas chamber in a cylinder and a gas reservoir chamber adjacent thereto. The gas reservoir chamber is normally closed at the side of the compressed gas chamber by a suction check valve and at the side opposite to the compressed gas chamber by a rod-like delivery valve which also closes a leading hole leading to a barrel bore. The delivery valve is slidably arranged within a through-hole which opens into the gas reservoir chamber at the side opposite to the suction check valve, and is urged by a spring so as to normally close the leading hole, and the rear end of the delivery valve is engaged by a latch lever of a trigger. Upon pulling the trigger to bring the latch lever of the trigger out of engagement with the delivery valve, the compressed gas within the gas reservoir chamber pushes backwards the delivery valve to open the leading hole, so that the compressed gas is introduced into the barrel bore through the leading hole to fire a projectile therein.
