AN AIR GUN WITH A DUAL PILOT VALVE-CONTROLLED MAIN VALVE MECHANISM.

Abstract

The invention is an air gun comprising a body (10); a filling tube (20) in which compressed air is stored; a barrel (30) into which the compressed air from the filling tube (20) is transmitted; a main valve (40) which controls the passage of compressed air from the filling tube (20) to the barrel (30) and closes the passage of air to the barrel (30) in a closed position (Kk); a hammer (60) driven by a hammer spring (62) and an automatic trigger group (64) which releases the hammer (60).It includes a relief valve (50) which, when actuated by a hammer (60), releases the compressed air trapped in a back pressure zone (Abb) of the main valve (40), causing the main valve (40) to open with an opening direction movement (Ayh) away from the barrel (30) by the air pressure force from the filling tube (20); a valve seal piece (42) located around the main valve (40) and preventing the passage of compressed air from the barrel (30) side into the back pressure zone (Abb); and an internal filling valve (54) controlled by an internal valve cover (56) which opens when the main valve (40) comes to an open position (Ak) with the opening direction movement (Ayh), allowing compressed air to be refilled into the back pressure zone (Abb) from the filling tube (20) and the main valve (40) to return to the closed position (Kk).
