Abstract

The air gun with a gas-driven piston consists of the body (1), barrel (2), cocking lever (3), piston rod (4) and air piston (5), trigger mechanism (7). The piston rod (4) and the air piston (5) are pushed by the gas piston (8) coming out of the gas cylinder (10) linked via the gas channel (13) with the closed cavity (12) containing the gas bulb (17) which releases the gas through the needle (16).

Claims

AMENDED CLAIMS
[recened by the International Bureau on 23 June 1 97 (230697). original claim replaced b\ amended claim ( 1 page)J
The air-gun with a gas-driven piston made up by a body attached to a barrel, cocking lever fitting into an air piston rod, air intake under a bullet, trigger mechanism to release the piston rod and a gas cylinder firmly consolidated in the body and linked with a gas channel with a cavity, with the folowing typical features: the piston rod (4) with the air piston (5) pushes the gas piston (8) provided with the packing (9) and inserted in the gas cylinder (10) while the cavity (12) inside the breech piece (11) attached to the gun is designed to accommodate the gas bulb (17) and closed with the lid (14) with the sealing (15) and the cavity (12), preferably on its lid (14), contains the needle (16) to pierce the gas bulb (17).
