The gas distributor, comprising a cylinder (1) and a sliding piston (8) with a head (11), a compressed gas inlet (14) and a chamber, is designed to provide automatic forward movement of the piston, allowing compressed gas into the chamber, recoil and return of the piston, closing the compressed gas inlet, release of residual gases in a forward direction and return of the piston to its initial position. The distributor has a valve (5) and a double seal (3) for opening the compressed gas inlet, each with a return spring (6, 4). |
