Abstract: An automatic functioning device for distributing compressed gas comprises a jack and a distributor. The device successively and automatically carries out the following operations, after the piston has been initially hit on its rear end by a hammer: forward piston displacement, compressed gas intake into the chamber and pressurization of the latter; recoil of the piston to the rear, escape of compressed gas contained in the chamber and depressurization of the latter; return of the piston to the front, closing of the compressed gas intake, escape to the front of the remaining compressed gas contained in the chamber and return of the device to its initial position.
