Abstract

A pneumatic percussion machine comprises a barrel (1) with an exhaust opening (9) and a striker (6), movable in the barrel (1) and dividing the barrel's hollow into an idle stroke chamber (8) and a working stroke chamber (7), an air-distributing device, containing a valve box (12) and a valve (13). The valve box (12) contains inside an intermediate element (19) provided with an axial opening (22) and a channel (23) open to the atmosphere. The valve (13) is shaped as a hollow piston, its skirt (28) having a through radial opening (27) connecting periodically, upon operation of the valve (13), the working stroke chamber (7) with a source of compressed air and, through channels (23 and 26) in the intermediate element (19) and the barrel (1), respectively, with the atmosphere.
