Abstract

A pneumatique hammer comprises a casing (1), a jacket (2), a handle (10), a striker (3) mounted in the casing (1) with the possibility of axial movement, a working element (6) actuated by the striker (3), an air distributing device (7), a pneumatic shock-absorber (11), a cover (8) with steps (20, 21, 22), and a shock-absorber (13). The pneumatic shock-absorber (11) has cavities (27, 28, 29) and is mounted on the cover (8). The step (20) is provided with a central channel (25) having a variable cross-section. The step (21) has a control throttle (26), which serves to control the pressure in the chambers (27, 28, 29) by connecting them, during the functioning of the hammer, to the pressure line (12) or to the atmosphere through the throttle (26).
