Abstract
The machine comprises a housing (1) in which is disposed for axial reciprocation a hammer (2) defining a front working chamber (4) and having a through radial passage (3). In the cavity of the hammer on the side of its tail end there is a cylindrical stepped tube (5) which includes first and second steps having through radial passages (9,10). The first step (6) defines with the hammer a rear working chamber (12), and with the second step (7) defines an annular cavity (13) in which a spring-loaded sleeve (14) capable of axial displacement is disposed. The outer diameter of the sleeve is less than the inner diameter of the first step, to form therebetween an annular passage (15).
