Abstract

A compression-vacuum action percussive machine comprises a casing (1), a drive (2) secured inside the casing (1), a pick tool (3), and a cylinder (4). The cylinder (4) accommodates a piston (5) connected to the drive (2), and a hammer (6) engageable with the pick tool (3). The machine also comprises a means for trapping the hammer (6) for the machine to idle, this hammer trapping means being part of the cylinder (4) secured inside the casing (1). The trapping means has an axial clearance (12) and a radial clearance (11) relative to the casing (1) to define a free end of the cylinder (4) having section (13) of a diameter substantially smaller than the diameter of the hammer (6). Longitudinal slots (14) divide the wall of the cylinder (4) into resilient lobes (16) which constitute the trapping means. The invention provides reliable trapping of the hammer (16) when changing from working to idling, in the normal working position or in the <IMAGE>
