Abstract

The invention refers to a pneumatic hammer which has air flow through canals (2) and an outlet hole (3, 4) equipped housing (1) with several collar pieces, which partly contain a tool (5), partly one with the same interacting, with several collar pieces fitting a hammer device (6), partly a return striking area (7), partly a pipe slide valve (8) with hole (9) for compressed air supply and a ring-shaped projection (10), which is designed at the side valve (8) against the return striking area's (7) turned side, and partly a working strike area (11) designed to be continuously fed with compressed air. The hammer is characterized by the pipe slide valve (8) having a housing (12) with air flow through canals (13), hole (14) for compressed air supply and an outlet hole (15), at which the slide valve housing (12) has two ring-shaped hole areas (16, 17) where the hole area (16) with a larger diameter, which is turned toward the return striking area (7), containing the pipe slide valve's (8) ring-shaped projection (10) and has an opening (18),intended to be connected with the air flow through canals (13) and working strike area (11) when a strike is carried out, and with a hole area (17) with a smaller diameter than the pipe slide valve (8) at its movement against the return strike area (7) when it adopts its end position. The hole area (17) with a smaller diameter is connected with the outlet hole (15) in the pipe slide valve housing (12).<IMAGE>
