Abstract (en)
[origin: EP0560512A1] A rotary hammer with a pneumatic hammer mechanism, the ram (25) of which, to generate impacts acting on the hammer bit (11) arranged in a tool holder (10), is moved by a driven reciprocating piston (22), the paths of the reciprocating movement of ram and piston lying on a common straight line (50) and the hammer bit (11) being held coaxial to the tool holder axis in the tool holder (10), has an area (24) of its piston lying eccentric to the tool holder axis (50), said area being moved along an endless orbit about the tool holder axis when the piston is driven. The orbit, which has one point at a minimum and one point at a maximum distance from the tool holder (10), is inclined to the tool holder axis (50). <IMAGE>
