Abstract
An axially reciprocable rotary spindle is mounted in the housing, and a first biasing arrangement urges the spindle in one axial direction outwardly of the housing. An impact member is mounted on this spindle for rotation with but limited axial displacement relative to the same and has an outer circumferential surface provided with cams inclined axially and circumferentially of the spindle and formed with one interruption per cam. A second biasing arrangement urges the impact member also in the aforementioned axial direction, and a fixedly mounted guide ring surrounds the impact member and forms a race for roller bodies corresponding in number to the interruptions and which roll in contact with the circumferential surface and the cam.
