Abstract

A sealing arrangement in percussion apparatus includes an annular seal (20) acting between a tube (6) for a flush medium and a wall of a flush channel (16), which receives the free end of the tube (6) and is located in an insert end (9) of a percussively operating tool and a guide element (19) arranged between the tube (6) and the wall of the flush channel (16). <IMAGE>
