Abstract

Percussive worktool. The device comprises a head (12) having a bore (20): - connecting with two chambers (14, 15), - containing a piston (30) which is free with respect to the bore and comprising a radial opening (33) capable of coinciding with one or the other of two recesses (25, 26) inside the bore (20) and respectively connecting with the chamber (15) and with the exhaust (7). Application to barker devices. <IMAGE>
