Abstract

1. Impact and drilling device, which is operated by means of pressure liquid, in particular water under high pressure, and having an outer, rearward stationary part (1, 53), provided with a pressure liquid supply line line (2, 2') as well as an inner, moveable part (10), which bears an impact and drilling tool (18, 19) at the front end, with a main control valve (7) for the hydraulic control of a swinging movement of the moveable part, designed as a percussion piston (10), and with a pilot valve (50) for the hydraulic control of the main control valve (7), which pilot valve is for its part controlled by the swinging movement of the percussion piston (10), there being recoil jets (4) or a linkage for the advance arranged at the rear end of the stationary part (1, 53), characterised in that the pilot valve (50) and the percussion piston (10) are pushed into one another in the region of a neck on the percussion piston (10) and form a control chamber (21'), in that a thrust shoulder (25) is arranged on the pilot valve inside the control chamber (21'), and in that a displacement of the percussion piston (10) opens a control bore (21), radially arranged in the pilot valve (50) and serving to pressurize the control chamber (21') and closes a bore (24) serving to vent the chamber, or, in the case of an opposed displacement, closes and opens these bores respectively.
