Abstract

A signal device for the generation of a seismic pulse, comprising an elongated tubular unit to be fitted in a borehole and consisting of a hammer part (27) and a clamping part (16), said hammer part (27) comprising a hammer (29) for hitting a striking head (28) and said clamping part (16) comprising at least on expander plate (19) extending hydraulically from the wall of said device and serving to lock the device in a borehole at a desired level. Said hammer part (27) is provided with a double-action hydraulic piston (47) whose rod (46) has mounted on its free end a locking bell (37, 38), which during the stroke of piston (47) engages with the hammer pin (32) of said spring-loaded hammer (29) and towards the end of the piston return movement disengages from said hammer pin.
