Abstract

A pressure medium operated reciprocating impact mechanism has a working member (7) and a stop member (15), which are axially movable with respect to each other, and a working chamber (22) for pressure medium is arranged in at least a first one of them and is open towards the other member. A sealing member (21) is arranged inside the working chamber between the working member and the stop member and to bear radially against the circumferential wall (14) of the working chamber and seal the working chamber in that position of the relative movement of these members in which they are brought most together. The sealing member is adapted to, on movement of the working member and the stop member apart starting from said position and caused by action of the pressure medium entering into the working chamber, move axially with respect to one of these members while bearing sealingly against the circumferential wall (14) of the working chamber and axially sealing the working chamber to the other of these members. One of the working and stop members has means (25, 29) adapted to allow the pressure medium to escape out of the working chamber when the other of said members has reached a position located at a predetermined distance from the position thereof in which said members are brought most together.
