Abstract

An arrangement in motor driven percussion tools, preferably rock drilling machines driven by internal combustión engines, comprising a piston 1 of the engine that can move a cylindrical chamber and that drives, an impact piston 2 by means of a mass of gas 5 located in the cylindrical chamber and in which is arranged a connecting channel 12 provided with a check valve 11, between the cylindrical chamber and a second chamber 10 located on the side of the cylindrical chamber furthest from the impact piston, characterized in that the second chamber 10 communicates by means of a conduit or passage with an expansion chamber located inside the impact piston, and in that the mass of gas enclosed in the second chamber and expansion chamber forms a gas absorber that provides the mobile having a diameter that is greater than the diameter of the return stroke of the impact piston.
