Abstract
An arrangement of percussion motor tool comprising a main body having an upper cylinder and a lower cylinder, an upper piston and a lower piston adjusted in both cylinders cited respectively, and connected with a piston rod, a chisel arranged under the body main, against the upper end of which hits the lower end of the lower piston when both said pistons are lowered, a main valve to open and close the oil inlet hole and the outlet of the oil taken to the oil chamber in the lower part inside said lower cylinder, and a limiting valve moved by pressure by the rising upper piston, and wherein the operating part of said main valve and the limiting valve are mutually related so that the main valve can disconnect the oil chamber and the oil inlet hole and communicate the oil chamber and the orifice or oil output by feeding the compressed gas at high pressure in the upper chamber inside the upper cylinder to the operative part of the main valve when the imitating valve is moved under pressure by the upper piston, and the oil chamber is put in communication and the inlet hole for the same and the oil chamber and the outlet for the oil are disconnected during the time that the limiting valve, is not moved under pressure by the upper piston, and when the oil chamber is put into communication with the oil inlet hole, the lower piston must be pressed up by the pressurized oil fed into the oil chamber from the oil inlet hole.
