Abstract

Hydropneumatic shock absorber specially used in the bumpers of motor vehicles, of the type comprising a pair of telescopically coupled tubes, each of which is hermetically closed by the end of the device and inside which there is assembled with the possibility of sealed sliding a piston of separation that divides the interior of the device in a gas chamber located between the piston and the cap of the inner tube and an oil chamber divided in turn by a transverse diaphragm with a valve fixed at the end of the inner tube that is inserted in the outer tube, characterized in that the diaphragm with valve is constituted by a rigid disk (30) with a circular series of holes (32) that on its surface (48) on the side of the piston has a plug (34) of the exit of the drills (32) to this surface (48) and that is constituted by a pack of elastic washers (50, 52, 54) fixed in the center of the d isco (30), the diaphragm also having permanently open ducts (64, 66) whose passage section is considerably smaller than the total passage section of the holes (32) disposed circularly.
