Abstract

A telescopic hydraulic shock absorber of the type comprising a cylinder housing a sliding annular piston in which, interposed between the cylinder and the piston, there is a cut ring of rectangular section, of a plastic material of low coefficient of friction, which is housed in an annular slot with a cylindrical bottom milling on the periphery of the piston, characterized in that the sides (28) of the groove (20) are divergent, radially outwardly and the width (a) of the ring (22), in the axial direction of the piston (14) is of an intermediate value between the maximum and minimum distance of the sides (28).
