Abstract

A telescopic hydraulic shock absorber of the type comprising a cylinder, inside which a sliding piston is mounted, having a rod projecting from the cylinder through an annular head, characterized in that inside the cylinder (12) and close to the head (14), there is a bushing (25, 26a) that limits a longitudinal passage for the hydraulic fluid contained in the cylinder (12); because, interposed between the bushing (26, 26a) and the head (14), there is a helical compression spring (28, 28a), and because on the rod (16) there is a thrust ring (18), towards the at the end of the extension stroke of the shock absorber, it abuts the bushing (26, 26a) and pushes it towards the head (14), overcoming the force of the spring (28, 28a) and closes, at least partially, the passage longitudinal (30), providing means of limiting the stroke of the bushing (26, 26a) towards the piston in a position of distension of the coil spring (28, 28a).
