Abstract

A double-tube hydraulic shock absorber in which there is an outer cylinder and an inner cylinder between which a cavity is formed, with a piston slidable in the inner cylinder, which is provided with a stem which, in operation, protrudes from the upper end of the shock absorber through an annular head common to both cylinders, this head having an axial hole extending from the interior to the exterior of the damper, and which has a part of a smaller diameter housing a bushing in which it can slide the piston rod and a part of larger diameter acting as a collection sump for the hydraulic fluid that is extracted between the rod and the hub of the inner cylinder cavity, characterized in that between the bushing (30) and the annular head (14) there are formed longitudinal conduits (32) that allow the upward passage of air from the cavity (20) to the sump (28).
