The disclosed cover comprises a substantially cylindrical hollow body (2), an elastic compensating membrane (3) and a compensating spring (16). The hollow body (2) has at one of its ends (C) an inlet to which is coupled the functional extremity (5) of a hydraulic cylinder (C), and at the other end a closure face (10). The membrane (3) has a retaining extension (9) for its secured positioning and prevents the liquid (F) contained in the cylinder (C) to leak to the outside. The helical spring (16) actuates permanently in a compression mode and one of its ends bears against the inside of the closure face (10) while its other end bears against the internal face (9) of the membrane (3). The membrane (3) and the hollow body (2) define a compensation chamber (15) whose volume (VC) varies as a function of the pressure exerted by the fluid (F) on the external face (8) of the membrane (3). Application to the motor vehicle industry. <IMAGE> |
