<p>The invention concerns a end-of-stroke hydraulic bumper stop for a damping system comprising a limit stop piston (10) integral with a cylinder rod (7) sliding in the damper body (1), including also a limit stop body (120) fixed at the upper end of the body (1), a cylindrical portion (103) of the limit stop piston (10) being urged to enclose and compress an oil volume (V) contained in an inner housing (12) of the limit stop body (120) upon compression displacement of the damper. A fraction of the oil volume (V) flows back between the piston (10) and the limit stop body (120), said fraction decreasing with the forward displacement of the limit stop piston (10), thereby generating a resistance to the increasing compression, as well as forming a high pressure oil film (F) between the piston (10) and the limit stop body (120) which lubricates the contact between the surfaces of those two components.</p> |
