Abstract (en)
[origin: WO2020193883A1] Hydraulic suspension damper comprising a damper piston which slides in an internal tube (2) and which is displaced during compression of the damper in an axial direction referred to as the forward direction, the damper piston being extended by a stop piston (10) which enters, at the end of travel of the damper, a stop chamber (16) which is provided with bores (18), forcing the fluid out of this stop chamber (16) in order to brake the travel end, the stop chamber (16) comprising a lateral bore (44) which is arranged after a predefined travel (C0) of the stop piston (10) in the stop chamber (16), and which is provided with a valve (34) for limiting the pressure in this stop chamber (16).
