Hydraulic damper with adjustable rebound valve assembly
Abstract:
A hydraulic damper (1) includes an orifice plate (33) provided with an axial projection (334) and a number of rebound flow passages (332) disposed around the projection (334). A deflectable disc (91) and an elliptical disc (92) is disposed slidably one on top of the other over the axial projection (334) to cover a compression side of the rebound flow passages (332). A cage member (34) is fixed to a piston assembly at the compression side thereof and is provided with at least one passage (341, 343). A compression spring (95) is preloaded between the cage member (34) and the discs (91, 92) to normally close the compression side of the rebound flow passages (332).
