<p>A hydraulic damper of the type including a valve disc deflectable around the inner and outer peripheries thereof to form fluid passages around the outer and inner circumferences thereof when the damper is actuated in opposite directions. A movable valve seat defining an annular valve seat having a diameter intermediate the inner and outer diameters of the valve disc is disposed to cooperate with the valve disc such that the effective pressure receiving area of the valve disc is reduced when the valve disc deflects in one direction and the movable valve seat is movable substantially freely when the valve disc deflects in the other direction.</p> |
