Patent ID: 8066105

Claim:
A hydraulic damper comprising a tube filled with working liquid, a slidable piston assembly disposed inside of the tube and provided with a compression valve assembly and a rebound valve assembly, a piston rod attached to the piston assembly and extending outside the damper along a piston rod axis, a base valve assembly closing an end of the tube and provided with a compression valve assembly and a rebound valve assembly, at least one compression valve system supported on the piston assembly, the compression valve system including at least one substantially thin closing element having an outside diameter less than the inner diameter of the tube and being axially slidable along the piston rod axis, the compression valve system including a spring surrounding the piston rod axis and pressing the closing element against a retainer into an open position, the compression valve system including an abutting surface for establishing a closed position of the closing element, at least one passage for the flow of damping medium in the closed position, and the compression valve system including a sleeve surrounding the spring and interconnecting the compression valve system to the piston assembly for establishing support between the compression valve system and the piston assembly.
