Claim 9:
10. A damper comprising:
a pressure tube extending annularly about a damper axis;
a piston arranged in sliding engagement inside said pressure tube;
said piston dividing said pressure tube into a first working chamber and a second working chamber;
a piston rod coupled to said piston;
a hydraulic compression stop assembly positioned in said second working chamber, said hydraulic compression stop assembly including a sleeve, a plunger arranged in sliding engagement with said sleeve for movement between an extended position and a retracted position, and a biasing member that biases said plunger towards said extended position;
said plunger extending longitudinally between a first plunger end that is configured to contact at least one of said piston and said piston rod during a compression stroke and a second plunger end that is arranged in sliding engagement inside said sleeve; and
said first plunger end including a bumper cavity that receives a bumper made of a compliant material, said bumper cavity including a side wall and said bumper having an outer circumferential surface that abuts said side wall of said bumper cavity, wherein said outer circumferential surface of said bumper, in an uncompressed state, is arranged at a non-parallel angle relative to said side wall of said bumper cavity to create radial compression in said compliant material of said bumper and an interference fit between said outer circumferential surface of said bumper and said side wall of said bumper cavity that operates to prevent movement of said bumper relative to said side wall of said bumper cavity during movement of said piston within said pressure tube.
