Patent ID: 7896142

Claim:
A shock absorber comprising: a pressure tube defining a fluid chamber; a piston assembly disposed within said fluid chamber, said piston assembly dividing said fluid chamber into an upper working chamber and a lower working chamber; a piston rod attached to said piston assembly, said piston rod extending from said piston through one end of said pressure tube; and a dynamic vibration absorber attached to said piston rod, said dynamic vibration absorber including a retention mechanism engaging said piston rod, a damping mass and an elastomeric member disposed directly between said damping mass and said retention mechanism, direct contact between said damping mass and said retention mechanism being prohibited by said elastomeric member, said damping mass being a cup-shaped element having a bottom engaging said elastomeric member and an annular wall attached to said bottom, said engagement between said bottom and said elastomeric member being the only attachment of said damping mass to a component of said shock absorber, wherein said retention mechanism comprises: a cap attached to said piston rod; and a retainer attached to said cap; wherein said damping mass is attached to said cap; and said elastomeric member comprises: a first elastomeric mount disposed between said retainer and said damping mass; and a second elastomeric mount disposed between said damping mass and said cap.
