Abstract
A shock absorber has a rebound stop assembly. The rebound stop assembly is mounted to the piston rod and includes an outer housing assembly slidably disposed within the working cylinder of the shock absorber and an inner housing member secured to the piston rod and slidably disposed in the outer housing member. The housing members define a damping chamber therebetween for receiving damping fluid therein. The rebound stop assembly also includes a damping device associated with the inner and outer housing members for creating a damping force in the shock absorber after a predetermined amount of rebound stroke of the piston within the working cylinder. A restrictive passage controls the flow of fluid from the damping chamber and this restrictive fluid flow provides additional damping at the end of the rebound stroke.
