Abstract
A shock absorber includes a rebound valve assembly which performs the flexing disc function normally required for allowing the passage of fluid from one side of a piston assembly to the opposite side during the stroke of the shock absorber. The rebound valve assembly also incorporates a blow off function which increases the fluid flow through the piston when the fluid pressure being exerted upon the rebound valve assembly exceeds a specified level. The blow off feature utilizes a coil spring to protect both the shock absorber as well as the suspension system into which the shock absorber is assembled.
