Abstract
A shock absorber having a cylindrically shaped housing including a piston dividing the housing into a compression chamber and a rebound chamber. The piston presents a plurality of apertures for allowing oil to flow between the compression and rebound chambers. A rebound resilient disc is disposed in the compression chamber for obstructing the flow of oil from the rebound chamber to the compression chamber. A two-spring adjustable valving system is disposed in the compression chamber for extorting a biasing force against the rebound resilient disc. A sleeve extends between the first and second springs to interconnect the first and second springs. An actuator is connected to the second spring through a spindle for selectively compressing or expanding the second spring to adjust the biasing force on the rebound resilient disc.
