ABSTRACT VALVE ASSEMBLY AND REDUCED HARSHNESS SHOCK ABSORBER EMBODYING THE SAME. A shock absorber including a piston assembly dividing a cylinder into a rebound chamber and a com- pression chamber, the piston assembly including fluid control bleed orifices of a size to permit flow there- through during a relatively slow long amplitude movement of the piston assembly in either direction, normally closed valves for controlling the flow of fluid between the chambers during relatively fast long amplitude movements of the piston assembly, and a normally open valve assembly operable (1) to permit relatively unrestricted flow of hydraulic fluid between the chambers during a relatively rapid short amplitude movement of the piston assembly in either direction and (2) to move into a closed position (a) during a relatively slow long amplitude movement of the piston assembly in either direction so as to permit the bleed orifices to control the resultant fluid movement between the chambers and (b) during a relatively rapid long amplitude movement so as to permit the normally closed valves to control the resultant fluid movement between the chambers.
