Abstract
A shock absorber including a damper and a valve assembly for throttling fluid flow between a compression damper chamber and a pneumatic spring, with a valve assembly extending from an inner end portion of the damper into the compression damper chamber along a longitudinal central axis of the damper. A piston assembly is provided that includes an inner space which is open to the compression damper chamber and configured to receive and sealingly engage a distal portion of the valve assembly at an inner operational range of stroke and to disengage the valve assembly upon movement outside the inner operational range of stroke. The sealing engagement between the distal portion of the valve assembly and the inner space divides the compression damper chamber into an inner volume within the inner space and an outer volume in front of the piston assembly.
