ABSTRACT:
A suspension damper includes a housing bounding a main chamber. A piston rod is slideably disposed within the main chamber of the housing. A main piston is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.
