Hydraulic suspension dampers with control valve assembly and regulating controls

Abstract

A suspension damper includes a housing bounding a primary chamber and including: an inner sidewall that encircles the primary chamber; an outer sidewall that encircles the inner sidewall so that a bypass channel is disposed therebetween; and a plurality of ports being longitudinally spaced apart along the inner sidewall and extending through the inner sidewall so as to provide fluid communication between the primary chamber and the bypass channel. A main piston having a compression port is disposed within the primary chamber and a control valve assembly is disposed adjacent to the main piston. The control valve assembly includes a valve guide and a control valve with a valve compartment bound therebetween. The control valve assembly is movable between a first position where the control valve is positioned toward the main piston and a second position wherein the control valve is moved away from the main piston.
