Abstract
Official abstract text for this publication.
A damper assembly for a vehicle suspension system includes a damper and a valve block coupled to the damper. The damper includes a tubular sidewall having an inner surface that defines an inner damper volume and a plunger separating the inner damper volume into a compression chamber and an extension chamber. The valve block includes a housing having a spring pilot and defining a flow path between an inlet port and an outlet port. The inlet port is in fluid communication with at least one of the compression chamber and the extension chamber. The damper assembly further includes a flow controller coupled to the housing and positioned along the flow path and a piston having a pilot end coupled to the spring pilot and an interface end that engages the flow controller with a pilot force that varies based on a pressure at the spring pilot.
