DAMPER ASSEMBLY WITH CLAMPED FREQUENCY DEPENDENT VALVE

A damper assembly includes a damper tube extending along a center axis and defining a fluid compartment. A piston is attached to a damper rod and divides the fluid compartment into a compression chamber and a rebound chamber. The piston includes a piston body and a frequency-dependent (FD) valve. The piston body defines an intermediate chamber in fluid communication with the rebound chamber. The FD valve includes: an FD housing having a tubular shape surrounding an FD chamber, an FD slider disposed within the FD housing and dividing the FD chamber into an FD pressure chamber and an FD displacement chamber, an FD control stack configured to regulate fluid flow between the intermediate chamber and the FD pressure chamber, and an FD working disc configured to deflect together with the FD housing for regulating fluid flow between the rebound chamber and the compression chamber.
