Abstract

See full text

A damper system for a vehicle is provided that includes a pressure tube and a piston assembly separating the pressure tube into first and second working chambers. A frequency dependent damper assembly, coupled to a piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a first valve assembly mounted to the piston assembly. The frequency dependent damper assembly includes first and second accumulation chambers that are separated by a floating piston. A second valve assembly, carried on the floating piston, controls fluid flow between the second accumulation chamber and the second working chamber. A bleed channel in the floating piston allows fluid flow between the first and second accumulation chambers, which reduces the adaptive force the plunger sleeve applies to the first valve assembly during high frequency, low velocity rebound inputs.
