Abstract
A damper system for a vehicle is provided that includes including a pressure tube, a piston rod, and a piston assembly that is mounted to the piston rod and separates the pressure tube into first and second working chambers. A valve assembly, mounted to the piston assembly, controls fluid flow between the first and second working chambers. A frequency dependent damper assembly, coupled to the piston rod at a position below the piston assembly, includes a plunger sleeve that is longitudinally moveable to transmit an adaptive force to a valve assembly. A plunger travel limiter, positioned longitudinally between the frequency dependent damper assembly and the valve assembly, contacts the plunger sleeve and prevents the plunger sleeve from moving further towards the piston assembly to limit the magnitude of the adaptive force applied to the valve assembly.
