Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. The piston assembly includes a frequency dependent valve assembly attached to the piston rod which defines a housing attached to the piston rod and a spool valve assembly. The spool valve assembly includes a spool valve and a bypass valve assembly that controls fluid flow through bypass passage that bypasses the piston assembly.

Abstract: A valve assembly for a damper is provided. The valve assembly includes a housing defining a fluid cavity. The valve assembly includes a spool valve movably disposed within the housing. Further, the valve assembly includes a bumper disposed between the housing and the spool valve. At least the bumper, the spool valve and the housing together define an enclosed volume. The valve assembly further includes one or more bleed paths defined on at least one of the bumper, the spool valve and the housing, the one or more bleed paths fluidly communicating the fluid cavity with the enclosed volume.

Abstract: A shock absorber has a pressure tube with a piston assembly slidably disposed within the pressure tube and attached to a piston rod. The pressure tube is disposed within a reserve tube and a working fluid reservoir is formed between the pressure tube and the reserve tube. The piston assembly divides the pressure tube into an upper working chamber and a lower working chamber. A base valve assembly controls a flow of working fluid between the working fluid reservoir and the lower working chamber. The base valve assembly includes a frequency dependent valve system that provides an increased level of damping for each compression stroke of the piston assembly during low frequency movements of the shock absorber. A lesser level of damping is provided for each compression stroke during high frequency movements of the shock absorber.
