Abstract: A shock absorber has a housing with a piston rod assembly disposed therein. A first rod guide member is secured within a first portion of the housing so as to be concentrically disposed about at least a portion of the piston rod assembly. A second rod guide member is secured within the housing adjacent the first rod guide member so as to be concentrically disposed about at least another portion of the piston rod assembly. An electronically controlled valve assembly is disposed within the second rod guide member and is in communication with the first rod guide member.

Abstract: A shock absorber includes a pressure tube, a rod, a rod guide, a first piston, a second piston, and a cup. The pressure tube has an inner surface that defines a fluid chamber. The rod extends into the pressure tube. The rod guide locates the rod relative to the pressure tube. The first piston is coupled to the rod and divides the fluid chamber into an upper working chamber and a lower working chamber. The second piston is coupled to the rod and disposed within the lower working chamber. The cup has an open end configured to receive the second piston and a closed end opposite of the open end. The cup includes a sidewall and a bottom wall. The sidewall includes a cylindrical section and a flared section. The bottom wall forms the closed end of the cup, extends radially outward of the sidewall, and supports the pressure tube.

Abstract: A shock absorber is disclosed which has a base valve assembly for controlling a flow of a working fluid between a reservoir chamber and a working chamber of the shock absorber. The base valve makes use of at least one digital valve assembly. The digital valve assembly communicates with an intermediate chamber formed between an intermediate tube and a pressure tube of the shock absorber. The digital valve assembly controls flow of the working fluid between the intermediate chamber and the reservoir chamber, to help control a damping action provided by the shock absorber.

Abstract: A shock absorber with a pressure tube, a reserve tube, and a piston slidably disposed within the pressure tube to define first and second working chambers. A reservoir chamber is positioned between the pressure tube and the reserve tube. A damper baffle tube, positioned in the reservoir chamber, defines a baffle tube chamber between the pressure tube and the damper baffle tube. One or more electromechanical valves are positioned in fluid communication with the first working chamber and the baffle tube chamber. The damper baffle tube includes a compliant portion that has a sealing surface configured to move into and out of contact with the pressure tube in response to fluctuations in fluid pressure in the baffle tube chamber so as to form a check valve that holds a constrained volume of hydraulic fluid in the baffle tube chamber.

Abstract: A damper having a pressure tube, a piston, and a hydraulic compression stop assembly. The piston is arranged in sliding engagement inside the pressure tube. The piston divides the pressure tube into a first working chamber and a second working chamber and the piston is coupled to a piston rod that extends through the first working chamber. The hydraulic compression stop assembly is positioned in the second working chamber. The hydraulic compression stop assembly includes a sleeve, a plunger, a biasing member, and a pressure relief valve. The plunger is arranged in sliding engagement with the sleeve and can therefore move between an extended position and a retracted position. The biasing member biases the plunger towards the extended position and the pressure relief valve relieves excessive fluid pressure inside the hydraulic compression stop assembly.

Abstract: A shock absorber is disclosed having a pressure tube forming a working chamber, and a piston assembly slidably disposed within the pressure tube. The piston assembly may divide the working chamber into upper and lower working chambers. The piston assembly may have a piston body defining a first fluid passage extending therethrough and a first valve assembly controlling fluid flow through the first fluid passage. A second fluid passage, separate from the first fluid passage, extends from one of the upper and lower working chambers to a fluid chamber defined at least in part by the pressure tube. A plurality of digital valve assemblies are included and configured to exclusively control all fluid flow through the second fluid passage, and thus all fluid flow between the one of the upper and lower working chambers to the fluid chamber.

Abstract: The present disclosure relates to a shock absorber having a pressure tube which defines a fluid chamber, and a piston assembly. The piston assembly is disposed within the fluid chamber and divides the fluid chamber into upper and lower working chambers. A reserve tube surrounds the pressure tube to define a reservoir chamber between the reserve tube and the pressure tube. The pressure tube is disposed between a rod guide assembly and a lower mount. A structural integrity of the pressure tube is greater than a structural integrity of the reserve tube, and the pressure tube further operates as a principal load bearing component for the shock absorber.
