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: 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.
