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 includes a pressure sensitive valve assembly that controls fluid flow through the pressure sensitive valve assembly based upon the velocity of the piston assembly in the shock absorber. The pressure sensitive valve assembly restricts fluid flow as the velocity of the piston in a compression stroke increases to increase the damping loads provided by the shock absorber. A secondary valve assembly controls fluid flow through the pressure sensitive valve assembly when the pressure sensitive valve assembly is in a closed position.

Abstract: A shock absorber has a compression valve assembly that provides a high damping load during a compression stroke and an extension valve assembly that provides a high damping load during an extension stroke. One or more digital valve assemblies is positioned to work in parallel with the compression valve assembly and the extension valve assembly to provide a lower damping load. The lowering of the damping load is based upon the cross sectional area of flow passages provided by the one or more digital valve assemblies.

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.
