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: An injector for injecting a reagent into an exhaust stream includes an outer tube extending through an electromagnet and surrounding an inner tube. A first end of the inner tube is sealingly fixed to an inner surface of the outer tube. A guide member and an orifice plate are each sealingly fixed to the inner surface of the outer tube. A second end of the inner tube is aligned by the guide member. A moveable valve member includes a pintle head guided by the inner surface of the outer tube to align the valve member with an orifice extending through the orifice plate.

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.
