Abstract: A shock absorber for a vehicle includes a pressure tube that defines a fluid chamber. A piston disposed within the fluid chamber divides the fluid chamber into an upper working chamber and a lower working chamber. The piston defines a compression passage and a rebound passage which extend through the piston between the upper working chamber and the lower working chamber. A valve disc assembly engages the piston and controls the flow of fluid between the upper working chamber and the lower working chamber. The valve disc assembly includes a bleed disc that defines an orifice with a substantially non-linear contour. The orifice extends to an outer diameter of the bleed disc, and forms a bleed channel between the upper working chamber and the lower working chamber.

Abstract: A shock absorber includes a pressure tube forming a working chamber. A reserve tube is concentric with and radially outward from the pressure tube. A baffle tube is positioned radially outward from the pressure tube. A reservoir chamber is formed between the reserve tube and the baffle tube. A piston is attached to a piston rod and slidably disposed within the pressure tube. A rod guide is attached to the pressure tube and supports the piston rod. An electromechanical valve is positioned within the rod guide. The baffle tube and the pressure tube form a fluid passage between the electromechanical valve and the reservoir 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 damper system and method for a vehicle includes a shock absorber and a damper module. The shock absorber includes a plurality of digital valves. The shock absorber is operable at one of multiple damping states based on a valve state of the digital valves. The damper module is coupled to each of the digital valves and controls each of the digital valves to a desired state based on a damper setting. The damper module determines a target damping state, where the target state is one of the multiple damping states. The damper module performs a switch operation to control the valve state of the plurality of digital valves to a given desired state when the target damping state is different from a present damping state.

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 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.
