Abstract: A damper includes a pressure tube, a piston assembly, a piston rod, a reserve tube, and a reserve chamber. The damper also includes a base valve assembly having a valve body and a compression disc assembly. The compression disc assembly engages a first end face of the valve body to restrict flow through at least one compression passage. The base valve assembly also includes a rebound disc assembly. The rebound disc assembly engages a second end face of the valve body to restrict flow through at least one rebound passage. The rebound disc assembly includes at least one rebound bending disc that directly engages the second end face to close the at least one rebound passage. The rebound bending disc bends in response to pressure within the at least one rebound passage to permit flow through the at least one rebound passage.

Abstract: A valve body for a damper includes a plurality of pressure tubes of the damper having different diameters. The valve body includes a plurality of fluid passages. The valve body further includes a plurality of stepped regions having different diameters relative to a valve axis of the valve body. Each stepped region is configured to be selectively coupled to one of the plurality of pressure tubes having a corresponding diameter.

Abstract: A damper assembly includes an outer tube and an inner tube disposed in the outer tube defining a reserve chamber. The inner tube defines an inner volume. A piston is slidably disposed in the inner tube and divides the inner volume into a rebound working chamber and a compression working chamber. A rebound valve is fluidly connected to the rebound working chamber and the reserve chamber, and a compression valve is fluidly connected to the reserve chamber and the compression working chamber. A rebound valve connector fluidly connects the rebound valve and the rebound working chamber and a compression valve connector fluidly connects the compression valve and the compression working chamber. The rebound valve connector includes a one-way valve from the reserve chamber to the rebound working chamber and the compression valve connector includes a one-way valve from the reserve chamber to the compression working chamber.
