A damper assembly includes a housing having a tubular shape defining a main chamber extending along a center axis. A piston is movable along the center axis and divides the main chamber into a compression chamber and a rebound chamber. The piston includes a piston body defining a frequency-adaptive orifice (FAO) passage providing fluid communication between the compression chamber and the rebound chamber. The piston includes an FAO valve assembly having an FAO cover member configured to block fluid flow therethrough in response to application of a low-frequency excitation, and allowing fluid flow through the FAO passage in response to application of a high-frequency excitation. The FAO valve assembly also includes a tappet configured to translate relative to the piston body to bias the FAO cover member to selectively cover the FAO passage in response to the application of the low-frequency excitation.

An air management module for use in a vehicle suspension system, the module including a plurality of inlets, outlets, and control valves and a manifold. The plurality of inlets configured to receive compressed air from a vehicle air compressor and the plurality of outlets configured to provide the compressed air to the outlets. The control valves configured to receive the compressed air from the inlets and selectively provide the compressed air to the outlets. The manifold including a plurality of wall members layered on top of one another, each wall member defining a plurality of apertures, some of the apertures collectively forming a plurality of passages configured to direct the compressed air from the plurality of outlets to the plurality of inlets.

A sensor assembly configured for use in a vehicle suspension system. The sensor assembly including a main body, a nose, a first sensor, and a second sensor. The main body defining a first receptacle and including a first end and a second end. The nose extending from the main body and defining a second receptacle. The first sensor disposed in the first receptacle and configured to measure a first vehicle characteristic of the vehicle suspension system. The second sensor disposed in the second receptacle and configured to measure a second vehicle characteristic, and the second vehicle characteristic being different than the first vehicle characteristic.

In general terms, this invention provides a twin-tube damper having an outer and inner tube creating a chamber between the inner and outer tubes for oil. A piston and rod move within the inner tube in response to driving conditions. A base valve assembly is positioned between the inner tube and outer tube. The base valve assembly includes a cylinder end with a first end and a second end. Openings extend through the cylinder end and are in fluid communication between the inner tube and the outer tube. The base valve assembly first end defines a seal surface and an intake disc is mounted adjacent the seal surface. The seal surface has a lowered section. A compression relief valve assembly is positioned adjacent the second end. When pressure is low in the inner tube, the gap between the seal surface and the intake disc allows additional oil flow paths through the base valve assembly. The gap is incrementally closed by the intake disc when pressure increases in the inner tube.
