Abstract: An adjustable vehicle suspension strut configured to be arranged between a wheel assembly and a body of a vehicle, the adjustable strut including a tube. A piston is slidably carried in the tube on a piston rod. A coil is carried on the piston adjacent a first flow passageway in the piston to produce a magnetic field thereacross and a control valve is carried on the piston controlling fluid flow through a second flow passageway in the piston. The control valve is positioned at the distal end of the rod upstream of the first flow passageway.

Abstract: The invention provides a vehicle damper assembly and a method for modulating fluid flow through the same. The assembly includes a housing including a fluid carried therein. A piston is slidably carried in the housing and includes a ring and a core. At least one gap to allow fluid flow is formed between the ring and core. A rod is operably attached to the piston. The ring moves axially with respect to the core to vary the gap size and modulate fluid flow during operation of the assembly. The method includes axially moving a ring with respect to a core during assembly operation. At least one gap size is varied based on the axial movement, wherein the gap is formed between the ring and core.

Abstract: A damper for dampening vibrations of a rotatable steering shaft of a motor vehicle comprises a rotor and means for rotating the rotor at a rate proportional to and greater than rotation of the steering shaft. Magnetorheological fluid is disposed at least partially around the rotor, and has a viscosity variable to vary a load on the rotor.

Abstract: A damper includes a piston that carries a relatively compact control valve for controlling fluid flow through the piston. The control valve provides a variable amount of damping by regulating damper fluid flow between the extension chamber and the compression chamber of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through a flow path as determined by the control valve. The damping force of the damper varies depending upon the loading conditions of the vehicle. The control valve is air pressure actuated to adjust the damping force and control the flow of fluid in the flow path.
