摘要： A magnetorheological (MR) damper includes a damper tube, a movable non-MR damper piston, and a non-movable MR damper piston. The damper tube has substantially hermetically separated first and second chambers, wherein the first chamber contains a non-MR fluid and the second chamber contains an MR fluid. The non-MR damper piston is located in the first chamber and is slidable with respect to the damper tube. The MR damper piston has a longitudinal axis and an electric coil, is located in the second chamber, and is fixedly attached to the damper tube. Sliding the non-MR damper piston with respect to the damper tube causes movement of at least some of the MR fluid longitudinally past the electric coil.

摘要： A suspension damper assembly capable of adjusting the height of an automobile includes a cylinder tube defining a pumping chamber aligned concentrically within a reservoir tube. A fluid reservoir is defined between the reservoir tube and the cylinder tube. A piston is slideably disposed within the cylinder tube. A gas cup is slideably disposed within the assembly and separates a fluid chamber within the cylinder tube from a gas chamber. The gas cup includes a cup conduit connecting the pumping chamber to the reservoir chamber whereby stroking the gas cup pumps fluid into the pumping chamber increasing the outward force of the piston for raising the height of the vehicle. A piston shaft guide includes a shaft valve allowing fluid to pass from the pumping chamber to the reservoir chamber for reducing the outward force of the piston and lowering the height of the vehicle.
