    摘要： An improved magnetorheological fluid damper is provided which effectively provides a smooth transition, without a sharp break in the damper force/velocity curve, between very low damping forces near zero damper velocity to higher damping forces at higher piston velocities while maintaining desirable maximum force levels. The damper includes a piston assembly, including a magnet assembly and a flow gap extending through the piston assembly to permit fluid flow between the chambers. The force/velocity optimization feature includes a groove or passage open to the flow gap, positioned in series with a part of the flow gap in a magnetic circuit generated by the magnet assembly and dimnensioned/sized to permit fluid flowing through the passage to experience a magnetorheological effect less than a magnetorheological effect experienced by fluid flowing through the flow gap but not through the groove. Preferably, the passage is formed in an inner annular surface of a flux ring positioned around a piston core. The passage may be formed, for example, by a curvilinear surface, a modified rectangular surface or a triangular surface.

    摘要： A rotary damper for use in an automotive vehicle. The rotary damper includes an outer casing having a main chamber and a pair of piston orifices, the main chamber and the piston orifices being filled with a damping fluid, a pivotable cam located in the main chamber and attached to an arm for transferring the rotary movement of the arm to the cam. The damper also includes a pair of pistons, each located in its own orifice, and connected to opposite sides of the cam. When the ami transfers the rotary movement to the cam, each piston is moved in opposite directions in its respective piston orifice to damp the rotary movement of the arm.

    摘要： A magnetorheological damper includes a cylinder and a magnetorheological piston. The magnetorheological piston is located within and slideably engages the cylinder. The magnetorheological piston includes a magnetically energizable passageway and a magnetically non-energizable passageway spaced apart from the magnetically energizable passageway. The magnetorheological piston also includes a pressure and flow control valve disposed to allow pressure-dependent fluid flow in the magnetically non-energizable passageway when the magnetorheological piston slides towards the first end of the cylinder.

    摘要： A damper with continuously variable rates in both extension and compression operation is provided. The damper includes a single tube carrying a piston having at least one pressure chamber and separating the tube into extension and compression chambers. A bi-directional control valve is carried by the piston. The control valve includes a first annular disc carrying a seal and separating the pressure chamber from the extension chamber. A second annular disc carrying a seal separates the pressure chamber from the compression chamber. The discs are variably deflectable under fluid force to provide an opening through the piston. A pair of armatures control the fluid pressure in the pressure chamber to change the deflective characteristics of the discs by varying a backpressure in the pressure chamber. A coil is positioned near the first and second armatures and is operable to draw both the first and the second armatures to close the passages.

    摘要： A rebound cutoff feature is provided for a strut-type suspension damper which includes a hydraulic stop feature in combination with a mechanical stop to limit rebound travel. The strut's piston rod carries a valve collar which interacts with the sole flow passage between the compression and rebound chambers of the strut to hydraulically decelerate movement as the rebound travel limit of the strut is approached.
