    摘要: A monotube damper valve is provided in a piston (14) with a piston body (26) having an annular bearing (42) and an extension stop surface (52). A piston rod (20) is connected to the piston body. A retainer (39) having a compression stop surface (51) is carried about the piston rod adjacent the piston body. A bearing washing (38) is carried about the piston rod near the retainer. A bi-directional monodisc valve element (40) has an inner perimeter (47) supported by the bearing washer and an outer perimeter (48) supported by the annular bearing in an at-rest condition. During a compression stroke of the piston body, the monodisc valve element is movable to a maximum compression deflected position wherein it is uniformly supported by the compression stop surface. During an extension stroke of the piston body the monodisc valve element is movable to a maximum extension deflected position wherein it is uniformly supported by the extension stop surface.

    摘要: Parallel paths for damping fluid are provided through the piston of a suspension damper, each of which are provided with separate damping valving sets to control damping. Communication through one of the paths is controlled by a movable control valve member, which is controlled by a magnetostrictive element which deforms in response to application of a magnetic field. The control valve member is moved between active and inactive positions in response to changes in a magnetic field applied by a coil mounted within the damper piston. In one position, all communication of damping fluid is through one of the damping valve sets, while in the other positon damping fluid communicates through both valve sets. Accordingly, damping levels may be varied by controlling the magnetic field.

    摘要: A damper (10) includes a piston (22) that carries a relatively compact control valve (26) 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 (18) and the compression chamber (20) of the damper during extension and compression strokes. Pressure regulation across the piston is controlled through a flow path (38) 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. The piston and rod assembly include unique features such as a seal plate (142a) design, and spring retainer (158) that aid in the efficient and reliable assembly in a commercial production setting.

    摘要: The device comprises a cylinder (1) which is divided in two variable volume chambers (3, 4) by a piston (2, 2'), which has conduits (5, 5') for the passage of a fluid from one chamber to the other, and spring means (15) for pushing the piston in a predetermined direction, tending to cause a pressure increase in one of the chambers; the piston is mounted on a rod formed of two aligned rod elements (7, 8), with means (9) for bringing closer and separating their adjacent extremities; it comprises means for providing a controlled fluid leak through the conduits (5, 5') of the piston, said means consisting of a groove (25) provided in the piston (2') or washers (12, 13) which can be deformed due to the existence of an undercut (33) in one of the rod elements. It provides for the automatic return of the seat and/or the back of the seat to a predetermined position when the passanger leaves the seat.
