摘要： The flow of a hydraulic fluid, which occurs under a sliding movement of a piston in a cylinder, is directly controlled by virtue of an extension-stroke pressure control valve and a compression-stroke pressure control valve. At the same time, the pressure in a back pressure chamber is varied, to thereby adjust the valve opening pressure for a main disk valve. This enables control of a damping force over a wide range. In each of the extension-stroke and compression-stroke pressure control valves, a thrust is generated in a slider due to a difference in pressure-receiving areas between a stepped portion of the slider and a sub disk valve in a valve chamber. The valve opening pressure is controlled, according to the balance between the thrust of the slider and a thrust of a proportional solenoid. By reducing the difference in the pressure-receiving areas in the valve chamber, the load applied to the proportional solenoid can be reduced.

摘要： According to an illustrative example of the present invention an oscillation damper is provided with a bypass interconnecting two fluid chambers. A main valve is provided within this bypass for allowing variation of the damping behavior of the oscillation damper. An electro-magnetic valve is used for controlling the hydraulic pressure acting onto the main valve. The electro-magnetic valve is biased toward an emergency position. The biasing force is obtained by two parallel acting springs. A first one of these springs is relatively weak, so that the valve can be transferred by low electric current in a magnetic coil against the action of the weak spring to a first operational position to be used during a major part of the operational time of the oscillation damper. By considerable increase of the electric current the valve can be further transferred into a further operational position which is desired only in exceptional situations. Therefore, a low electric energy consumption is needed for the control of the electro-magnetic valve. The normal operational condition of the electro-magnetic valve is stabilized by the second, harder spring.

摘要： In the case of a vibration damper with a by-pass (32, 32a) between an annular working chamber and a compensating chamber (28), there is in the by-pass (32, 32a) a shut-off valve assembly (36) with a valve shut-off element (42) and a valve seat (40b). The valve shut-off element (42) is for its part subject to the pressure (p.sub.1) in a first section (32) of the by-pass and on the other to the pressure (p.sub.2) in a control chamber (48). The cross-section of a control chamber outlet (46c) can be controlled by an outlet cross-section dimensioning device (52). The shut-off valve assembly (36) is so constructed that at maximum control chamber outlet cross-section the valve shut-off element (42) begins to be lifted off the valve seat (40b) when the throughflow rate through the control chamber outlet (46c) amounts to at least 0.2 times the total throughflow rate through the shut-off valve assembly (36) which becomes adjusted to a damper velocity of 1 m/sec.

摘要： A piston in cylinder shock absorber having a hollow piston rod attached to the piston and a central pipe extending within the piston rod and piston receiving limited flow upon stroking of the piston. A first damper valve creates a variable flow resistance from a reservoir when the piston moves outwardly and a second damper valve creates a variable flow resistance of flow through the piston when the piston is displaced inwardly. A regulating mechanism controls each damper valve by control over the limited flow through the central pipe including an electrically operated servo valve varying outflow from the central pipe to the reservoir.

摘要： A shock-absorber includes a cylinder and a piston arranged within the cylinder and provided with at least one passageway of variable area for controlling flow of a working fluid from one side of the piston to the other side thereof. A controllable device is incorporated within the piston and continuously controlled by external control signals from a control unit to vary the area of the passageway. The external control signals are supplied by the control unit in response to input signals received from sensors which are associated with the shock-absorber. The input signals are related to the instantaneous parameter information obtained from the piston. The value of the external control signals varies during the stroke of the piston at least in part as a function of the input signals.
