    摘要: A retroactive device as part of a hydraulic servo-steering system that also includes a hydraulic servo-valve device, the retroactive device comprising an arrangement for hydraulically producing a restoring moment into a central position that produces the restoring moment as a function of the pressure differential between a pressure side and a low-pressure side. The system has at least one valve arrangement that, when pressure is applied in the central position of the servo-valve, is adapted to produce a pressure differential between the external and internal chambers of the valve. The valve arrangement is disposed hydraulically in series with the retroactive device.

    摘要: A reaction arrangement on a hydraulic servo-valve arrangement which is designed in the manner of a rotary-slide arrangement, with a rotary slide and with a control bush coaxially surrounding the rotary slide and rotatable relative to the latter, in particular for power steering systems of motor vehicles. Arranged on a shaft part located on the rotary-slide side are axial V-grooves, into which reaction bodies can be pressed with controllable hydraulic pressure. The reaction bodies are guided radially on a bush portion connected fixedly in terms of rotation to the control bush.

    摘要: A control valves for a servo steering system, having an inlet for supplying a hydraulic liquid at a first pressures and an outlet for discharging the hydraulic liquid into a region having a smaller, second pressure, especially into a pressureless reservoir. The control valve has a guide and a valve slide accommodated in the guide so as to be movable therein along an axis. The valve slide is acted upon on one side by the hydraulic liquid with the first pressure and on the opposite side by a defined supporting force. An opening structure is provided on at least one of the valve slide and guide. A cover corresponding to the opening structure is provided on the other of the guide and valve slide. A movement of the valve slide relative to the guide effects a change of a free passage area of the opening structure that is not closed off by the cover, whereby the hydraulic liquid is able to flow from the inlet, through the free passage area, to the outlet. The opening structure has a defined shape such that the free passage area of the opening structure does not depend linearly on the movement of the valve slide
