ABSTRACT:
The springs associated with the control valves of a servo steering system are prestressed at least in that position of the valves where associated connections are blocked. Further, the springs are arranged supporting themselves in the valve by ends of the springs being arranged facing an activating member common to the valve and permitting the entire spring force to be received by the activating member alone. At least one component of each spring is supported by the valve housing, whereby the bias on the one component increases, based on the activating force limit during a reduction of the activating force, and reaches a maximum when power-flow between the activating member and the associated regulating spring is interrupted.
