摘要：A servo-steering mechanism for vehicles with a feedback of a load- dependentreaction moment onto the steering hand wheel by means of at least one reactionpressure cylinder connected with a working pressure chamber, in which a reactionpressure piston operating onto the steering hand wheel is adapted to be actuated in onedirection of its piston axis by the working pressure and in the other direction of its pistonaxis is adapted to be supported at a support spring and is also adapted to come intoabutment at a stop fixed relative to the reaction pressure cylinder, when the workingpressure has been brought to a value corresponding to the prestress of the supportspring; between its starting position with an unstressed support spring and its shut-off orturn-off position at the associated stop the reaction pressure piston thereby comes intoadditional abutment at least at one reducing spring counteracting the working pressure,whereby the reducing spring is adapted to be supported either directly or by way of atleast one further reducing spring at a counter abutment of the reaction pressurecylinder.
