ABSTRACT:
An arrangement for limiting the steering-power in hydraulic servo-steering systems provided with a valve of the type of a three-way three positions valve for controlling a pressure flow from a pressure source to a working space of a preferably higher effective area of a servo-motor or from the working space to a return flow, in which the working space of a preferably lesser effective area is always connected with the pressure source, and the reaction areas with hydraulic reaction areas serve for signalling back a steering sensation to the steering wheel, which reaction areas are arranged to the various effective areas of the servo-motor, and, in combination with respective lever arms, etc., and/or respective reaction areas define a torque dynamometer, etc.
