The invention concerns a hydraulic steering () with a steering motor (), a steering unit () with feedback behavior, a steering member activating the steering unit () and a shock valve arrangement () between the steering motor () and the steering unit (). It is endeavored to enable changes of the feedback behavior in a simple manner. For this purpose it is ensured that a switchable feedback suppression device () is located at the side of the shock valve arrangement () facing away from the steering motor ().

Hydraulic steering

The invention concerns a hydraulic steering () with a steering valve () located between a supply connection arrangement (P, T) and a steering motor (). It is endeavored to improve the safety of such a steering. For this purpose, the steering valve () has a hydraulic drive () with a pilot valve arrangement () supplied by a pressure control valve (), a stop valve () being located between the pressure control valve () and the pilot valve arrangement ().

The invention concerns a fully hydraulic steering with a steering member, a steering unit that can be activated by the steering member, said steering unit comprising a supply connection arrangement (P, T) with a pressure connection (P) and a tank connection (T), and a working connection arrangement (L, R) with two working connections (L, R), and a steering motor, which is connected with the working connection arrangement (L, R). It is endeavored to increase the possibilities of steering. For this purpose, it is ensured that an auxiliary force operated steering valve is arranged in parallel to the steering unit between the supply connection arrangement (P, T) and the working connection arrangement (L, R).
