Abstract
The invention concerns a hydraulic steering (1) comprising a supply connection arrangement, a steering motor (2), a high pressure supply (P), and a steering unit (3) arranged between the supply connection arrangement (S) and the steering motor (2), the supply connection arrangement comprising a steering valve (9), and a valve arrangement (27). The task of the hydraulic steering is to improve the safety and faults detection over the state of the art. For this purpose, the steering valve (9) is only deflectable if the valve arrangement (27) is deflected.
