Abstract
The invention concerns a hydraulic steering () with a supply connection arrangement (P, T), a steering motor () and a steering unit () between the supply connection arrangement and the steering motor (), the steering unit () having a directional section () and a measuring section (), a steering valve () being arranged in parallel to the steering unit (). With such a steering, it is endeavored to achieve the best possible safety. For this purpose, it is ensured that for each steering direction the directional section () comprises a first outlet (AL, AR), which is connected to the steering motor () by means of a first pipe (), and a second outlet (AL, AR), which is connected to the steering motor () by means of a second pipe (), the first outlet (AL, AR) being, in the neutral position of the directional section (), connected to the measuring section (), and the first pipe () being interruptible by means of a valve arrangement ().
