摘要:
The invention concerns a hydraulic steering arrangement (1) with a supply connection arrangement having at least a high-pressure connection (P) and a low-pressure connection (T), a working connection arrangement having at least two working connections (L, R), a steering unit (7), which can be activated by a steering transducer (2), the steering unit having a first load-sensing connection (LS1), and a steering valve (8) having a second load-sensing connection (LS2), the steering unit (7) and the steering valve (8) being arranged in parallel with each other between the supply connection arrangement and the working connection arrangement. It is endeavoured to ensure a good steering behaviour. For this purpose, a priority valve (12) is connected in series with the high-pressure connection (P), said priority valve (12) having a third load-sensing connection (LS3), which is connected with the first load-sensing connection (LS1) via a pipe (23), in which is located a control valve (24) that can be activated by the second load-sensing connection (LS2).
