ABSTRACT:
The invention concerns a hydraulic steering arrangement with a steering motor, a supply path between a pressure source and the steering motor, in which supply path a throttling device and a measuring motor are located, a return path between the steering motor and a pressure sink, in which return path a return throttle is located, and a bypass path, which connects the supply path and the return path on the pressure source end or the pressure sink end, respectively, and which has a bypass throttle. It is endeavoured to make such steering arrangements suitable for fast motorboats. For this purpose it is ensured that with a load on the steering motor the pressure drop over the bypass throttle is larger than the sum of the pressure drops between a point before the first throttle and a point after the last throttle of the throttling device.
