The hydraulic steering device includes: a supply port device having a pressure port and a tank port; the working port device is provided with two working ports; a main flow path having a main orifice and at least one other orifice downstream of the main orifice, the main flow path being arranged between the pressure port and the working port device; a backflow flow path arranged between the working port device and the tank port; a measuring motor; an amplification flow path having an amplification orifice and arranged between the pressure port and the working port device; and an adjustable pressure source connected to the pressure port and having a load sensing port wherein the main discharge orifice is connected between the main flow path downstream of the main orifice and the return flow path. The steering device should have the possibility of dynamic steering with a simple structure. A dynamic main orifice is connected between the load sensing port and the main flow path downstream of the main orifice, and a dynamic discharge orifice is connected between the load sensing port and the return flow path, the dynamic discharge orifice opening when the dynamic main orifice is closed.
液压转向装置包括:具有压力端口和箱端口的供应端口装置;具有两个工作端口的工作端口装置;具有主孔口和在主孔口下游的至少一个其他孔口的主流路,主流路布置在压力端口与工作端口装置之间;布置在工作端口装置与箱端口之间的回流流路;测量马达;具有放大孔口并且布置在压力端口与工作端口装置之间的放大流路;以及连接到压力端口并且具有载荷感应端口的可调节压力源,其中,主排放孔口连接在主孔口下游的主流路与回流流路之间。该转向装置应具有带有简单结构的动态转向的可能性。动态主孔口连接在载荷感应端口与主孔口下游的主流路之间,并且动态排放孔口连接在载荷感应端口与回流流路之间,动态排放孔口在动态主孔口闭合时打开。
