A hydraulic steering device (1) comprises a supply port (2), a return port (4), a working port arrangement having two working ports (5, 6), a main flow path (7) between the supply port (2) and one of the working ports (5), and a return path (8) between the other working port (6) and the return port. The main flow path (7) comprises a main orifice (A1), a flow meter (9), a first flow meter orifice (A2) upstream of the flow meter, a second flow meter orifice (A3) downstream of the flow meter, and a first working port orifice (A4). The return path comprises a second working port orifice (A5), the load sensing point (17) is arranged between the main orifice (A1) and the first flow meter orifice (A2), the discharge orifice (Ad) is arranged between the load sensing point (17) and the return port (4), and the priority valve arrangement (10) is arranged between the supply port (2) and the main orifice (A1).

    一种液压转向装置(1)包括供应端口(2)、回流端口(4)、具有两个工作端口(5、6)的工作端口装置、在供应端口(2)和工作端口(5)中的一个工作端口之间的主流动路径(7)以及在另一个工作端口(6)和回流端口之间的回流路径(8)。主流动路径(7)包括主孔口(A1)、流量计(9)、在流量计上游的第一流量计孔口(A2)、在流量计下游的第二流量计孔口(A3),以及第一工作端口孔口(A4)。回流路径包括第二工作端口孔口(A5),负载感测点(17)布置于主孔口(A1)和第一流量计孔口(A2)之间,排放孔口(Ad)布置于负载感测点(17)和回流端口(4)之间,并且优先阀装置(10)布置于供应端口(2)和主孔口(A1)之间。
