    • A power steering system which includes a fluid source that supplies pressure fluid of a constant flow rate, a fluid motor for supplementing manual steering torque, a servo-valve for distributing fluid to the fluid motor, and a reaction device for applying hydraulic reaction or feeling to a steering wheel. A magnetic pressure control valve is connected to the reaction device to control fluid pressure applied thereto in accordance with a vehicle operating condition, such a vehicle speed. A flow dividing valve serves to divide the pressure fluid of a constant flow rate in a predetermined ratio into first and second flows which are respectively directed to the servo-valve and reaction device. The predetermined ratio is varied such that the flow rate of the fluid supplied to the reaction device increases as the pressure of the fluid supplied to the fluid motor increases.
    • 一种动力转向系统,包括供给恒定流量的压力流体的流体源,用于补充手动转向扭矩的流体马达,用于向流体马达分配流体的伺服阀,以及用于施加液压反应或感觉的反作用装置 到方向盘。 磁性压力控制阀连接到反应装置,以根据车辆操作条件(如这种车速)来控制施加到其上的流体压力。 分流阀用于将预定比例的恒定流量的压力流体分成分别指向伺服阀和反应装置的第一和第二流。 改变预定比例,使得供应到反应装置的流体的流量随着供应到流体马达的流体的压力增加而增加。
