    • A power-assisted steering system includes a changeover valve unit comprising an input shaft to be rotated by the driver's steering effort applied thereto, an output shaft operatively connected to a hydraulic power cylinder associated with the steering system, a valve assembly for controlling the supply of fluid under pressure from a hydraulic pump to the power cylinder in response to relative rotation between the input and output shafts; and a hydraulic reaction mechanism for applying a reaction force to the input shaft in accordance with a hydraulic reaction pressure applied thereto. The reaction mechanism includes a reaction fluid chamber to be constantly applied with a predetermined small quantity of fluid under pressure and to be applied with a hydraulic pressure caused by relative rotation between the input and output shafts through a throttle. The system is arranged to increase the hydraulic pressure in the reaction fluid chamber in accordance with an increase of travel speed of the vehicle.
    • 一种动力辅助转向系统,包括转换阀单元,该转换阀单元包括由驾驶员施加到其上的转向力旋转的输入轴,可操作地连接到与转向系统相关联的液压动力缸的输出轴, 响应于输入和输出轴之间的相对旋转,从液压泵到动力缸的压力下的流体; 以及用于根据施加到其上的液压反作用压力向输入轴施加反作用力的液压反作用机构。 反应机构包括反应流体室,以在压力下恒定地施加预定量的流体,并且通过节气门施加由输入轴和输出轴之间的相对旋转引起的液压。 该系统被布置成根据车辆的行进速度的增加来增加反应流体室中的液压。
