A hydraulic system for a work vehicle, the hydraulic system comprising: a hydraulically actuated device; a hydraulic pump assembly for supplying a variable output of hydraulic fluid to the hydraulically actuated device; and a proportional control valve, wherein the hydraulic system is arranged such that hydraulic fluid exiting the hydraulically actuated device flows through a restriction of the proportional control valve; and wherein the hydraulic system is configured to control the flow of hydraulic fluid supplied to the hydraulically actuated device by varying the output of hydraulic fluid from the hydraulic pump assembly, and controlling the flow of hydraulic fluid exiting the hydraulically actuated device by adjusting a confinement region of the proportional control valve.

    一种用于作业车辆的液压系统,所述液压系统包括:由液压致动的装置;液压泵组件,用于将液压流体的可变输出供给到所述由液压致动的装置;以及比例控制阀,其中所述液压系统被布置为使得离开所述由液压致动的装置的液压流体流过所述比例控制阀的限制部;并且其中所述液压系统被配置用以通过改变来自所述液压泵组件的液压流体的输出来控制供给到所述由液压致动的装置的液压流体的流量,以及通过调整所述比例控制阀的限制区域来控制离开所述由液压致动的装置的液压流体的流量。
