机器起动时，泵的驱动轴开始转动。 通过机具和转向泵 (5) 从液压油箱 (8) 吸取液压油。 在机具油缸或转向油缸没有要求时，液压泵处在低压备用状态。 泵输出正确的油量，以补偿内部的漏损。 压力和流量补偿器阀 (7) 维持 3300 kPa (480 psi) 的边缘压力。 液压泵向组合阀 (4) 输送高压油。 组合阀将油压导入两个转向计量泵 (3) 、右侧阀组 (2) 和左侧阀组 (10) 。
转向计量泵 (3) 、右侧阀组 (2) 和左侧阀组 (10) 各有自己的信号管路通到组合阀 (4) 。 从组合阀，分解信号被导向压力和流量补偿器阀 (7) 。 分解信号引导液压和转向泵，以使泵能满足系统负载。 同时，机具和转向泵能满足流量需求。
