德国Rexroth力士乐比例溢流阀主要作用；
德国Rexroth力士乐比例溢流阀工作原理是：比例溢流阀通过弹簧力的大小改变溢流压力大大小变化，比例电磁铁作用在弹簧上的力可以按比例调整，所以就输入信号变化比例溢流阀的压力也会变化
德国Rexroth力士乐定压溢流作用：在定量泵节流调节系统中，定量泵提供的是恒定流量。 当系统压力增大时，会使流量需求减小。此时溢流阀开启，使多余流量 溢回油箱，保证溢流阀进口压力，即泵出口压力恒定（阀口常随压力波 动开启）。
德国Rexroth力士乐比例溢流阀稳压作用：溢流阀串联在回油路上，溢流阀产生背压，运动部件平稳性 增加。
德国Rexroth力士乐系统卸荷作用：在溢流阀的遥控口串接溢小流量的电磁阀，当电磁铁通 电时，溢流阀的遥控口通油箱，此时液压泵卸荷。溢流阀此时作为卸荷 阀使用。

溢流阀是安全阀，装在油泵出油处。当液压系统正常工作时，溢流阀“不动作”；当液压系统液压过载时，溢流阀“动作”，直接将液压油返回油箱，避免液压执行机构（如，油缸）因机械过载受损。溢流阀的工作压力是预先调好的，略高于正常工作压力。
