充液阀的充液过程为:当蓄能器的压力低于充液阀设定的下限压力时,作用在上限单向阀阀芯3上的液压力低于先导阀4左端弹簧8的作用力,使下限单向阀6关闭,上限单向阀3打开,蓄能器内的压力油经先导阀芯4、节流通道Ⅱ进入主阀右腔,推动主阀芯9克服左腔压力向左移动,逐渐降低主阀开度,P与O口间的节流作用造成P口压力增高。随后P口与A口间的单向阀打开,经节流口向蓄能器供液。当蓄能器压力达到上限时,作用在先导阀右端单向阀阀芯3的液压力大于左端弹簧压力,下限单向阀6打开,上限单向阀3关闭,主阀右腔经先导阀于T口相通泄压,在左端压力作用下克服右端弹簧压力右移,P口与A口间的单向阀关闭,恢复全流量向下游系统供液,充液过程结束。R900516873 DR10DP2-4X/210YMV
