伺服進口比例閥D91FHE52H5NB00

 D91FHE52H5NB00  R900705259 DBET-5X/200G24K4V-22蓄能器充液狀態變為零壓循環狀態如圖2所示。在充液過程中，泵出油液P經單向閥進人蓄能器回路S ，同時壓力油通過先導閥的先導管作用在壓力補償器的背面該補償器節制泵的流量。隨著油液的不斷充人，直到蓄能器中的壓力克服先導閥的彈簧設定壓力， 先導閥閥芯切換+壓力補償器背面的控制壓力與回油口T相通，此時壓力補償器的閥芯切換，使P與N連通，單向閥關閉。這時，充液過程結束而泵的油液以*小的壓降通過充液閥。 D31VW007C5NYWF

(2)泵由零壓循環狀態轉為蓄能器充液狀態 當蓄能器壓力降至下限時，先導控制閥在彈簧力作用下切換，P經先導閥與壓力補償器的負載信號腔連通，由于彈簧的共同作用，壓力補償器換向，切斷P與N回路+泵的油液再次經單向閥進人蓄能器回路S ，蓄能器充油，直至上一工作循環 。
