4、電機啟動，節(jié)流閥剛打開，閥口開度還較小時的狀態(tài)
A：要注意的是，在剛開始很短的一段時間內(nèi)，液壓缸無桿腔內(nèi)的壓力還未能推動活塞桿運動時（V=0），即未有油液流動，此時為靜力平衡狀態(tài)。
液壓缸無桿腔內(nèi)的壓力PL將通過負(fù)載反饋油口（見圖4），等值傳遞到負(fù)載閥滑閥右端的彈簧腔內(nèi)（帕斯卡原理，圖中黃色箭頭表示的是力的傳遞方向，并不代表油液流動方向）。此時負(fù)載閥閥芯兩端受靜壓力作用P=PL，閥芯受到150PSI的彈簧力作用使負(fù)載閥工作在右位。導(dǎo)致主控制活塞缸無桿腔內(nèi)的部分壓力油通過泄油路接通油箱。復(fù)位活塞缸中的偏置彈簧力迫使斜盤順時針旋轉(zhuǎn)，液壓泵開始向系統(tǒng)提供較大的流量。
B：當(dāng)液壓缸無桿腔內(nèi)的油液壓力不斷上升，足以推動活塞桿向左移動時（V>0），液壓泵將以較大的排量向液壓缸供油。
盡管壓力油也會流經(jīng)節(jié)流口a，但由于該節(jié)流口很小，并不會在接通負(fù)載閥滑閥彈簧腔（泄油）的油路上造成可觀的功率損失。
注意到節(jié)流閥上下兩端的壓力表間剛好存在著150PSI的壓力差。液壓油通過節(jié)流閥口后所剩余的壓力（負(fù)載壓力）、負(fù)載閥滑閥左端的壓力（泵出口的壓力）、150PSI的彈簧預(yù)緊力三者之間協(xié)同工作，使節(jié)流閥閥口前后壓力差得以保持。對于不同的閥口開度，液壓泵均可提供與之相適應(yīng)的流量。
注意，作用在負(fù)載閥滑閥左端的178PSI壓力抵抗著作用于右端的28PSI壓力和150PSI彈簧力，28PSI加上150PSI剛好等于178PSI（這不是一個等式，卻是一種作用機理）。
