典型的伺服閥由永磁力矩馬達(dá)、噴嘴、檔板、閥芯、閥套和控制腔組成(見圖)。當(dāng)輸入線圈通入電流  VICKERS伺服閥
時(shí)，檔板向右移動，使右邊噴嘴的節(jié)流作用加強(qiáng)，流量減少，右側(cè)背壓上升；同時(shí)使左邊噴嘴節(jié)流作用減小，流量增加，左側(cè)背壓下降。閥芯兩端的作用力失去平衡, 閥芯遂向左移動。高壓油從S流向C2，送到負(fù)載。負(fù)載回油通過 C1流過回油口，進(jìn)入油箱。VICKERS伺服閥 閥芯的位移量與力矩馬達(dá)的輸入電流成正比，作用在閥芯上的液壓力與彈簧力相平衡，因此在平衡狀態(tài)下力矩馬達(dá)的差動電流與閥芯的位移成正比。如果輸入的電流反向，則流量也反向。
