VICKERS液控伺服閥主要是指電液伺服閥,它在接受電氣模擬信號(hào)后，相應(yīng)輸出調(diào)制的流量和壓力。它既是電液轉(zhuǎn)換元件,，也是功率放大元件,，它能夠?qū)⑿」β实奈⑷蹼姎廨斎胄盘?hào)轉(zhuǎn)換為大功率的液壓能（流量和壓力）輸出。在電液伺服系統(tǒng)中,，它將電氣部分與液壓部分連接起來(lái)，實(shí)現(xiàn)電液信號(hào)的轉(zhuǎn)換與液壓放大,。VICKERS電液伺服閥是威格士電液伺服系統(tǒng)控制的核心。
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(jiàn)圖),。當(dāng)輸入線圈通入電流 VICKERS伺服閥
時(shí)，檔板向右移動(dòng),，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(dòng)。高壓油從S流向C2,，送到負(fù)載。負(fù)載回油通過(guò) C1流過(guò)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(dòng)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,。
