美國穆格MOOG伺服閥原裝*
穆格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,。當(dāng)輸入線圈通入電流 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 C1流過回油口,，進(jìn)入油箱。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,。表中是伺服閥的分類。

穆格MOOG公司是設(shè)計(jì),，制造和精密運(yùn)動(dòng)控制產(chǎn)品和系統(tǒng)集成商,。主要產(chǎn)品MOOG閥，MOOG伺服閥,、MOOG伺服電機(jī),、MOOG控制器、MOOG伺服驅(qū)動(dòng)器,，MOOG電液伺服閥,，MOOG柱塞泵等產(chǎn)品。
MOOG伺服閥先導(dǎo)級(jí)采用了伺服射流管,降低了能耗,提高了閥的堅(jiān)固性,。由于伺服射流管先導(dǎo)級(jí)具有很高的無阻尼自然頻率（500HZ）,因此此種閥的動(dòng)態(tài)響應(yīng)較高,并被廣泛應(yīng)用于塑料機(jī)械,、壓鑄機(jī)、重工業(yè)等,并在實(shí)踐中體現(xiàn)出的性能,。
