VICKERS美國(guó)威格士伺服閥原裝*，威格士伺服閥原理是：
美國(guó)威格士vickers伺服閥是將電量轉(zhuǎn)變成液壓輸出量的電液轉(zhuǎn)換元件，出現(xiàn)於1940年。到50年代，這種元件的結(jié)構(gòu)趨於成熟。隨著電子技術(shù)和計(jì)算機(jī)技術(shù)的發(fā)展，電液伺服系統(tǒng)的性能得到顯著改善，大大優(yōu)於其他的液壓伺服系統(tǒng)，因而得到廣泛應(yīng)用。電液伺服閥的內(nèi)部結(jié)構(gòu)可分滑閥位置反饋、載荷壓力反饋和載荷流量反饋；閥的級(jí)數(shù)可分單級(jí)、雙級(jí)和多級(jí)。在電液伺服閥中，將電信號(hào)轉(zhuǎn)變?yōu)樾D(zhuǎn)或直線運(yùn)動(dòng)的部件稱(chēng)為力矩馬達(dá)或力馬達(dá)。力矩馬達(dá)浸泡在油液中的稱(chēng)為濕式，不浸泡在油液中的稱(chēng)為乾式。其中以滑閥位置反饋、兩級(jí)乾式電液伺服閥應(yīng)用zui廣。電液伺服閥的工作原理是力矩馬達(dá)在線圈中通入電流后產(chǎn)生扭矩，使彈簧管上的擋板在兩噴嘴間移動(dòng)，移動(dòng)的距離和方向隨電流的大小和方向而變化。例如擋板向右移近噴嘴時(shí)，就在主閥芯兩端面上產(chǎn)生壓力差推動(dòng)主閥芯左移，使壓力油口P S與載荷1口相通，回油口與載荷 2口相通。主閥芯左移的同時(shí)通過(guò)反饋桿對(duì)力矩馬達(dá)產(chǎn)生的力矩和擋板的位移進(jìn)行負(fù)反饋。因此，主閥芯的位移量就能精確地隨著電流的大小和方向而變化，從而控制通向液壓執(zhí)行元件的流量和壓力。
