REXROTH伺服閥0811405547 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。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

 

伺服閥主要用在電氣液壓伺服系統(tǒng)中作為執(zhí)行元件（見液壓伺服系統(tǒng)）。在伺服系統(tǒng)中，液壓執(zhí)行機(jī)構(gòu)同電氣及氣動(dòng)執(zhí)行機(jī)構(gòu)相比，具有快速性好、單位重量輸出功率大、傳動(dòng)平穩(wěn)、抗干擾能力強(qiáng)等特點(diǎn)。另一方面，在伺服系統(tǒng)中傳遞信號(hào)和校正特性時(shí)多用電氣元件。因此，現(xiàn)代高性能的伺服系統(tǒng)也都采用電液方式，伺服閥就是這種系統(tǒng)的必需元件。

 

伺服閥結(jié)構(gòu)比較復(fù)雜，造價(jià)高，對(duì)油的質(zhì)量和清潔度要求高。新型的伺服閥正試圖克服這些缺點(diǎn)，例如利用電致伸縮元件的伺服閥，使結(jié)構(gòu)大為簡(jiǎn)化。另一個(gè)方向是研制特殊的工作油（如電氣粘性油）。這種工作油能在電磁的作用下改變粘性系數(shù)。利用這一性質(zhì)就可通過(guò)電信號(hào)直接控制油流。
