力士樂Rexroth二級(jí)伺服閥

        德國Rexroth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)就可通過電信號(hào)直接控制油流。

        力士樂三位四通二級(jí)伺服閥,，力士樂4WS2EM 10...XH型伺服閥屬于兩級(jí)閥,，*級(jí)為噴嘴檔板式，由控制信號(hào)控制其出口壓力,，第二級(jí)為滑閥式,，執(zhí)行控制級(jí)至剎車缸的壓力。當(dāng)無信號(hào)作用時(shí),， 由於壓力噴嘴出口油壓力的作用,，使Rexroth伺服閥擋板靠在回油噴嘴上，此時(shí)壓力口的油壓作用在滑閥閥芯上,，使剎車口同計(jì)量油口直接連通,，剎車口壓力同飛行員控制的計(jì)量油壓相等，當(dāng)機(jī)輪角速度檢測(cè)到滑行速度同基準(zhǔn)滑行速度有偏差時(shí),，力矩馬達(dá)接收到偏差電信號(hào),，此時(shí)力矩馬達(dá)驅(qū)動(dòng)檔板向壓力噴嘴偏轉(zhuǎn)，使作用在閥芯上端油壓下降,，在閥芯下端油壓作用下,，閥芯上移，關(guān)小計(jì)量壓力油口,，這將導(dǎo)致控制口壓力降低,，控制口壓力降低到某一值時(shí)，就有對(duì)應(yīng)的制動(dòng)壓力,。
