力士樂Rexroth二級伺服閥
德國Rexroth伺服閥結(jié)構(gòu)比較復(fù)雜，造價高，對油的質(zhì)量和清潔度要求高。新型的伺服閥正試圖克服這些缺點，例如利用電致伸縮元件的伺服閥，使結(jié)構(gòu)大為簡化。另一個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)就可通過電信號直接控制油流。
力士樂三位四通二級伺服閥，力士樂4WS2EM 10...XH型伺服閥屬于兩級閥，*級為噴嘴檔板式，由控制信號控制其出口壓力，第二級為滑閥式，執(zhí)行控制級至剎車缸的壓力。當(dāng)無信號作用時， 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，此時壓力口的油壓作用在滑閥閥芯上，使剎車口同計量油口直接連通，剎車口壓力同飛行員控制的計量油壓相等，當(dāng)機(jī)輪角速度檢測到滑行速度同基準(zhǔn)滑行速度有偏差時，力矩馬達(dá)接收到偏差電信號，此時力矩馬達(dá)驅(qū)動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，就有對應(yīng)的制動壓力。
