力士樂Rexroth二級伺服閥

        德國Rexroth伺服閥結構比較復雜，造價高，對油的質量和清潔度要求高。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，使結構大為簡化。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。利用這一性質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，執行控制級至剎車缸的壓力。當無信號作用時， 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，當機輪角速度檢測到滑行速度同基準滑行速度有偏差時，力矩馬達接收到偏差電信號，此時力矩馬達驅動檔板向壓力噴嘴偏轉，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，關小計量壓力油口，這將導致控制口壓力降低，控制口壓力降低到某一值時，就有對應的制動壓力。
