?伺服閥放大板的結(jié)構(gòu)和原理如圖所示，無信號電流輸入時，銜鐵和擋板處于中間位置。這時噴嘴4二腔的壓力pa=pb，滑閥7二端壓力相等，滑閥處于零位。輸入電流后，電磁力矩使銜鐵2連同擋板偏轉(zhuǎn)θ角。設(shè)θ為順時針偏轉(zhuǎn)，則由于擋板的偏移使pa＞pb，滑閥向右移動。滑閥的移動，通過反饋彈簧片又帶動擋板和銜鐵反方向旋轉(zhuǎn)（逆時針），二噴嘴壓力差又減小。在銜鐵的原始平衡位置（無信號時的位置）附近，力矩馬達(dá)的電磁力矩、滑閥二端壓差通過彈簧片作用于銜鐵的力矩以及噴嘴壓力作用于擋板的力矩三者取得平衡，銜鐵就不再運(yùn)動。同時作用于滑閥上的油壓力與反饋彈簧變形力相互平衡，滑閥在離開零位一段距離的位置上定位。這種依靠力矩平衡來決定滑閥位置的方式稱為力反饋式。如果忽略噴嘴作用于擋板上的力，則馬達(dá)電磁力矩與滑閥二端不平衡壓力所產(chǎn)生的力矩平衡，彈簧片也只是受到電磁力矩的作用。因此其變形，也就是滑閥離開零位的距離和電磁力矩成正比。同時由于力矩馬達(dá)的電磁力矩和輸入電流成正比，所以滑閥的位移與輸入的電流成正比，也就是通過滑閥的流量與輸入電流成正比，并且電流的極性決定液流的方向。
