Rexroth比例閥是螺紋將電磁比例插裝件固定油路集成塊上元件，螺旋插裝閥具有應(yīng)用靈活、節(jié)省管路和成本低廉等特點，近年來工程機械上應(yīng)用越來越廣泛。常用螺旋插裝式比例閥有二通、三通、四通和多通等形式，二通式比例閥主比例節(jié)流閥，它常它元件一起構(gòu)成復(fù)合閥，對流量、壓力進行控制；三通式比例閥主比例減壓閥，也是移動式機械液壓系統(tǒng)中應(yīng)用較多比例閥，它主對液動操作多路閥先導(dǎo)油路進行操作。利用三通式比例減壓閥可以代替?zhèn)鹘y(tǒng)手動減壓式先導(dǎo)閥，它比手動先導(dǎo)閥具有更多靈活性和更高控制精度?？梢灾瞥扇鐖D1所示比例伺服控制手動多路閥，不同輸入信號，減壓閥使輸出活塞具有不同壓力或流量進而實現(xiàn)對多路閥閥芯位移進行比例控制。
Rexroth比例閥利用車身與車橋之間的距離變化（外界作用力）來改變彈簧的預(yù)緊力，隨著車輛載荷的增加，相應(yīng)地進行調(diào)整，使得在任何載荷條件下都能得到一個近似理想的制動力分配。它安裝在制動總泵與后輪制動分泵之間的管道上，由殼體、柱塞、閥門、彈簧等組成。殼體進油孔與制動總泵出油孔相通，出油孔與車輪制動分泵相通。當外界作用力小時，感載比例閥的柱塞在彈簧預(yù)緊力的作用下被推至zui右邊，兩孔相通，總泵與分泵壓力相等。當外界作用力大于彈簧預(yù)緊力，迫使柱塞左移，令柱塞與閥門接觸并關(guān)閉了閥門，切斷總泵通向分泵的通道；若外界作用力壓力繼續(xù)增大，又會使柱塞右移，柱塞與閥門脫離接觸，閥門又被打開，總泵與分泵又相通。這樣比例閥反復(fù)動作使分泵的液壓不斷得到調(diào)整，也即不斷調(diào)整了后輪制動力。比例閥來調(diào)節(jié)所需要的流量。這種傳統(tǒng)的氣動控制系統(tǒng)要想要有多個輸出力和多個運動速度，就需要多個減壓閥、節(jié)流閥及換向閥。這樣，不僅元件需要多，成本高，構(gòu)成系統(tǒng)復(fù)雜，且許多元件都需要預(yù)先進行人工調(diào)節(jié)。
