威格士VICKERS變量柱塞泵#VICKERS液壓泵
VICKERS柱塞向上供油，當(dāng)上行到柱塞上的斜槽（停供邊）與套筒上的回油孔相通時，泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通，油壓驟然下降，出油閥在彈簧力的作用下迅速關(guān)閉，停止供油。此后柱塞還要上行，當(dāng)凸輪的凸起部分轉(zhuǎn)過去后，在彈簧的作用下，柱塞又下行。此時便開始了下一個循環(huán)。
KERS柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運動所產(chǎn)生的容積變化來進(jìn)行工作的。由于柱塞和柱塞孔都是圓形零件，加工時可以達(dá)到很高的精度配合，因此容積效率高，運轉(zhuǎn)平穩(wěn)，流量均勻性好，噪聲低，工作壓力高等優(yōu)點，但對液壓油的污染較敏感，結(jié)構(gòu)較復(fù)雜，造價較高。
VICKERS柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件：柱塞（plunger）+柱塞套（barrel）構(gòu)成柱塞偶件（plunger and barrel assembly）（圖5-11）、出油閥（delivery valve）和出油閥座（delivery valve seat）構(gòu)成出油閥偶件（delivery valve assembly
VICKERS柱塞和柱塞套是一對精密偶件，經(jīng)配對研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm
VICKERS柱塞頭部圓柱面上切有斜槽，并通過徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。
VICKERS柱塞頭部斜槽的位置不同，改變供油量的方法也不同。
