Daikin油泵柱塞泵V15A2R-95,V15A1R-95

當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾輪體時,

柱塞彈簧被壓縮,柱塞向上運(yùn)動,燃油受壓,

一部分燃油經(jīng)油孔流回噴油泵上體油腔.

當(dāng)柱塞頂面遮住套筒上進(jìn)油孔的上緣時

由于柱塞和套筒的配合間隙很小(-)

使柱塞頂部的泵油室成為一個密封油腔

柱塞繼續(xù)上升,泵油室內(nèi)的油壓迅速升高

泵油壓力>出油閥彈簧力+高壓油管剩余壓力時

推開出油閥,高壓柴油經(jīng)出油閥進(jìn)入高壓油管,

通過噴油器噴入燃燒室.

DAIKIN大金柱塞泵工作回油過程

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).
