回油進(jìn)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(shí)，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，油壓俄然下降，出油閥在彈簧力的作用下活絡(luò)關(guān)閉，接連供油。此后柱塞還要上行，當(dāng)凸輪的凸起有些轉(zhuǎn)過去后，在彈簧的作用下，柱塞又下行。此刻便開端了下一個(gè)循環(huán)

當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起有些頂起滾輪體時(shí)，柱塞彈簧被緊縮，柱塞向上運(yùn)動，燃油受壓，一有些燃油經(jīng)油孔流回噴油泵上體油腔。當(dāng)柱塞頂面遮住套筒行進(jìn)油孔的上緣時(shí)，因?yàn)橹吞淄驳膮f(xié)作空位很?。?.0015-0.0025mm）使柱塞頂部的泵油室成為一個(gè)密封油腔，柱塞持續(xù)上升，泵油室內(nèi)的油壓活絡(luò)增加，泵油壓力>出油閥彈簧力+高壓油管剩下壓力時(shí)，推開出油閥，高壓柴油經(jīng)出油閥進(jìn)入高壓油管，經(jīng)過噴油器噴入燃燒室。
