刻不隨供油行程的變化而變化。轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。柱塞泵工作時(shí)，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復(fù)運(yùn)動(dòng)，從而完成泵油任務(wù)，泵油過(guò)程可分為以下三個(gè)階段。

當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后，在彈簧力的作用下，柱塞向下運(yùn)動(dòng)，柱塞上部空間（稱為泵油室）產(chǎn)生真空度，當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開(kāi)后，充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室，柱塞運(yùn)動(dòng)到下止點(diǎn)，進(jìn)油結(jié)束
