柱塞泵柱塞往復(fù)運(yùn)動(dòng)總行程L是不變的，由凸輪的升程決定。柱塞每循環(huán)的供油量大小取決于供油行程,供油行程不受凸輪軸控制是可變的。供油開(kāi)始時(shí)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)程可分為以下兩個(gè)階段。

進(jìn)油過(guò)程

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(chēng)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

回油過(guò)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(guò)去后，在彈簧的作用下，柱塞又下行。此時(shí)便開(kāi)始了下一個(gè)循環(huán)。

柱塞泵以一個(gè)柱塞為原理介紹，一個(gè)柱塞泵上有兩個(gè)單向閥，并且方向相反，柱塞向一個(gè)方向運(yùn)動(dòng)時(shí)缸內(nèi)出現(xiàn)負(fù)壓，這時(shí)一個(gè)單向閥打開(kāi)液體被吸入缸內(nèi)，柱塞向另一個(gè)方向運(yùn)動(dòng)時(shí)，將液體壓縮后另一個(gè)單向閥被打開(kāi)，被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油。

一般粒徑在10μm以下的污染物對(duì)泵的影響不太明顯，而大于10μm、特別是在40μm以上時(shí)對(duì)泵的使用壽命就有明顯影響。液壓油中固體污染顆粒極易使泵內(nèi)相對(duì)運(yùn)動(dòng)零件表面磨損加劇，為此需要安裝濾油器降低油的污染程度。過(guò)濾精度要求：軸向柱塞泵10～15μm，葉片泵為25μm，齒輪泵為40μm。泵的污染磨損可以控制在允許范圍之內(nèi)。高精度濾油器使用日益廣泛，可大大延長(zhǎng)液壓泵的使用壽命。
