威格(ge)士(shi)PVH柱塞(sai)泵柱塞往復運動總(zong)行(xing)程(cheng)L是不(bu)變的，由(you)凸(tu)輪的升程(cheng)決定(ding)。柱塞(sai)每(mei)循(xun)環的供油(you)量大小(xiao)取決(jue)於供油(you)行程(cheng),供油(you)行程(cheng)不(bu)受凸(tu)輪軸控(kong)制(zhi)是可變的。供油(you)開(kai)始(shi)時(shi)刻(ke)不(bu)隨供油(you)行程(cheng)的變化(hua)而變化(hua)。轉(zhuan)動柱塞可改(gai)變供油(you)終(zhong)了時(shi)刻(ke)，從而改(gai)變供油(you)量。柱(zhu)塞泵(beng)工(gong)作時(shi)，在(zai)噴油(you)泵凸(tu)輪軸上(shang)的凸(tu)輪(lun)與(yu)柱塞(sai)彈(dan)簧的作用(yong)下(xia)，迫使柱塞(sai)作上(shang)、下往復運動，從而完成泵(beng)油(you)任(ren)務(wu)，泵(beng)油(you)過程(cheng)可分為(wei)以(yi)下三個(ge)階(jie)段。

進油(you)過程(cheng)

當凸(tu)輪的凸(tu)起(qi)部(bu)分轉(zhuan)過去(qu)後(hou)，在(zai)彈(dan)簧力(li)的作用(yong)下(xia)，柱塞向下(xia)運動，柱(zhu)塞(sai)上(shang)部(bu)空間(稱(cheng)為泵(beng)油(you)室)產(chan)生真(zhen)空度，當柱塞(sai)上(shang)端面(mian)把(ba)柱(zhu)塞套(tao)上(shang)的進(jin)油(you)孔(kong)打(da)開(kai)後(hou)，充(chong)滿在油(you)泵上(shang)體油(you)道內(nei)的柴(chai)油(you)經(jing)油(you)孔(kong)進入(ru)泵油(you)室，柱(zhu)塞運動到(dao)下止點(dian)，進(jin)油(you)結(jie)束(shu)。

供油(you)過程(cheng)

當凸(tu)輪軸轉(zhuan)到(dao)凸輪的凸(tu)起(qi)部(bu)分頂起(qi)滾輪體(ti)時(shi)，柱塞(sai)彈(dan)簧被壓(ya)縮，柱塞(sai)向上(shang)運動，燃(ran)油(you)受壓(ya)，壹部(bu)分燃(ran)油(you)經(jing)油(you)孔(kong)流(liu)回噴油(you)泵上(shang)體油(you)腔。當柱塞頂面(mian)遮住(zhu)套(tao)筒(tong)上(shang)進油(you)孔(kong)的上(shang)緣(yuan)時，由(you)於(yu)柱(zhu)塞和套(tao)筒(tong)的配(pei)合間隙(xi)很小(0.0015-0.0025mm)使柱塞(sai)頂部(bu)的泵(beng)油(you)室成(cheng)為壹(yi)個(ge)密(mi)封油(you)腔，柱塞繼(ji)續上(shang)升，泵(beng)油(you)室內(nei)的油(you)壓(ya)迅速(su)升高，泵(beng)油(you)壓(ya)力>出油(you)閥(fa)彈(dan)簧力(li)+高壓(ya)油(you)管(guan)剩余壓(ya)力時(shi)，推(tui)開(kai)出油(you)閥(fa)，高壓(ya)柴(chai)油(you)經(jing)出油(you)閥(fa)進(jin)入(ru)高壓(ya)油(you)管(guan)，通(tong)過噴油(you)器(qi)噴入燃(ran)燒(shao)室(shi)。

回油(you)過程(cheng)

柱塞(sai)向上(shang)供油(you)，當上(shang)行到(dao)柱塞上(shang)的斜(xie)槽(停供邊(bian))與(yu)套筒(tong)上(shang)的回(hui)油(you)孔(kong)相(xiang)通(tong)時(shi)，泵油(you)室低(di)壓(ya)油(you)路便與(yu)柱塞(sai)頭(tou)部(bu)的中孔(kong)和徑(jing)向(xiang)孔(kong)及斜(xie)槽溝通(tong)，油(you)壓(ya)驟然下(xia)降(jiang)，出油(you)閥(fa)在(zai)彈(dan)簧力(li)的作用(yong)下(xia)迅速關閉，停止(zhi)供油(you)。此後(hou)柱(zhu)塞(sai)還(hai)要(yao)上(shang)行，當(dang)凸(tu)輪(lun)的凸(tu)起(qi)部(bu)分轉(zhuan)過去(qu)後(hou)，在(zai)彈(dan)簧的作用(yong)下(xia)，柱塞又(you)下(xia)行(xing)。此(ci)時(shi)便開(kai)始(shi)了下(xia)壹(yi)個(ge)循(xun)環。
