REXROTH力士樂齒輪泵供油(you)(you)(you)(you)過程：當(dang)凸(tu)輪軸轉(zhuan)到凸(tu)輪的凸(tu)起部分(fen)時，凸(tu)輪體被頂(ding)起，柱塞(sai)彈簧被壓(ya)縮，柱塞(sai)受(shou)彈簧的反作用力后向上運動，燃油(you)(you)(you)(you)受(shou)壓(ya)，這時會有一部分(fen)燃油(you)(you)(you)(you)經油(you)(you)(you)(you)孔流(liu)回噴油(you)(you)(you)(you)泵上體油(you)(you)(you)(you)腔(qiang)。

REXROTH力士樂齒輪泵供油過程：當凸輪軸轉到(dao)(dao)凸輪的(de)凸起(qi)(qi)部(bu)分時，凸輪體被(bei)頂起(qi)(qi)，柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)彈簧被(bei)壓(ya)(ya)(ya)縮，柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)受彈簧的(de)反作(zuo)用(yong)(yong)力(li)(li)后(hou)向上運動，燃油(you)(you)(you)(you)(you)(you)受壓(ya)(ya)(ya)，這時會有(you)一(yi)部(bu)分燃油(you)(you)(you)(you)(you)(you)經(jing)油(you)(you)(you)(you)(you)(you)孔流回噴油(you)(you)(you)(you)(you)(you)泵(beng)(beng)上體油(you)(you)(you)(you)(you)(you)腔(qiang)。當柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)頂面遮住套筒上的(de)進油(you)(you)(you)(you)(you)(you)孔上緣時，由于柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)和(he)套筒之(zhi)(zhi)間(jian)的(de)配合間(jian)隙很小(xiao)很小(xiao)，(在0.0015到(dao)(dao)0.0025mm之(zhi)(zhi)間(jian))使柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)頂部(bu)的(de)柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)油(you)(you)(you)(you)(you)(you)室(shi)成為(wei)一(yi)個(ge)密封(feng)的(de)油(you)(you)(you)(you)(you)(you)腔(qiang)，這時柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)在彈簧的(de)作(zuo)用(yong)(yong)力(li)(li)下繼續上升，柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)油(you)(you)(you)(you)(you)(you)室(shi)內的(de)油(you)(you)(you)(you)(you)(you)壓(ya)(ya)(ya)迅速升高(gao)，當柱(zhu)(zhu)(zhu)(zhu)塞(sai)(sai)(sai)泵(beng)(beng)油(you)(you)(you)(you)(you)(you)壓(ya)(ya)(ya)力(li)(li)大(da)于出油(you)(you)(you)(you)(you)(you)閥彈簧力(li)(li)和(he)高(gao)壓(ya)(ya)(ya)油(you)(you)(you)(you)(you)(you)管剩余(yu)壓(ya)(ya)(ya)力(li)(li)時，出油(you)(you)(you)(you)(you)(you)閥被(bei)推開，高(gao)壓(ya)(ya)(ya)油(you)(you)(you)(you)(you)(you)經(jing)過(guo)出油(you)(you)(you)(you)(you)(you)閥進入高(gao)壓(ya)(ya)(ya)油(you)(you)(you)(you)(you)(you)管，然(ran)后(hou)通過(guo)噴油(you)(you)(you)(you)(you)(you)器噴入燃燒室(shi)。供油(you)(you)(you)(you)(you)(you)過(guo)程結束。

回油(you)(you)(you)過程(cheng)：當柱(zhu)(zhu)(zhu)塞(sai)向上(shang)供油(you)(you)(you)上(shang)升到柱(zhu)(zhu)(zhu)塞(sai)的斜槽與套(tao)筒上(shang)的回油(you)(you)(you)孔相通時，柱(zhu)(zhu)(zhu)塞(sai)泵油(you)(you)(you)室低(di)壓(ya)油(you)(you)(you)路(lu)便和(he)柱(zhu)(zhu)(zhu)塞(sai)頭部的中孔和(he)徑向孔及斜槽溝通，油(you)(you)(you)壓(ya)突然下(xia)降，這(zhe)時出油(you)(you)(you)閥在(zai)彈簧力(li)的作用(yong)下(xia)迅(xun)速(su)關閉，回油(you)(you)(you)過程(cheng)結束。然后柱(zhu)(zhu)(zhu)塞(sai)還要上(shang)行(xing)，當凸輪的凸起部分轉過去(qu)以后，在(zai)柱(zhu)(zhu)(zhu)塞(sai)彈簧的作用(yong)力(li)下(xia)柱(zhu)(zhu)(zhu)塞(sai)再次下(xia)行(xing)。這(zhe)時又開始了下(xia)一個(ge)循(xun)環。
