【簡(jiǎn)單介紹】

威格士vickers當(dāng)凸輪軸轉(zhuǎn)到凸輪的凸起部分頂起滾輪體時(shí)，柱塞彈簧被壓縮，柱塞向上運(yùn)動(dòng)，燃油受壓，一部分燃油經(jīng)油孔流回噴油泵上體油腔。當(dāng)柱塞頂面遮住套筒上進(jìn)油孔的上緣時(shí)，由于柱塞和套筒的配合間隙很小(0.0015-0.0025mm)使柱塞頂部的泵油室成為一個(gè)密封油腔，柱塞繼續(xù)上升，泵油室內(nèi)的油壓迅速升高，泵油壓力>出油閥彈簧力+高壓油管剩余壓力時(shí)，推開(kāi)出油閥，高壓柴油經(jīng)出油閥進(jìn)入高壓油管，通過(guò)噴

【詳細(xì)說(shuō)明】

威格士vickers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)。結(jié)論：通過(guò)上述討論，得出下列結(jié)論

① 威格士vickers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。

② 威格士vickers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。

③ 供油開(kāi)始時(shí)刻不隨供油行程的變化而變化。

④ 轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。
