PARKER派克柱塞泵
柱塞泵柱塞往復運動(dong)總行(xing)程L是(shi)不(bu)變(bian)(bian)(bian)(bian)的(de)(de),由凸輪(lun)的(de)(de)升程決定。柱塞每循環的(de)(de)供(gong)油(you)量(liang)大小(xiao)取決于(yu)供(gong)油(you)行(xing)程,供(gong)油(you)行(xing)程不(bu)受凸輪(lun)軸控(kong)制是(shi)可變(bian)(bian)(bian)(bian)的(de)(de)。供(gong)油(you)開始時刻不(bu)隨供(gong)油(you)行(xing)程的(de)(de)變(bian)(bian)(bian)(bian)化而變(bian)(bian)(bian)(bian)化。轉動(dong)柱塞可改變(bian)(bian)(bian)(bian)供(gong)油(you)終了時刻,從而改變(bian)(bian)(bian)(bian)供(gong)油(you)量(liang)。
