YUKEN油研創立于1956年總部(bu)位于日本(ben)神(shen)奈川縣，日本(ben)液壓設備的生產(chan)廠家，其產(chan)品(pin)包(bao)括YUKEN油泵、YUKEN柱塞(sai)泵、YUKEN葉片泵、油(you)(you)研雙聯泵、油(you)(you)研液(ye)壓(ya)(ya)泵、油(you)(you)研液(ye)壓(ya)(ya)閥(fa)、油(you)(you)研電磁閥(fa)、油(you)(you)研伺服閥(fa)、油(you)(you)研液(ye)壓(ya)(ya)系統、油(you)(you)研液(ye)壓(ya)(ya)元件和液(ye)壓(ya)(ya)設備(bei)等，產品主要使(shi)用于(yu)加工(gong)中(zhong)心(xin)、液(ye)壓(ya)(ya)電梯、數控機床、自動精密機床以(yi)及進口的關鍵設備(bei)。

柱(zhu)(zhu)(zhu)塞(sai)泵是通過柱(zhu)(zhu)(zhu)塞(sai)桿在(zai)氣缸內(nei)做往復(fu)運(yun)動，從而產生壓力差來輸入流體的。柱(zhu)(zhu)(zhu)塞(sai)泵柱(zhu)(zhu)(zhu)塞(sai)往復(fu)運(yun)動總行程L是不變(bian)的，由凸輪的升(sheng)程決定。柱塞每循(xun)環的供(gong)油量大小取決于供(gong)油行(xing)程,供(gong)油(you)(you)行程(cheng)不(bu)受凸輪(lun)軸控制(zhi)是(shi)可變(bian)的(de)。供(gong)油(you)(you)開始時刻不(bu)隨(sui)供(gong)油(you)(you)行程(cheng)的(de)變(bian)化而變(bian)化。轉動(dong)柱塞(sai)可改(gai)(gai)變(bian)供(gong)油(you)(you)終了時刻，從而改(gai)(gai)變(bian)供(gong)油(you)(you)量。柱塞(sai)泵(beng)(beng)工作時，在噴油(you)(you)泵(beng)(beng)凸輪(lun)軸上的(de)凸輪(lun)與柱塞(sai)彈簧的(de)作用下，迫使柱塞(sai)作上、下往復運動(dong)，從而完成(cheng)泵(beng)(beng)油(you)(you)任務，泵(beng)(beng)油(you)(you)過(guo)(guo)程(cheng)可分為進油(you)(you)過(guo)(guo)程(cheng)和回油(you)(you)過(guo)(guo)程(cheng)兩個階段(duan)

 有(you)人說這(zhe)是(shi)(shi)液(ye)壓(ya)(ya)馬達(da)，有(you)人指出這(zhe)是(shi)(shi)柱塞(sai)泵。之所以(yi)出現混淆(xiao)，主要是(shi)(shi)軸(zhou)向柱塞(sai)馬達(da)的(de)(de)結構形式基本上(shang)與(yu)軸(zhou)向柱塞(sai)泵一樣。從(cong)原理上(shang)講，液(ye)壓(ya)(ya)馬達(da)和液(ye)壓(ya)(ya)泵是(shi)(shi)可逆的(de)(de)，如果用電(dian)(dian)動(dong)機(ji)帶(dai)動(dong)時，輸(shu)出的(de)(de)是(shi)(shi)壓(ya)(ya)力(li)(li)能（壓(ya)(ya)力(li)(li)和流量(liang)）這(zhe)就是(shi)(shi)液(ye)壓(ya)(ya)泵；若輸(shu)入壓(ya)(ya)力(li)(li)油，輸(shu)出的(de)(de)是(shi)(shi)機(ji)械能（轉矩和轉速），則變成了液(ye)壓(ya)(ya)馬達(da)。這(zhe)就好比發電(dian)(dian)機(ji)和電(dian)(dian)動(dong)機(ji)的(de)(de)關(guan)系。
