美國威格士PVH系列變量柱塞泵*
VICKERS變量柱塞泵，可以串聯(lián)齒輪泵。由齒輪泵與柱塞泵共同構(gòu)成的油源系統(tǒng)，可以控制整體的功率曲線，使得恒功率控制不再局限于對(duì)單個(gè)油泵的控制，而是整個(gè)系統(tǒng)。
VICKERS變量柱塞泵其吸入和排出閥都是單向閥。當(dāng)柱塞外拉時(shí)，工作室內(nèi)壓力降低，出口閥關(guān)閉，低于進(jìn)口壓力時(shí)，進(jìn)口閥打開，液體進(jìn)入；柱塞內(nèi)推時(shí)，工作室壓力升高，進(jìn)口閥關(guān)閉，高于出口壓力時(shí)，出口閥打開，液體排出。 帶滑靴結(jié)構(gòu)的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵，安放在缸體中的柱塞通過滑靴與斜盤相接觸，當(dāng)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)時(shí)，斜盤將柱塞從缸體中拉出或推回，完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機(jī)構(gòu)用來改變斜盤的傾角，通過調(diào)節(jié)斜盤的傾角可改變泵的排量。
進(jìn)口VICKERS變量柱塞泵柱塞往復(fù)運(yùn)動(dòng)總行程L是不變的，由凸輪的升程決定。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。供油開始時(shí)刻不隨供油行程的變化而變化。轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻，從而改變供油量。
