德國Rexroth力士樂葉片泵在驅(qū)動軸驅(qū)動軸的齒上安裝有轉(zhuǎn)子 ，它在定子環(huán)內(nèi)回轉(zhuǎn)。葉片安裝在轉(zhuǎn)子槽內(nèi)，轉(zhuǎn)子轉(zhuǎn)動時靠離心力使葉片壓在定子環(huán)的內(nèi)表面。排油腔的端面由配油盤 密封。由于定子環(huán)是雙偏心結(jié)構(gòu)，因此形成對稱布置的兩個吸油區(qū)和兩個壓油區(qū)，因此傳動軸的徑向液壓力相互平衡而卸載。軸僅傳遞驅(qū)動轉(zhuǎn)矩。在吸油區(qū)，葉片部分地卸荷。這能減少磨損和獲得高效率。取下端蓋，可以更換泵芯 ,由轉(zhuǎn)子、葉片、定子環(huán)和配油盤組成，而不必從鐘形罩上卸下泵體。這樣就能迅速地對泵進行維護和修理。
    由于力士樂PVQ泵的設(shè)計結(jié)構(gòu)，使其特別適用于行走機械應(yīng)用。由于配油盤的特殊結(jié)構(gòu)，而能夠補償轉(zhuǎn)子體的熱膨脹和能夠?qū)ν蝗坏膲毫ψ兓鸬降挚棺饔?。通過將配油盤分成柔性盤和端蓋而形成反向壓力腔，以平衡在擠壓器中的壓力。這就保了轉(zhuǎn)子和柔性盤之間的*間隙，因而保泵擁有的容積效率。
    力士樂定量葉片泵的zui大工作壓力210bar（21MPa）和zui大擠壓容積18-193ml。
    Rexroth單聯(lián)/雙聯(lián)定量葉片泵的特點：定排量；由于液壓卸荷的軸而使軸承擁有長壽命；由于液壓卸荷的葉片而僅有很小的磨損；工作噪音低；由于泵芯的互換性，有利于售后服務(wù)；好的效率；壓油口的位置可以選擇；驅(qū)動轉(zhuǎn)向或右旋或左旋；驅(qū)動軸可選圓柱形或花鍵。
    力士樂雙聯(lián)泵：極緊湊的結(jié)構(gòu)；壓油口的位置可分開選擇
    力士樂雙聯(lián)葉片泵|REXROTH雙聯(lián)葉片泵
    葉片泵轉(zhuǎn)子旋轉(zhuǎn)時，葉片在離心力和壓力油的作用下，尖部緊貼在定子內(nèi)表面上。這樣兩個葉片與轉(zhuǎn)子和定子內(nèi)表面所構(gòu)成的工作容積，先由小到大吸油后再由大到小排油，葉片旋轉(zhuǎn)一周時，完成兩次吸油與排油。

    Rexroth雙聯(lián)葉片泵的作用原理和單作用葉片泵相似，不同之處只在于定子表面是由兩段長半徑圓弧、兩段短半徑圓弧和四段過渡曲線八個部分組成，且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時針方向旋轉(zhuǎn)的情況下，密封工作腔的容積在左上角和右下角處逐漸增大，為吸油區(qū)，在左下角和右上角處逐漸減小，為壓油區(qū)；吸油區(qū)和壓油區(qū)之間有一段封油區(qū)把它們隔開。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn)，每個密封工作腔完成吸油和壓油動作各兩次，所以稱為雙作用葉片泵。泵的兩個吸油區(qū)和兩個壓油區(qū)是徑向?qū)ΨQ的，作用在轉(zhuǎn)子上的液壓力徑向平衡，所以又稱為平衡式葉片泵。
    雙作用葉片泵的瞬時流量是脈動的，當葉片數(shù)為4的倍數(shù)時脈動率小。為此，雙作用葉片泵的葉片數(shù)一般都取12或16。
