8) 低噪音
9）長(zhǎng)壽命
10）優(yōu)良的功率/重量比
11）模塊化設(shè)計(jì)
力士樂(lè)油泵在路面機(jī)械應(yīng)用中涵蓋了壓路機(jī)，攤鋪機(jī)，路面冷熱器設(shè)備，在路面機(jī)械，

      在驅(qū)動(dòng)軸驅(qū)動(dòng)軸 (1) 的齒上安裝有轉(zhuǎn)子 (2)，它在定子環(huán) (3) 內(nèi)回轉(zhuǎn)。葉片 (4) 安裝在轉(zhuǎn)子槽內(nèi)，轉(zhuǎn)子轉(zhuǎn)動(dòng)時(shí)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 (5) 密封。由于定子環(huán)是雙偏心結(jié)構(gòu)，因此形成對(duì)稱布置的兩個(gè)吸油區(qū)和兩個(gè)壓油區(qū)，因此傳動(dòng)軸的徑向液壓力相互平衡而卸載。軸僅傳遞驅(qū)動(dòng)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 (6)，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 (7)。這樣就能迅速地對(duì)泵進(jìn)行維護(hù)和修理。
     由于 PVQ 泵的設(shè)計(jì)結(jié)構(gòu)，使其特別適用于行走機(jī)械應(yīng)用。由于配油盤的特殊結(jié)構(gòu)，而能夠補(bǔ)償轉(zhuǎn)子體的熱膨脹和能夠?qū)ν蝗坏膲毫ψ兓鸬降挚棺饔谩Ｍㄟ^(guò)將配油盤分成柔性盤(7) 和端蓋 (8) 而形成反向壓力腔 (9)，以平衡在擠壓器中的壓力。這就保證了轉(zhuǎn)子和柔性盤之間的*間隙，因而保證泵擁有的容積效率。
