它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(zhǎng)半徑圓弧、兩段短半徑圓弧和四段過(guò)渡曲線八個(gè)部分組成，且定子和轉(zhuǎn)子是同心的。在圖示轉(zhuǎn)子順時(shí)針?lè)较蛐D(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(kāi)。這種泵的轉(zhuǎn)子每轉(zhuǎn)一轉(zhuǎn)，每個(gè)密封工作腔完成吸油和壓油動(dòng)作各兩次，所以稱為雙作用葉片泵。泵的兩個(gè)吸油區(qū)和兩個(gè)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(shí)流量是脈動(dòng)的，當(dāng)葉片數(shù)為4的倍數(shù)時(shí)脈動(dòng)率小。為此，雙作用葉片泵的葉片數(shù)一般都取12或16。
