故同樣平凡稱為容積式液壓泵，圖2-l所示的是一單柱塞液壓泵的工作事理圖.圖中柱塞2裝在缸體3中組成一個(gè)密封容積a，柱塞在彈簧4的浸染下不停壓緊在偏心輪1上。原動(dòng)機(jī)驅(qū)動(dòng)偏心輪1旋轉(zhuǎn)使柱塞2作往來(lái)來(lái)往運(yùn)動(dòng)，使密封容積a的大小發(fā)生周期性的瓜代變革。當(dāng)a由小變大時(shí)就組成部分真空，使油箱中油液在大氣壓浸染下，經(jīng)吸油管頂開(kāi)單向閥6進(jìn)入油腔a而實(shí)現(xiàn)吸油；反之，當(dāng)a由大變小時(shí)，a腔中吸滿的油液將頂開(kāi)單向閥5流入系統(tǒng)而實(shí)現(xiàn)壓油。這樣液壓泵就將原動(dòng)機(jī)輸出的機(jī)械能轉(zhuǎn)換成液體的壓力能，原動(dòng)機(jī)驅(qū)動(dòng)偏心輪賡續(xù)旋轉(zhuǎn)，液壓泵就賡續(xù)地吸油和壓油。
