結構特點 （1）結構簡單， （2）工作要求低， （3）端蓋和齒輪的各個齒間槽組成了許多固定的密封工作腔，只能用作定量泵。。
這種高低壓交替的沖擊壓力嚴重降低流量脈動品質，產生噪音和功率消耗以及周期性的沖擊載荷。對泵的壽命影響很大。為防止壓力沖擊，我們希望柱塞腔在接通高低壓時，腔內壓力能平緩過渡，從而避免壓力沖擊。在泵的結構尺寸確定后，取決于吸排有壓力差的大小。在實際工況條件下，泵排油壓力常隨負載改變而變化。要避免在新工況條件下的壓力沖擊，應改變壓縮角 和 以適應壓力差的變化。簡單的方法是在過渡區(qū)開設減振槽。。

隨著靜壓支承技術的進展，進而發(fā)展了一種靜壓支承配油盤，在配油盤配油窗口的外周（或內周）專門開設了一組靜壓支承，在缸體與配有盤平面之間形成一層穩(wěn)定的油膜。在配油機構運轉的配油面間是要承受很高的壓力和相當高的相對滑動速度。所以，配油部位的直徑就需要盡可能小（配油窗口的中徑可以小于柱塞的分布圓直徑），還要避免金屬直接接觸。這樣一來，配油窗口、內外密封帶的半徑便不可隨意選?。ū苊饨M裝時的不統(tǒng)一）。如果內外密封帶或配油窗口過寬，就會將缸體推開，漏損劇增，甚至不能工作。。
