REXROTH力士樂PV7葉片泵設第一級泵輸出壓力為p1，第二級泵輸出壓力為p2，則該泵的最終輸出壓力為p1+p2：。但這需要一個基本條件：第一個泵的輸出流量應該正好滿足第二級泵的輸人流量的需要，否則會造成油液的空穴現象，引起噪聲，并降低泵的效率。由于兩個泵的定子內壁曲線和寬度等不可能做得*一樣，兩個單級泵每轉一周的容量就不可能*相等。為了平衡兩個泵的流量與載荷關系，在泵體內設有一個載荷平衡閥，使第一級泵的油液輸出與平衡閥的大端1相通，使第二級泵的輸出油路與平衡閥的小端2相通，這樣，當第一級泵的輸出流量大于第二級泵的輸人流量時，多余的油液經平衡閥的大端頂開平衡閥，并由泄油口流回它的進油口，使兩個泵的流量與載荷獲得平衡；如果第一級泵的輸出流量小于第二級泵的需要時，油壓p1要降低，使平衡閥被推向左側，平衡閥的一級泄油口會關閉，而處于閥右側的平衡油口會打開，第二級泵輸出的部分油液從管路2經該閥口流回第二級泵的進油口而獲得流量的補充和平衡。REXROTH力士樂PV7葉片泵少量現貨圖片展示如下：
