比例閥采用閥芯+閥體結構。伺服閥和伺服比例閥主要應用在閉環控制系統，比例閥的驅動裝置是比例電磁鐵。
伺服閥的驅動裝置是力馬達或力矩馬達.閥體兼作閥套。
驅動裝置不同.所以近些年出現了比例伺服閥。
比例閥一般*高幾十Hz，伺服閥中位沒有死區，伺服閥對液壓油液的要求更高.性能參數不同；否則容易堵塞，
用來控制流量和流向，比例閥要求低一些.比例閥有中位死區；
比例閥和伺服閥的區別主要體現在以下幾點：
逐漸向伺服閥靠近，
比例換向閥屬于比例閥的一種，滯環、中位死區、頻寬、過濾精度等特性不同.閥的額定壓降不同；比例換向閥具有與普通換向閥相似的中位機能，
而比例伺服閥性能介于伺服閥和比例閥之間，因此應用場合不同，伺服閥和伺服比例閥采用閥芯+閥套的結構。中位機能種類不同.其它結構的比例閥主要應用在開環控系統及閉環速度控制系統；因為比例閥的性能越來越好；2伺服閥的頻響（響應頻率）更高。閥芯結構及加工精度不同.伺服閥與比例閥之間的差別并沒有嚴格的規定。
，可以高達200Hz左右，需要精過濾才行，而伺服閥中位機能只有O型（Rexroth產品的E型）。

力士樂柱塞泵根據傾斜元件的不同，有斜盤式和斜軸式兩種。斜盤式是斜盤相對回轉的缸體有一傾斜角度，而引起柱塞在泵缸中往復運動。傳動軸軸線和缸體軸線是一致的。這種結構較簡單，轉速較高
，但工作條件要求高，柱塞端部與斜盤的接觸部往往是薄弱環節。斜軸式的斜盤軸線與傳動軸軸線是一致的。它是由于柱塞缸體相對傳動軸傾斜一角度而使柱塞作往復運動。流量調節依靠擺動柱塞缸體
的角度來實現，故有的又稱擺缸式。它與斜盤式相比，工作可靠，流量大，但結構復雜。
軸向柱塞泵與徑向柱塞泵比較，排出壓力高，它一般可在20～50MPa范圍內工作，效率也高，徑向尺寸小、結構緊湊、體積小、重量輕。但結構較徑向柱塞泵復雜，加工制造要求高，價格較貴。
軸向柱塞泵一般用于機床、冶金、鍛壓、礦山及起重機械的液壓傳動系統中，特別廣泛地應用于大功率的液壓傳動系統中。為了提高效率，在應軸向柱塞泵一般都由缸體、配油盤、柱塞和斜盤等主要零
件組成。缸體內有多個柱塞，柱塞是軸向排列的，即柱塞的中心線平行于傳動軸的軸線，因此稱它為軸向柱塞泵。但它又不同于往復式柱塞泵，因為它的柱塞不僅在泵缸內做往復運動，而且柱塞和泵缸
與斜盤相對有旋轉運動。柱塞以一球形端頭與斜盤接觸。在配油盤上有高低壓月形溝槽，它們彼此由隔墻隔開，*保*一定的密封性，它們分別與泵的進油口和出油口連通。斜盤的軸線與缸體軸線之間有
一傾斜角度。
