力士樂（rexroth）氣缸--德國原裝
力士樂氣壓傳動中將壓縮氣體的壓力能轉換為機械 能的氣動執行元件。氣缸有做往復直線運動的和做往復擺動兩種類型。
做往復直線運動的氣缸又可分為單作用氣缸、雙作用氣缸、膜片式氣缸和沖擊氣缸4種。
①單作用氣缸：僅一端有活塞桿，從活塞一側供氣聚能產生氣壓，氣壓推動活塞產生推力伸出，靠彈簧或自重返回。
②雙作用氣缸：從活塞兩側交替供氣，在一個或兩個方向輸出力。
③膜片式氣缸：用膜片代替活塞，只在一個方向輸出力，用彈簧復位。它的密封性能好，但行程短。
④沖擊氣缸：這是一種新型元件。它把壓縮氣體的壓力能轉換為活塞高速（10～20米/秒）運動的動能，借以做功。
⑤無桿氣缸：沒有活塞桿的氣缸的總稱。有磁性氣缸，纜索氣缸兩大類。
做往復擺動的氣缸稱擺動氣缸，由葉片將內腔分隔為二，向兩腔交替供氣，輸出軸做擺動運動，擺動角小于 280°。此外，還有回轉氣缸、氣液阻尼缸和步進氣缸等。
