氣缸動作方式：雙作用式、單作用式/彈簧壓回、單作用式/彈簧壓出氣緩沖氣緩沖裝置是由緩沖套,緩沖封圈和緩沖閥組成.當緩沖套插入緩沖密封件時,正常的排氣通道便會被堵塞,被困的空氣被加壓,而舒緩了活塞的慣性.加壓的空氣只可透過缸蓋上的一個受針閥控制的小孔排放,這就構成了緩沖行程的效果.氣缸的理論出力理論出力=活塞面積×空氣壓力雙動氣缸產生的理論出力:伸出:Fe=Π/4*D2*Pg縮回:Fr=Π/4*（D2-d2）*Pg單動氣缸產生的理論出力:伸出:Fe=Π/4*D2*Pg-FsD=氣缸缸徑Pg=空氣壓力(表壓)d=活塞桿直徑Fs=彈簧出力氣缸的負載率負載率=所需出力/理論出力*100%負載率的選取與負載的運動狀態有關,按一般的選取如:負載的運動狀態負載率靜負載<=70%氣缸速度50至500mm/s<=50%氣缸速度超過500mm/s<=30%浙江歐雷凱氣動有限公司不斷創新及提升，以推出更具性價比的氣動產品。天津氣動控制原件氣動閥門
