style="text-indent:25px">雙作用氣缸體:從活塞兩側(cè)交替供氣，在一個(gè)或兩個(gè)方向輸出力。雙作用氣缸體的活塞前進(jìn)或后退都能輸出力（推力或拉力）。結(jié)構(gòu)簡(jiǎn)單，行程可根據(jù)需要選擇。為了吸收行程終端氣缸體運(yùn)動(dòng)件的撞擊能，在活塞兩端設(shè)有緩沖墊，以保護(hù)氣缸體不受損傷。雙作用氣缸體還可以分為單活塞桿型和雙活塞桿型，雙活塞桿型氣缸體的活塞兩側(cè)受壓面積相等，兩側(cè)運(yùn)動(dòng)行程和輸出力是相等的。雙作用氣缸體常用于長(zhǎng)行程的工作臺(tái)的裝置上。單作用氣缸體:*一端有活塞桿，從活塞一側(cè)供氣聚能產(chǎn)生氣壓，氣壓推動(dòng)活塞產(chǎn)生推力伸出，靠彈簧或自重返回。單作用氣缸體結(jié)構(gòu)簡(jiǎn)單，耗氣量少。缸體內(nèi)安裝了彈簧，縮短了氣缸體的有效行程。彈簧的反作用力隨壓縮行程的增大而增大，故活塞桿的輸出力隨運(yùn)動(dòng)行程的增大而減小。彈簧具有吸收動(dòng)能的能力，可減小行程中斷的撞擊作用。一般用于行程短、對(duì)輸出力和運(yùn)動(dòng)速度要求不高的場(chǎng)合。江陰氣缸生產(chǎn)氣缸體蓋上也鑄有很多散熱片,起散熱作用。</p><div
