氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)依(yi)照原(yuan)理與不同槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)機械設(she)計(ji)方(fang)式(shi)有分為(wei)四種(zhong)(zhong)(zhong)五類：第(di)(di)一種(zhong)(zhong)(zhong)是(shi)依(yi)賴活(huo)塞(sai)原(yuan)理進(jin)行槍(qiang)(qiang)機運(yun)(yun)作(zuo)的(de)(de)方(fang)式(shi)，亦(yi)即透(tou)過導(dao)流使氣(qi)(qi)(qi)體推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)，活(huo)塞(sai)連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機，透(tou)過這一串(chuan)的(de)(de)程(cheng)序完成(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。然而活(huo)塞(sai)的(de)(de)運(yun)(yun)作(zuo)以(yi)行程(cheng)為(wei)主，以(yi)行程(cheng)移動(dong)(dong)(dong)(dong)(dong)(dong)距離(li)的(de)(de)長(chang)短劃分，而非以(yi)活(huo)塞(sai)的(de)(de)重(zhong)量或者(zhe)大小(xiao)劃分。第(di)(di)二(er)種(zhong)(zhong)(zhong)是(shi)利用“收集”子彈的(de)(de)高壓(ya)(ya)氣(qi)(qi)(qi)之后再(zai)導(dao)流進(jin)入汽(qi)缸推動(dong)(dong)(dong)(dong)(dong)(dong)活(huo)塞(sai)或整個槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)到槍(qiang)(qiang)機進(jin)行完成(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。第(di)(di)三種(zhong)(zhong)(zhong)是(shi)利用第(di)(di)二(er)種(zhong)(zhong)(zhong)“收集”氣(qi)(qi)(qi)體的(de)(de)原(yuan)理進(jin)行推動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)管連(lian)動(dong)(dong)(dong)(dong)(dong)(dong)槍(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。后一種(zhong)(zhong)(zhong)是(shi)經由氣(qi)(qi)(qi)導(dao)管導(dao)流氣(qi)(qi)(qi)體向后“吹送”槍(qiang)(qiang)機完成(cheng)槍(qiang)(qiang)枝(zhi)(zhi)的(de)(de)自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)/半自(zi)動(dong)(dong)(dong)(dong)(dong)(dong)運(yun)(yun)作(zuo)。因此我們大約可以(yi)分為(wei)：短行程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Short stroke）。長(chang)行程(cheng)活(huo)塞(sai)傳動(dong)(dong)(dong)(dong)(dong)(dong)式(shi)（Long stroke）。氣(qi)(qi)(qi)井集氣(qi)(qi)(qi)操(cao)(cao)作(zuo)（Gas trap）。槍(qiang)(qiang)口增壓(ya)(ya)器（Muzzle booster）。直噴(pen)式(shi)氣(qi)(qi)(qi)動(dong)(dong)(dong)(dong)(dong)(dong)操(cao)(cao)作(zuo)（Direct impingement；也稱(cheng)為(wei)Direct Gas Action）。
