氣動執行機構俗稱氣動頭又稱氣動執行器，執(zhi)行(xing)(xing)器(qi)按(an)其能(neng)源形式(shi)分為(wei)氣(qi)(qi)(qi)動(dong)，電(dian)動(dong)和液動(dong)三大類，它們各有特(te)點，適用(yong)于不同的(de)場合。氣(qi)(qi)(qi)動(dong)執(zhi)行(xing)(xing)機(ji)構是執(zhi)行(xing)(xing)器(qi)中的(de)一種類別。氣(qi)(qi)(qi)動(dong)執(zhi)行(xing)(xing)器(qi)還可以分為(wei)單作(zuo)(zuo)用(yong)和雙作(zuo)(zuo)用(yong)兩種類型：執(zhi)行(xing)(xing)器(qi)的(de)開(kai)(kai)關(guan)動(dong)作(zuo)(zuo)都通過氣(qi)(qi)(qi)源來驅(qu)動(dong)執(zhi)行(xing🥂)(xing)，叫做(雙作(zuo)(zuo)用(yong))。(單作(zuo)(zuo)用(yong))的(de)開(kai)(kai)關(guan)動(dong)作(zuo)(zuo)只有開(kai)(kai)動(dong)作(zuo)(zuo)是氣(qi)(qi)(qi)源驅(qu)動(dong)，而關(guan)動(dong)作(zuo)(zuo)是彈簧。
