　　薄膜的中間部分有金屬片夾著，是硬邦邦不能彎曲的“硬芯”，但周圍的薄膜十分柔軟，使硬芯可以在盒子里左右運(yùn)動(dòng)。薄膜把盒內(nèi)空間一分為二，各形成兩個(gè)“氣室”，即圖中的Ⅰ、Ⅱ、Ⅲ、Ⅳ。每個(gè)氣室都有通氣口，可經(jīng)過這個(gè)口進(jìn)氣或排氣。當(dāng)左室的口進(jìn)氣，右室的口排氣時(shí)，燃?xì)獾膲毫ψ饔迷诒∧ど?，使硬芯向右運(yùn)動(dòng)。反之，若右邊進(jìn)氣，左邊出氣時(shí)，硬芯就向左運(yùn)動(dòng)。可見，如果把盒子看成汽缸，把薄膜和硬芯看成活塞，這不就和蒸汽機(jī)一樣了嗎?</p><p> 　　在燃?xì)獗砝锸褂昧伺c蒸汽機(jī)相同的技術(shù)，使得薄膜和硬芯運(yùn)動(dòng)到最左邊或最右邊時(shí)，燃?xì)獗砜梢岳^續(xù)運(yùn)動(dòng)。具體說來，用兩套風(fēng)箱和薄膜，它們的硬芯都用桿和同一根豎立著的軸相連，這個(gè)軸上有兩個(gè)曲柄，兩個(gè)曲柄也是相差90度，使得兩個(gè)硬芯的動(dòng)作差半步。其中一個(gè)運(yùn)動(dòng)到頭時(shí)，另一個(gè)恰好在中間，永遠(yuǎn)不會(huì)停下來。　上半部是目光平視時(shí)看到的曲軸和連桿，圖的下半部分是從上往下俯視的樣子。從這里可以看出曲軸OC和OC'恰好相差90度。與前面的圖聯(lián)系起來看，其實(shí)連桿AB及BC和左邊的硬芯相連，連桿A'B'及B'C'和右邊的硬芯相連。從這個(gè)圖中我們還可以清楚看到曲軸的轉(zhuǎn)動(dòng)就帶動(dòng)了滾輪計(jì)數(shù)器，從而把耗費(fèi)的氣量累計(jì)下來。</p>
