Description
本発明の課題は、高温の熱源に限らず、内燃機関の排熱等低温状態の各種の熱源から機械的エネルギを得ることが可能な熱機関を提供し、しかも、従来の熱機関における上述の問題点を解決することにある。
「ケーシングとその内部で回転するロータとを備えた容積型機関を設置して、その容積型機関の下方には、封入された液体を加熱して蒸気を発生する蒸気発生部を前記容積型機関と連通させて配置するとともに、前記容積型機関の上方には、蒸気を凝縮するコンデンサを前記容積型機関と連通させて配置した蒸気エンジンにおいて、
前記容積型機関は、2個の前記ロータが噛合いながら回転するギヤ型機械であって、前記ロータの各々には、前記ケーシングと接触し径方向に延びる複数の歯部が設けられるとともに、前記歯部と前記ケーシングとにより複数の作動室が形成されており、
前記ロータの回転に伴い上方に移動する側の前記作動室には、前記蒸気発生部で発生させた蒸気が送り込まれ、さらに、前記ロータの回転に伴い下方に移動する側の前記作動室には、前記コンデンサにより凝縮された液体が送り込まれて前記蒸気発生部に還流され、かつ、封入された液体の液位が、蒸気エンジンが作動していない状態では、前記コンデンサ内に設定されている」
ことを特徴とする蒸気エンジンとなっている。
請求項2の発明のように、コンデンサに真空ポンプを接続してコンデンサ内から空気等のガスを排気し、コンデンサ内の圧力を封入された液体の飽和蒸気圧としたときは、発生した蒸気を十分に膨張させエンジン出力を増加させることができると同時に、コンデンサ側の圧力低下に対応して、蒸気発生部の圧力を低下させることができる。その結果、加熱部の温度がそれほど高温ではない場合でも、液体は容易に蒸気となり、エンジンを効率的に作動させ回転エネルギを取り出すことが可能である。
水が封入された蒸気エンジンの蒸気発生部2の下面は、内燃機関の排熱あるいは太陽熱等の熱源によって加熱され、蒸気発生部2内の水は沸騰して比容積が非常に増大し、高圧の蒸気となる。この高圧蒸気は、蒸気発生部2の上方に設けられた短管から、破線の矢印のように容積型機関1に送り込まれる。
本発明のギヤ型機械は、ギヤポンプと同様に、互いに噛合いながら回転する2個のギヤ101と、これらのギヤ101を収容するケーシング102とを有している。ケーシング102の下方の蒸気発生部で発生した蒸気は、ギヤ101の下側に充満し、ギヤ101の回転に応じてギヤ101の隣り合う歯部とケーシング102により囲まれる作動室105内に入る。ギヤ101の外方側に形成される作動室105は、ギヤ101の回転に伴って上方に移動して、最上部付近では低圧のコンデンサ側に開放される。ギヤ101は、蒸気発生部で発生した高圧蒸気とコンデンサ側の低圧蒸気との差圧に基づくトルクによって回転する。
