Patent ID: 7913493

Claim:
A steam engine, comprising: a displacement engine having a rotor that rotates; a steam-generating portion arranged under the displacement engine and being communicated with the displacement engine to generate steam by heating a liquid contained therein; and a condenser arranged over the displacement engine and being communicated with the displacement engine to condense the steam of the liquid, wherein the rotor is provided with a plurality of operation chambers, a volumetric capacity of the operation chambers increasing on a side that is moving upward with a rotation of the rotor, and decreasing on a side that is moving downward with the rotation of the rotor, and wherein the steam of the liquid generated in the steam-generating portion is fed into the operation chambers on the side moving upward with the rotation of the rotor, and a liquid condensed by the condenser is fed into the operation chambers on the side moving downward with the rotation of the rotor and is refluxed into the steam-generating portion.
