Abstract
A simply constituted steam engine efficiently obtains mechanical energy not only from a heat source of a high temperature but also from the exhaust heat of an internal combustion engine and various kinds of heat sources of a low-temperature state such as the solar heat. In the engine, a rotor () having a folded jet pipe () is rotatably supported in a sealed container () filled with a liquid. A heating portion () is inserted in a center cylinder () at the center of the rotor, and a fluid of a high temperature is passed therethrough to vaporize the liquid sucked through the suction pipe () of the rotor (). A mixture of steam and liquid is jetted from the jet pipe () due to the pressure of the steam that is vaporized to rotate the rotor (). A check valve () for jetting and a check valve () for suction are disposed at the ends of the jet pipe () and the suction pipe (). The jetted steam is guided to a condenser () disposed on the sealed container (), and is condensed and is refluxed into the sealed container (). A vacuum pump () is connected to the condenser (), and the pressure in the sealed container is held at the saturated steam pressure.
