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 (5) having a folded jet pipe (51) is rotatably supported in a sealed container (1) filled with a liquid. A heating portion (9) is inserted in a center cylinder (50) 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 (52) of the rotor (5). A mixture of steam and liquid is jetted from the jet pipe (51) due to the pressure of the steam that is vaporized to rotate the rotor (5). A check valve (53) for jetting and a check valve (54) for suction are disposed at the ends of the jet pipe (51) and the suction pipe (52). The jetted steam is guided to a condenser (2) disposed on the sealed container (1), and is condensed and is refluxed into the sealed container (1). A vacuum pump (23) is connected to the condenser (2), and the pressure in the sealed container is held at the saturated steam pressure.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
