Stirling-Maschine

To generate electric power efficiently with a thermoelectromagnetic generator using the heat regenerator of a Stirling engine. When a high-temperature operating gas and a low-temperature operating gas alternately pass through a heat regenerator of a Stirling engine, the temperature of the heat regenerator increases and decreases periodically. A thermoelectromagnetic generator G integrally associated with the heat regenerator has a yoke making up a closed magnetic circuit passing through the heat regenerator, a permanent magnet for supplying magnetic fluxes to the magnetic circuit, and an induction coil responsive to changes in the magnetic fluxes of the magnetic circuit. The heat regenerator which is made of a ferromagnetic material has a Curie temperature which is present in a range of varying temperatures of the heat regenerator. When the temperature of the heat regenerator periodically changes across the Curie temperature, the magnetic fluxes passing through the induction coil are varied greatly each time the temperature of the heat regenerator passes through the Curie temperature, generating a large electromotive force across the induction coil.
