Abstract
A Stirling engine generating system comprises a Stirling engine driven by solar heat which is used as a heat input source for the engine, a generator driven by the Stirling engine, a temperature sensor detecting the temperature of an operational gas enclosed in an operational space of the engine, an operational gas tank communicated with the operational space via a pair of conduits, one way valves interposed in the corresponding conduits so as to invert the flow direction of the operational gas in each conduit, opening and closing valves each of which is interposed in the respective conduit between the one way valve and the operational gas tank, a field magnet control device for adjusting the rotational speed of the generator and a temperature regulation device for controlling the opening and closing action of the opening and closing valves to vary the operational gas pressure in the operational space in response to a detected signal of the temperature sensor and for controlling the field magnet control device.
