Stirling engine generating system

Stirling engine generating system comprising;

• a Stirling engine driven by solar heat which is used as a heat input source of the engine;
• a generator driven by the Stirling engine;
• a temperature sensor for detecting the temperature of an operational gas enclosed in an operational space of the engine;
• a pressure sensor for detecting an operational gas pressure in the operational space;
• an operational gas tank in communication with the operational space via a pair of conduits;
• a one way valve interposed in each of the conduits so as to invert the flow direction of the operational gas in each conduit;
• an opening and closing valve interposed in both conduits 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 to vary the field current of the generator when the operational gas pressure in the operational space is at a determined pressure and the operational gas temperature in the operational space exceeds a predetermined optimum temperature.
