Abstract
A Stirling engine includes a heater device for collecting solar radiation energy, a heater tube disposed in the heater device and connecting the expansion space and the compression space of cylinder containing a piston, and a transparent partition located in the heater device for defining a closed space. A heat storage material is positioned in the closed space and a temperature detecting apparatus is provided for detecting the temperature of the heat storage material. A pressure regulating arrangement regulates the pressure of a working gas in a working space located between the expansion space and the compression space of the cylinder. A control device controls the pressure regulating arrangement in response to a signal from the temperature detecting apparatus.
