Abstract

PURPOSE: To eliminate the supply of working energy from the external by providing a direct sunlight shield vertically on a heat collecting surface of the heat collector and arranging a pressure vessel on both sides of the shield so that the heat collector is operated in accordance with a difference in the pressure of satuated gas within the pressure vessels.
CONSTITUTION: When the sun is in a position, for example, (a) in the drawing, in the pressure vessel 13 receiving the direct sunlight the temperature rises, whereas in the other pressure vessel 14 shielded from the direct sunlight by the shield 12 the temperature is lower than that in the pressure vessel 13. Accordingly, the pressure of the satuated gas in the pressure vessel 13 is higher than that in the pressure vessel 14, so that in a cylinder 7, the pressure on the piston head side is higher than that on the piston rod 9 side. By this, a piston 8 is pushed outwardly and the heat collector 1 is rotated around a pin 4 through the piston rod 9, so that the heat collecting surface 2 is oriented toward the sun. Accordingly, the sun tracking movement can be obtained without supplying any external energy such as electric power.
