<p>The air storing hood moves in a liquid containing tank and as the air is evacuated, the hood bears on irregular step spiral guides, to follow the sun's orbit by a transference of vertical movement into circular. A vertically regulated triangular bearing modifies the vertical position of a mobile circular arc that bears on it, during its rotation in the horizontal plane. There is a solar operated thermostatic valve with a cover on its west side and a regulating valve connected to the hood to control the exit flow of air or water.</p> |
