<p>A directing device for solar-power systems, particularly solar collectors, based on the principle of changes in the volume of the thermally expanded medium in the enclosed space of a pressure controlled system by the action of falling solar radiation, consisting of a fixed stand (6) with ball pivot (5), with a movable support brace (4) fitted on it. On this support brace (4), around the ball pivot (5) and fixed symmetrically opposite one another, there are four enclosed chambers (1) with fixed covers (2), and in each of them there is also one guide chamber (7) of a sliding piston (8), whose inner space above the sliding piston (8) is connected by a connecting hole (15) with the inner space of the enclosed chamber (1). At the end of each sliding piston (8), inside the guide chamber (7) of the given enclosed chamber (1), there is an idle pulley (16), across which there is a cord (9), fixed at one end to the fixed cover (2) of this enclosed chamber (1) and the other end to the fixed stand (6).<IMAGE></p> |
