<p>The invention relates to a solar actuator having a bimetallic blade, intended for the conversion of solar energy into a rotation motion. The claimed actuator whose position depending on the sun position is made stable by means of a knuckle joint (16) mounted on a supporting surface (17) consists of a bimetallic converter (1) made of a bimetallic strip shaped according to a conical helical path, the lateral part of this convertor (1) being exposed to solar radiation reflected by a conical concentrator (2), the upper extremity of the converter (1) being anchored to the upper edge of the concentrator (2) by means of an anchor (3), while the lower extremity is anchored to a hub (4) as an extension of a shaft (5) which is mounted, in its turn, in a rolling friction bearing comprising some ball bearings (6 and 7) placed within a support piece (8) integral with the concentrator (2), in extension of a rigid shaft (5) there being placed a flexible shaft (12) by means of a couple (11).</p> |
