<p>The invention relates to a paraffin actuator based on the dilation thereof under the effect of solar heat. According to the invention, the actuator consists of a special black cylinder () filled with a paraffin amount and placed in the focus of a cylindrical concentrator (), the paraffin placed inside the cylinder () melts under the action of solar heat, the dilation of the melted paraffin causing the displacement of an actuation rod () of the actuator, the linear motion of the actuation rod () being further transmitted by means of a flexible cable () provided with a sleeve () and guided by means of two supports (), to a guiding rod () integral with a gear rack () which, in its turn, acts upon a toothed sector () which is made integral with a panel () of voltaic cells by means of a bolt ().</p> |
