<p>The invention relates to an electro-mechanical actuator provided with a volatile liquid, under the action of a source of heat and meant to actuate a solar motor with a rolling rotor. According to the invention, the actuator comprises an elastic chamber () manufactured as a silphon which is fixed on a metal support () made of brass, in contact with one of the faces of a battery () of Peltier elements, while the other face of the battery () is in contact with an aluminium radiator () which is under the action of the air stream produced by a fan (), in order to eliminate the influence of the environmental temperature, the elastic chamber () partially filled with a volatile liquid () is protected by a cylindrical thermally insulating jacket () provided on the outside with a reflective metal foil (), said thermally insulating space being closed by a thermally insulating disk () located near the frontal side of the elastic chamber () which makes one piece, at the upper part, with a driving rod () guided by a support () positioned by means of two spacing rods ().</p> |
