THERMO-MAGNETIC ACTUATOR

摘要

The invention relates to a thermo-magnetic actuator used for actuating and controlling some elements used in mechanical and electro-mechanical systems. According to the invention, the actuator comprises two rod-shaped permanent magnets (1 and 2) placed on a ferromagnetic plate (3), each magnet (1 and 2) being provided with a polar piece (4 and 5) at its upper extremity, the two pieces (4 and 5) being joined by means of a gadolinium bar (6) embedded in a metal block (7), whereon there is placed a battery (8) with Peltier elements, provided outside with a radiator (9) for heat dissipation.
