Abstract

L'invention concerne un actionneur électromagnétique, dans lequel un organe mobile est adapté à coulisser selon une direction de déplacement (X-X') entre deux positions extrêmes sous l'effet d'un champ magnétique (F) contenu dans un châssis ferro-magnétique (2). Ce châssis (2) comporte un noyau central (16) qui est disposé transversalement à ladite direction de déplacement (X-X') et l'organe mobile comporte une tige support d'aimant (8), qui est adaptée à coulisser à travers un canal (18) aménagé dans le noyau, et deux masses aimantées (6, 7) qui sont disposées sur la tige support de part et d'autre du noyau, au niveau d'entrefers ménagés dans des parois transversales du châssis.

The invention relates to an electromagnetic actuator, in which a movable member is adapted to slide in a direction of displacement (X-X ') between two extreme positions under the effect of a magnetic field (F) contained in a ferroelectric frame. magnetic (2). This frame (2) comprises a central core (16) which is arranged transversely to said direction of movement (X-X ') and the movable member comprises a magnet support rod (8), which is adapted to slide through a channel (18) arranged in the core, and two magnetized masses (6, 7) which are arranged on the support rod on either side of the core, at air gaps formed in transverse walls of the frame.
