Abstract

L'invention concerne un dispositif électromagnétique à armature mobile, tel qu'un électro-aimant à noyau plongeur. L'électro-aimant 1 comprend un noyau plongeur 4 qui se termine par une surface conique 6 destinée à coopérer, lorsque la bobine 3 de l'électro-aimant est alimentée, avec un siége 7 de forme conique complémentaire supporté par la culasse de l'électro-aimant. Une bague anti-friction et amagnétique 8 est montée entre la surface conique 6 et le siège 7 pour réduire fortement les forces de rémanence et de friction entre ceux-ci et permettre le retour en position de repos du noyau plongeur 4 sous l'action d'une force de rappel très faible. L'invention s'applique notamment à la commande d'éléments à deux positions stables.
