Abstract

Un actionneur à ressort magnétique comprend un anneau, un piston disposé mobile à l'intérieur de l'anneau, et un cylindre de support non magnétique. Au moins l'anneau ou le piston est magnétique. Grâce aux forces magnétiques générées au moins par l'anneau ou le piston, le piston est disposé initialement dans une première position par rapport à l'anneau. L'application d'une force extérieure provoque le déplacement du piston dans une deuxième position par rapport à l'anneau. La force magnétique crée une force de retour qui fait en sorte que le piston retourne dans la première position par rapport à l'anneau. En variante, le piston peut être fixé, et l'anneau peut être adapté pour se déplacer par rapport au piston de façon similaire. Un ressort hélicoïdal bimétallique peut être enroulé autour du piston.
