Abstract

L'invention concerne un détecteur de position pour deux éléments mobiles l'un par rapport à l'autre, dont l'un est relié à au moins un élément disposé à proximité de la bobine de manière à influencer le champ magnétique de la bobine en fonction de la position de l'élément. Un tel détecteur de position peut être construit de manière très compacte et peut être intégré dans le cylindre de commande ou peut coopérer avec celui-ci. Si l'on prévoit l'existence d'au moins deux bobines, l'une peut agir en tant que bobine primaire ou d'excitation et l'autre peut servir de bobine secondaire ou de détection, les deux bobines étant reliées magnétiquement au moins en partie par ledit élément, et l'élément étant de nature à présenter une perméabilité et/ou une conductibilité électrique progressive dans sa direction de mouvement.
