Abstract

L'invention concerne un dispositif de réglage destiné à des organes de réglage comme les soupapes de commutation, les vannes-papillons ou les clapets de commande d'intensité de tourbillon des moteurs à combustion interne de véhicules automobiles. Ce dispositif de réglage comprend un arbre (20) relié à un servomoteur (10). L'arbre (20) est relié à un organe de réglage, comme une soupape de commutation ou équivalent. Deux aimants en broches (24, 26) placés à une position prédéterminée par rapport à l'arbre (20) sont, de préférence, reliés à une couronne partiellement dentée. Lors de la rotation de l'arbre (20), les aimants en broches (24, 26) se déplacent par rapport à un capteur de champ magnétique (22) de préférence fixe. Selon l'invention, le capteur de champ magnétique est un capteur Hall linéaire. Le capteur Hall linéaire permet de déterminer trois positions d'arbre différentes. Il s'agit là des deux positions d'arbre déterminées par les aimants en broches (24, 26) et dans lesquelles les aimants sont placés à l'opposé du capteur Hall, et d'une position dans laquelle le capteur Hall ne peut détecter aucun champ magnétique en raison de la position des aimants en broches (24, 26). Dans cette dernière position, un capteur Hall linéaire a une tension du pont définie.
