A system for operating a valve comprising a motor shaft driven by a motor; a first cam with a profile mounted to the motor shaft, a second cam with a profile mounted to the motor shaft; a non- contact sensor proximate to the first cam; and a valve actuator. The valve actuator follows the profile of the second cam. A selected position of the valve actuator may be set by activating the motor to a position determined by sensing the first cam profile by the non-contact sensor.

L'invention porte sur un système pour actionner une soupape, comprenant un arbre moteur entraîné par un moteur ; une première came avec un certain profil, montée sur l'arbre moteur, une seconde came avec un certain profil, montée sur l'arbre moteur ; un capteur sans contact, disposé à proximité de la première came ; et un actionneur de soupape. L'actionneur de soupape suit le profil de la seconde came. Une position sélectionnée de l'actionneur de soupape peut être réglée par activation du moteur jusqu'à une position déterminée par détection du profil de la première came par le capteur sans contact.
