Abstract
L'invention concerne un système d'actionnement (2) qui comprend un ensemble bloc-culasse (3), une glissière (5) sur laquelle est monté l'ensemble bloc-culasse (3), un guide linéaire sur lequel ladite glissière (5) est conçue pour coulisser linéairement et une came cylindrique (4) conçue pour être actionnée en rotation par un moteur et pour coopérer avec la glissière (5) pour commander le mouvement le long du guide linéaire. La surface externe de la came (4) définit un trajet (42) ayant une première section de stationnement (42a), une seconde section de stationnement (42b), une section intermédiaire avant (42c) et une section intermédiaire arrière (42d) reliant la première section de stationnement (42a) annulaire et la seconde section de stationnement (42b) annulaire. La glissière (5) est déplacée vers l'avant, de la première position de fonctionnement à la seconde position de fonctionnement et, respectivement, vers l'arrière, de la seconde position de fonctionnement à la première position de fonctionnement.
