Abstract

L'invention concerne un ensemble de train de soupapes qui est configuré pour effectuer de manière sélective une opération de frein de purge et qui comprend un culbuteur configuré pour tourner autour d'un arbre de culbuteur, un arbre à cames ayant un lobe configuré pour imprimer un mouvement au bras de culbuteur par l'intermédiaire d'une tige de poussée, et un ensemble crosse de soupape fonctionnellement associé au culbuteur et conçu pour être sélectivement mis en prise par le culbuteur afin d'ouvrir au moins l'une d'une première et d'une seconde soupape de moteur. Une capsule de frein de moteur est associée de manière fonctionnelle à l'ensemble crosse de soupape et configurée pour fonctionner dans un mode d'entraînement dans lequel la capsule de frein de moteur n'amène pas l'ensemble crosse de soupape à ouvrir les première ou seconde soupapes de moteur, et un mode de freinage dans lequel la capsule de frein de moteur vient en prise avec l'ensemble crosse de soupape pour ouvrir partiellement la première soupape de moteur pour effectuer l'opération de freinage de purge.
