Abstract

L'invention concerne un dispositif de commande d'exécution (800) destiné à commander le déplacement d'une soupape (515) d'un moteur à combustion interne, le dispositif de commande d'exécution (800) comprenant : une première partie (810) destinée à venir en prise avec un ensemble culbuteur (310) ; et une seconde partie (820) destinée à venir en prise avec un arbre à cames (111); le dispositif de commande d'exécution (800) peut être agencé entre un état déverrouillé (800-1) et un état verrouillé (800-2) avant que la soupape (515) soit ouverte ; dans l'état déverrouillé (800-1), la seconde partie (820) peut être déplacée vers la première partie (810) par l'arbre à cames (111) sans transmettre une force de levage à la soupape (515) pour retarder ainsi une ouverture de la soupape.
