Title (EN) A DEVICE FOR CONTROLLING AT LEAST ONE VALVE IN AN INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF DE COMMANDE D'AU MOINS UNE SOUPAPE DANS UN MOTEUR À COMBUSTION INTERNE
Abstract:
(EN) The invention relates to a gas valve actuation device for an internal combustion engine, wherein the device comprises a first means for actuating two gas valves (5) in a first lift event, a second means for selectively actuating a first one (5) of said two gas valves in a second lift event, a fluid circuit (150) for controlling actuation of said first gas valve (5) in the second lift event, wherein the fluid circuit (150) comprises a first fluid circuit valve (152), which is arranged to be controlled by the first actuation means.
(FR) L'invention concerne un dispositif d'actionnement d'une soupape à gaz pour un moteur à combustion interne, le dispositif comprenant un premier moyen destiné à actionner deux soupapes à gaz (5) dans un premier événement de levage, un second moyen destiné à actionner sélectivement une première soupape (5) parmi le deux soupapes à gaz dans un second événement de levage, un circuit de fluide (150) destiné à commander l'actionnement de la première soupape à gaz (5) dans le second événement de levage, le circuit de fluide (150) comprenant une première soupape de circuit de fluide (152) conçue pour être commandée par le premier moyen d'actionnement.
