Abstract

Système d'actionnement de soupape de moteur pour un moteur à combustion interne comprenant une culasse montée sur un bloc-cylindres afin de former au moins une chambre de combustion, le système d'actionnement de soupape de moteur comprenant une première soupape mobile entre une position ouverte et une position fermée pour ouvrir de manière sélective un premier orifice sur la culasse, une seconde soupape mobile entre une position ouverte et une position fermée pour ouvrir de manière sélective un second orifice sur la culasse, un culbuteur qui se déplace sur la base de la rotation d'une came, et l'une des première et seconde soupapes étant actionnée mécaniquement par le culbuteur et l'autre des première et seconde soupapes étant actionnée par un système d'alimentation en pression hydraulique. Le système d'alimentation en pression hydraulique comprend au moins une pompe conçue pour distribuer un fluide hydraulique à un actionneur hydraulique qui actionne la soupape actionnée hydrauliquement.
