Abstract

La présente invention concerne un dispositif de commande de soupapes d'un moteur à combustion interne pour un moteur à combustion interne. Le moteur à combustion interne comprend un ou plusieurs cylindres dotés d'une ou de plusieurs soupapes d'admission, d'une ou de plusieurs soupapes d'échappement d'extraction et d'une ou de plusieurs soupapes d'échappement de balayage. Dans un exemple, le dispositif de commande de soupapes du moteur à combustion interne comprend un premier mécanisme d'actionnement de soupape pour ouvrir et fermer les soupapes d'échappement d'extraction et comprend un second mécanisme d'actionnement de soupape pour ouvrir et fermer les soupapes d'échappement de balayage.
