Abstract
Titre : Arbre à cames d’un moteur à combustion interne. La présente invention a pour objet un arbre à cames (1) d’un moteur à combustion interne (108), comprenant au moins un tube (2) s’étendant le long d’une direction d’allongement principal (A) de l’arbre à cames (1) et autour duquel est disposé au moins une came (4) comprenant une portion de liaison (10) au tube (2) et au moins une portion de génération d’efforts (12) sur une soupape du moteur à combustion interne (108), la portion de génération d’efforts (12) logeant un dispositif d’augmentation (16) de la circonférence de la came (4), le dispositif d’augmentation (16) de la circonférence de la came (4) comprenant au moins un tiroir (18) susceptible de se déplacer entre deux positions (P1, P2) déterminant la circonférence de la came (4) et un organe de poussée (20) qui fait passer le tiroir (18) d’une position à l’autre. Figure 1.
