Abstract
Dispositif de distribution (100) d’un moteur thermique d’un groupe de motorisation comprenant : - un arbre à cames (10) agencé dans une culasse du moteur, ledit arbre étant entouré de cames (23) aptes à appuyer sur des soupapes de révolution et mobiles en coulissement selon leur axe de révolution, caractérisé en ce que le dispositif (100) comprend un arbre primaire (30) et un arbre secondaire (40) coaxiaux formant l’arbre à cames (10), l’arbre primaire (30) étant entrainé en rotation par un ensemble de distribution, en étant connecté en permanence à l’arbre secondaire (40) par un système d’accouplement (60) en rotation apte à autoriser une libération de rotation de l’arbre secondaire (40), lequel arbre secondaire est maintenu fixe en position longitudinale. Figure pour l’abrégé : Fig. 5
