Abstract

L'invention concerne un mécanisme de distribution (1) pour un moteur à combustion interne. Dans ce mécanisme de distribution, un arbre à cames (4) agit avec une came de commande (2) sur une soupape (7) par l'intermédiaire d'un poussoir (6) dont la piste de contact (8) côté came peut être modifiée au moyen d'un dispositif de commande (11) pour modifier la période d'ouverture d'une soupape. L'invention vise à créer un dispositif de commande (11) qui soit compact. A cet effet, ledit dispositif de commande (11) comprend un mécanisme bielle-manivelle oscillant (14) guidé dans le sens de levée (flèche 'B') de la soupape par l'intermédiaire d'une première articulation coulissante-pivotante (12) placée côté carter et par l'intermédiaire d'une autre articulation coulissante-pivotante (13) placée côté segment de basculement. Ce mécanisme bielle-manivelle oscillant (14) comprend une ouverture de commande (15) traversée avec un jeu par une partie de l'arbre à cames (4) dépourvue de came de commande. Un élément (bague de guidage 20), pouvant être actionné de manière commandée par un dispositif de réglage (16) qui est placé dans ou sur l'arbre à cames (4) de façon à entraîner ce dernier, vient en contact avec la périphérie de cette ouverture (15) de sorte que, lors de la rotation de l'arbre à cames (4), à chaque levée de soupape, le mécanisme bielle-manivelle oscillant (14) effectue un mouvement oscillant périodique, servant à la commande desmodromique du segment de basculement (5).
