Abstract

Ce dispositif de commande comprend un culbuteur (18), monté articulé sur un support (14), autour d'un premier axe d'oscillation fixe (F1), muni d'un premier bras (18A) sollicitant l'extrémité libre de la queue (20) de la soupape (12) et d'un second bras (18B) sollicité par une came de commande rotative (22), et des moyens (28, 34) de réglage de la levée de la soupape, comprenant un organe de réglage (28), monté articulé sur le second bras (18B) du culbuteur autour d'un axe d'oscillation mobile (M1), un premier galet (30) de contact avec la came de commande (22), lequel est monté articulé sur l'organe de réglage (28) autour d'un premier axe de rotation mobile (R1), et un second galet (32) de contact avec une came de réglage (34), lequel est monté articulé sur l'organe de réglage (28) autour d'un second axe de rotation mobile (R2). La came de réglage (34) est montée articulée sur le support (14) autour d'un second axe d'oscillation fixe (F3) sensiblement parallèle au premier axe d'oscillation fixe (F1) de sorte que, pour une position constante de la came de commande (22) correspondant à une position de la soupape (12) où celle-ci est ouverte, les déplacements de cette came de réglage (34) fassent varier la distance entre le premier axe d'oscillation fixe (F1) et le second axe de rotation mobile (R2).
