Abstract
La présente invention concerne un moteur à combustion interne comprenant au moins un cylindre (10, 12, 14, 16) comportant des moyens d'admission avec une soupape d'admission (22), des moyens d'échappement avec une soupape d'échappement (32), et des moyens de contrôle (40, 42) en ouverture/fermeture des soupapes, lesdits moyens de contrôle comportant des moyens de commande (44) et des moyens de transmission de mouvement et d'effort (56) entre lesdits moyens de commande et la soupape à contrôler.The present invention relates to an internal combustion engine comprising at least one cylinder (10, 12, 14, 16) having intake means with an intake valve (22), exhaust means with an exhaust valve (32), and control means (40, 42) for opening / closing the valves, said control means comprising control means (44) and means for transmitting movement and effort (56) between said means control and the check valve.
Selon l'invention, les moyens de transmission de mouvement et d'effort (56) comprennent un culbuteur (58) avec au moins deux basculeurs (72, 74) débrayables d'une semelle (62) contrôlant le mouvement de ladite soupape. According to the invention, the movement and effort transmission means (56) comprise a rocker arm (58) with at least two rockers (72, 74) disengageable from a sole plate (62) controlling the movement of said valve.
