Abstract

La présente invention concerne un mécanisme de soupapes destiné à des moteurs à combustion interne. Ce mécanisme comporte deux axes de culbuteur en tête de cylindre, un culbuteur supporté culbutant par ces axes de façon à relier fonctionnellement les cames d'admission et d'échappement aux soupapes d'admission et d'échappement. En l'occurrence, une plaquette à butée tourbillon (42) est serrée et fixée à une tête de cylindre (3) entre les deux axes de culbuteurs (32, 33) par un boulon de serrage (43). Des parties prenantes (42c, 42d) se formant vers l'avant dans le sens de rotation du serrage (a) de parties des deux culbuteurs (32a, 33a) formées dans les deux axes de culbuteurs (32, 33). On arrive ainsi à réaliser de façon fiable la butée tourbillon des deux axes de culbuteurs.
