Abstract

L'objectif de la présente invention est de fournir un moteur SOHC à cylindre unique de taille réduite en augmentant le degré de liberté dans la conception du moteur tout en empêchant une augmentation de perte mécanique. Un culbuteur d'admission (32) et un culbuteur d'évacuation (33) présentent respectivement des surfaces coulissantes (46, 56) qui présentent une largeur dans la direction de l'axe de rotation (C2) d'un arbre à cames (31) qui est inférieure à la largeur (D2) des parties d'extrémité (44a, 54a) des parties levier à came (44, 54) à proximité des parties bossage (43, 53), lesdites surfaces coulissantes coulissant respectivement par rapport à une came d'admission (40) et une came d'évacuation (41) par le biais d'un revêtement présentant un coefficient de frottement inférieur et une dureté supérieure à ceux du matériau de base des surfaces coulissantes. Les surfaces coulissantes (46, 56) sont agencées sous la forme d'une rangée dans la direction de l'axe de rotation (C2) de l'arbre à cames (31).
