Abstract

Suiveur de came de type levier destiné à une distribution à soupapes d'un moteur à combustion interne, comprenant un corps de base (3) allongé se composant de deux parois latérales (4) qui sont reliées par un étrier transversal (5). L'étrier transversal (5) présente sur son côté inférieur au niveau d'une première section d'extrémité (6), une surface d'appui (9) destinée à un élément de butée, et au niveau d'une deuxième section d'extrémité (8), une surface de contact (11) destinée à une extrémité de tige de soupape d'une soupape d'échange des gaz. L'étrier transversal (5) présente dans une section (7) proche de son centre, une surface d'attaque (14) formée par un galet de came (13). Le corps de base (3) est extrudé. Dans l'étrier transversal (5) est formée une unique demi-coquille (12) destinée à loger le galet de came (13). La demi-coquille (12) est ouverte dans un sens opposé à la soupape d'échange des gaz.
