Abstract

L'invention concerne un ensemble à doigt de poussée destiné à l'activation variable d'une soupape d'un moteur à combustion interne ayant un arbre à cames doté d'un moins un bossage. L'ensemble à doigt de poussée comprend un corps de poussée, un arbre, un galet de came et un mécanisme de verrouillage. Le galet de came est soutenu par l'arbre et est destiné à entrer en contact avec le ou les bossages. Le galet de came est destiné à piloter l'arbre à cames afin de conserver l'alignement du galet de came par rapport au(x) bossages. Le mécanisme de verrouillage verrouille et déverrouille sélectivement le galet de came au corps de poussée afin de conférer une première aptitude de levée de soupape et une deuxième aptitude de levée de soupape.
