Abstract

L'invention porte sur un système de commande de soupape de moteur comprenant: une soupape mobile, un doigt mobile porteur de contre-came à rouleau portant sur la soupape, une came tournante, et un doigt intermédiaire de contre-came en contact avec le doigt mobile et la came. Ledit système comporte en outre au moins un vérin coopérant avec le doigt intermédiaire et le positionnant dans deux directions par rapport à la came de manière à déplacer le doigt mobile afin d'assurer la levée et la phase voulues de la came.
