Abstract

L'invention se rapporte à un procédé et à un dispositif de commande de soupape pour moteur à combustion interne. Selon l'invention on interpose entre le poussoir 5 et le ressort de rappel 18 un dispositif différentiel de transmission hydraulique comprenant un piston flottant 12 qui se déplace dans une chambre 10 dans laquelle est ménagée une section supérieure réduite autour d'un piston fixe 4 et une section inférieure élargie, ce dispositif différentiel permettant de réduire la déflexion du ressort 18 pour une même levée de soupape. L'invention s'applique notamment aux moteurs à combustion interne évitant l'affolement des soupapes aux régimes de fonctionnement élevés du moteur.
