Abstract

Le mécanisme selon l'invention comporte un culbuteur 21 pour faire fonctionner la soupape 18, telle que la soupape d'admission du cylindre, ce culbuteur comportant une rotule 23 et étant monté sur une tige de montage 25 pour pivoter normalement autour d'un point P1, le mécanisme comportant un élément en forme de godet 27 et un système de soupapes 31, 51 pour remplir la chambre 33 d'huile à partir de la pompe à huile 53 du moteur quand le cylindre doit rester en service, un anneau de commande comportant un bras 50 permettant de provoquer l'échappement de l'huile pour faire remonter le godet 27 et permettre le déplacement du point de pivotement de P1 en P2, afin que le fonctionnement du poussoir 20 fasse basculer le culbuteur autour du point P2 sans que la soupape du moteur puisse être ouverte
