Abstract

Ce mécanisme comprend une roue dentée 72 qui est montée sur l'arbre d'entrée 30 du compteur et entraîne normalement un arbre intermédiaire 42 destiné à attaquer le totalisateur 68 du compteur, par l'intermédiaire d'une came menante 56 et d'une came menée 50. Si le compteur est traversé par le gaz dans le sens inverse du sens normal (notamment par suite d'une inversion frauduleuse de l'appareil), l'arbre 30 tourne en sens inverse et la face arrière 86 de la came 56 repousse la face arrière 54 de la came 50 axialement pour dégager les deux cames l'une de l'autre et mettre la came 90 solidaire de la came 50 en prise avec une autre came 88 entraînée dans le sens inverse de la rotation de l'arbre 30 par des roues dentées de renvoi 74, 78, 80, de sorte que le totalisateur 68 est toujours entraîné dans le même sens.
