Abstract

L'invention porte sur un embrayage de type pompage pour véhicule. Il est caractérisé en ce qu'il comprend une pompe à engrenages reliée au volant du moteur, en ce que le boîtier renferme un jeu d'engrenages à dents internes, en ce que des blocs supérieur et inférieur de forme croissante sont placés dans l'espace faisant face à l'endroit où les deux engrenages sont en prise. On prévoit également une soupape de commande centrifuge, un robinet de sectionnement, un bloc de formation de pression et un ressort de rappel qui se trouve sur le bloc inférieur de forme croissante. L'embrayage fonctionne sans à-coups et ne provoque aucune usure abrasive relative, de plus il est en mesure d'améliorer l'efficacité de la transmission et la consommation de combustible, etc.
