Abstract

Le convertisseur comporte un plateau d'embrayage 40 qui est serré contre la coquille d'entrée 14 par la différence de pression entre des chambres d'embrayage 76 et de débrayage 78. Une soupape 62 normalement ouverte, sensible à la force centrifuge, est montée dans le plateau 40 pour faire communiquer entre elles les deux chambres et permettre le patinage de l'embrayage jusqu'à ce que le plateau atteigne une vitesse prédéterminée, et une seconde soupape 64 sensible à la force centrifuge normalement fermée, est egalement montée dans le plateau 40 pour faire communiquer entre elles les deux chambres en réponse à la vitesse du plateau et à la différence de pression entre les chambres afin de commander la force de serrage de l'embrayage lorsque la vitesse du plateau est égale ou supérieure à la vitesse prédéterminée de façon que cette force soit à peu près égale à la valeur requise par la charge du véhicule. L'invention est applicable aux convertisseurs de couple pour automobiles.
