Abstract

L'invention a trait à un circuit de fluide sous pression pour une transmission composite hydrodynamique-mécanique. Elle a pour objet un circuit dans lequel la pression d'entrée de l'élément hydrodynamique peut être régulée dans une large mesure, indépendamment du débit de la source de fluide sous pression et dans lequel la partie du débit du fluide de la source à aspirer à travers le filtre peut être réduite. Application notamment aux transmissions du type hydrodynamique-mécanique.
