Abstract

Régulateur de commande d'une transmission hydraulique. Il comprend un corps dans lequel tourne un ensemble de masselottes et qui contient un distributeur dont le tiroir qui commande la transmission hydraulique est relié aux masselottes de façon à être déplacé dans un premier sens à l'intérieur du corps du fait de la rotation des masselottes, un ressort poussant le distributeur de façon qu'il se déplace en sens opposé, un organe de détection d'un ralenti de la transmission comprenant des éléments hydrauliques qui, lorsque ce ralenti dépasse une vitesse prédéterminé, déplacent axialement le distributeur. Application à la régulation d'une transmission hydraulique commandant un mécanisme d'entraînement à vitesse constante.
