Abstract

Ce dispositif de commande pour transmission ou changement de vitesse hydrostatique entraîné par un moteur à combustion interne comprend deux circuits de mesure dont les principaux éléments sont deux étranglements 55 et 59, dont l'un, 55, est conjugué au moteur (papillon 50), l'autre à la transmission (pompe hydraulique réglable 11). La différence de pression sur l'étranglement 55 augmente proportionnellement à la vitesse de rotation du moteur et il s'établit une vitesse définie lorsque le papillon 50 est fermé de manière que le moteur puisse encore << tirer >> tout juste le couple de charge produit par la transmission.
