Abstract

Dispositif de direction hydrostatique comprenant une soupape de commande dirigeant le fluide sous pression fourni par une pompe en fonction de la direction suivie à un moteur de direction, et un tiroir de soupape dans un carter fixe qui peut être réglé au moyen d'un volant de direction et ramené à sa position initiale au moyen du rotor d'un moteur intégrateur traversé par le fluide sous pression. Le dispositif est constitué par un mécanisme à roue planétaire dont les trois parties, à savoir la roue solaire 11, la couronne dentée 9 et la fixation de la roue planétaire 17 sont reliées respectivement au volant de direction 7, au tiroir constitué sous forme d'un tiroir rotatif 15 et au rotor 13 du moteur intégrateur 6.
