Abstract
Dispositif de commande de la circulation d'un fluide de la direction assistée d'un véhicule. Il comprend un distributeur qui, lorsqu'il occupe une position de repos, dirige le fluide refoulé par une pompe vers un mécanisme auxiliaire et qui, lorsqu'il occupe l'une de deux positions de commande, dirige le fluide refoulé vers une extrémité d'un cylindre commandant une direction assistée de façon à y déplacer un piston et à braquer les roues du véhicule. Le distributeur comprend un manchon rotatif comportant une série circulaire d'orifices. Un tiroir rotatif coopère avec ces orifices de façon à diriger le fluide refoulé par la pompe soit vers le mécanisme auxiliaire, soit vers le cylindre, afin de braquer les roues du véhicule. Application notamment aux véhicules de terrassement.
