Abstract

L'INVENTION CONCERNE UN APPAREIL HYDROSTATIQUE DE COMMANDE DE DIRECTION COMPORTANT A CERTAINES POSITIONS DE SES ELEMENTS DE DISTRIBUTION UNE RETENUE DE PRESSION QUI EVITE LES FUITES DE FLUIDE A HAUTE PRESSION. IL COMPREND DEUX ELEMENTS DE DISTRIBUTION POUVANT SE DEPLACER L'UN PAR RAPPORT A L'AUTRE EN SENS OPPOSES D'UNE POSITION NEUTRE VERS DEUX POSITIONS DE FONCTIONNEMENT DANS LESQUELLES ILS COMMANDENT L'ECOULEMENT DU FLUIDE ENTRE UNE SOURCE ET UN MOTEUR HYDRAULIQUE DE DIRECTION. DES SURFACES DE CES ELEMENTS DELIMITENT PARTIELLEMENT UN PREMIER CONDUIT DIRIGEANT LE FLUIDE A HAUTE PRESSION VERS LE MOTEUR ET UN SECOND CONDUIT DIRIGEANT LE FLUIDE A BASSE PRESSION DU MOTEUR VERS UN RESERVOIR. CES SURFACES SONT DISPOSEES DE FACON A CONSTITUER UNE RETENUE DE PRESSION ENTRE LES PREMIER ET SECOND CONDUITS LORSQUE LES ELEMENTS DE DISTRIBUTION SE DEPLACENT L'UN PAR RAPPORT A L'AUTRE D'UNE DISTANCE PREDETERMINEE DE LEUR POSITION NEUTRE A UNE POSITION DE FONCTIONNEMENT. APPLICATION A LA DIRECTION ASSISTEE DE VEHICULES A MOTEUR.
