Abstract

LE SYSTEME D'ALIMENTATION EN FLUIDE MOTEUR SELON LA PRESENTE INVENTION COMPREND DES PREMIERE ET SECONDE POMPES D'ALIMENTATION 186, 192, UN APPAREIL 10 D'AMPLIFICATION D'ENERGIE HYDRAULIQUE, UN DISPOSITIF 212 DE DIRECTION ASSISTEE, DIVERS PASSAGES DE FLUIDE SE RACCORDANT A CES DERNIERS ET UN APPAREIL DE COMMANDE 202, 216, 218, LA PREMIERE POMPE FOURNIT LE FLUIDE SOUS PRESSION A UNE PREMIERE LUMIERE D'ENTREE 94 DE L'APPAREIL D'AMPLIFICATION. LA SECONDE POMPE, COMMANDEE PAR L'APPAREIL DE COMMANDE, FOURNIT SELECTIVEMENT LE FLUIDE SOUS PRESSION A UNE SECONDE LUMIERE D'ENTREE 192 DE L'APPAREIL D'AMPLIFICATION POUR MAINTENIR LE DEBIT DU FLUIDE APPLIQUE A CE DERNIER SENSIBLEMENT CONSTANT A UN NIVEAU PREDETERMINE QUAND LE DEBIT DE DECHARGE DU FLUIDE DE LA PREMIERE POMPE EST INFERIEUR A SON NIVEAU PREDETERMINE. DE CETTE FACON, UNE QUANTITE SUFFISANTE DE FLUIDE EST FOURNIE A L'APPAREIL D'AMPLIFICATION POUR QU'IL FONCTIONNE PARFAITEMENT A TOUTES LES VITESSES REELLES DU MOTEUR. PAR CONTRE, LE FLUIDE FOURNI PAR LA SECONDE POMPE NE PEUT S'ECOULER DANS LE DISPOSITIF DE DIRECTION ASSISTEE GRACE AUDIT AGENCEMENT DE VALVE DE COMMANDE.
