Abstract

LE SYSTEME COMPORTE UNE POMPE BASSE PRESSION 30 FOURNISSANT DU COMBUSTIBLE A UNE POMPE HAUTE PRESSION. CELLE-CI COMPORTE UN DISTRIBUTEUR 11 MOBILE AXIALEMENT SOUS L'ACTION D'UNE PRESSION APPLIQUEE A UN SERVO-REGULATEUR 32 ET DONT LA POSITION AXIALE DETERMINE LA QUANTITE DE COMBUSTIBLE FOURNIE. IL Y EST PREVU UN PISTON 55 DE SYNCHRONISATION DE LA POMPE, DONT LA POSITION AXIALE EST DETERMINEE PAR LA PRESSION APPLIQUEE A UN SERVO-REGULATEUR 54. UN SYSTEME DE COMMANDE COMPORTE DES CLAPETS 59 ET 58 POUR COMMANDER LA PRESSION DES REGULATEURS. LE SYSTEME DE COMMANDE EST ELOIGNE DE LA POMPE ET LES PRESSIONS DE COMMANDE PASSENT PAR DES CANALISATIONS 63, 70. DES TRANSDUCTEURS 68, 69 FOURNISSENT DES SIGNAUX ELECTRIQUES REPRESENTATIFS DES PRESSIONS DE COMMANDE.
