Abstract

POMPE D'INJECTION DE SYSTEME D'INJECTION DE COMBUSTIBLE POUR MOTEUR A COMBUSTION INTERNE. LA POMPE COMPREND UN PISTON MOTEUR 28 DEPLACABLE D'UNE POSITION DE REPOS, AJUSTABLE POUR REGLER LA QUANTITE DE COMBUSTIBLE INJECTEE PAR CYCLE DANS LE MOTEUR, A UNE POSITION DE REFOULEMENT MAXIMUM FIXE, SOUS L'ACTION DE LA PRESSION D'UN LIQUIDE HYDRAULIQUE DANS UNE CHAMBRE MENAGEE DANS LE BOITIER, LE PISTON MOTEUR PROVOQUANT, PAR CE DEPLACEMENT, LE REFOULEMENT DE COMBUSTIBLE D'UNE CHAMBRE DE DOSAGE 20 ALIMENTEE PAR UNE POMPE 13 VERS AU MOINS UN INJECTEUR 11 PAR L'INTERMEDIAIRE D'UN CLAPET DE REFOULEMENT 24, ET DES MOYENS POUR FAIRE ALTERNATIVEMENT REGNER, DANS LA CHAMBRE DE COMMANDE D'INJECTION 60, UNE PRESSION DE LIQUIDE HYDRAULIQUE SUPERIEURE A CELLE FOURNIE PAR LA POMPE DE COMBUSTIBLE ET UNE PRESSION FAIBLE. APPLICATION AUX GENERATEURS A PISTONS LIBRES.
