Abstract

A.L'INVENTION CONCERNE UNE POMPE D'INJECTION DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE. B.CETTE POMPE EST CARACTERISEE EN CE QUE LE PREMIER RESSORT 24, EN TANT QUE RESSORT DE DEMARRAGE, AGIT DIRECTEMENT SUR L'ELEMENT DE REGLAGE 14 ET LE DEUXIEME RESSORT 33, EN TANT QUE RESSORT DE REGLAGE, AGIT SUR L'ELEMENT DE REGLAGE 14 EN PASSANT PAR L'INTERMEDIAIRE D'UN MANCHON FORMANT CUVETTE DE RESSORT 24, QUI S'APPUIE CONTRE LE CARTER 1, 26 DANS SA POSITION DE DEPART ET QUI EST GUIDE PAR L'ELEMENT DE REGLAGE 14. C.L'INVENTION EST APPLICABLE A L'ALIMENTATION EN CARBURANT DES MOTEURS A COMBUSTION INTERNE.A. THE INVENTION RELATES TO A FUEL INJECTION PUMP FOR INTERNAL COMBUSTION ENGINES. B. THIS PUMP IS CHARACTERIZED IN THAT THE FIRST SPRING 24, AS A STARTING SPRING, ACTS DIRECTLY ON THE ADJUSTING ELEMENT 14 AND THE SECOND SPRING 33, AS AN ADJUSTING SPRING, ACTS ON THE ADJUSTING ELEMENT 14 BY PASSING THROUGH A SLEEVE FORMING THE SPRING BOWL 24, WHICH LIES AGAINST THE CRANKCASE 1, 26 IN ITS STARTING POSITION AND WHICH IS GUIDED BY THE ADJUSTING ELEMENT 14. C. THE INVENTION IS APPLICABLE TO THE FUEL SUPPLY OF INTERNAL COMBUSTION ENGINES.
