Abstract

POMPE D'INJECTION DE COMBUSTIBLE POUR MOTEUR A COMBUSTION INTERNE, DU TYPE COMPRENANT UN CORPS, UN ROTOR MONTE DANS LE CORPS, ENTRAINE EN SYNCHRONISME AVEC LE MOTEUR ASSOCIE, AU MOINS UN ELEMENT DE POMPAGE PORTE PAR LE ROTOR, UNE BAGUE MOBILE ANGULAIREMENT ENTOURANT LE ROTOR, DES MOYENS PREVUS SUR LA BAGUE POUR DEPLACER L'ELEMENT DE POMPAGE EN VUE DE L'INJECTION DE COMBUSTIBLE LORSQUE LE ROTOR TOURNE, UN PISTON LIE A LA BAGUE ET MONTE COULISSANT PAR RAPPORT AU CORPS, LEQUEL PISTON EST SOUMIS A UNE PRESSION DE FLUIDE QUI VARIE AVEC LA VITESSE DU MOTEUR, ET UN RESSORT PRENANT APPUI SUR LE CORPS ET AGENCE POUR S'OPPOSER AU DEPLACEMENT DU PISTON SOUS L'ACTION DE LADITE PRESSION. IL EST PREVU UNE COUPELLE 25 INTERPOSEE ENTRE LE RESSORT 26 ET LE PISTON 16, UNE TIGE 29 COMPORTANT UNE SURFACE DE RETENUE 30 POUR DEFINIR LA POSITION EXTREME DE LA COUPELLE, LA TIGE ETANT COULISSANTE PAR RAPPORT AU CORPS 15, ET UN ORGANE DE MANOEUVRE 34 POUR DEFINIR LA POSITION AXIALE DE LA TIGE 29.
