Abstract

INJECTEUR DE COMBUSTIBLE COMPRENANT UN OBTURATEUR 12 COULISSANT DANS UN ALESAGE 11 ET ACTIONNE PAR LA PRESSION DU COMBUSTIBLE, UN PISTON 18 EN CONTACT AVEC L'OBTURATEUR 12, MONTE COULISSANT DANS UN CYLINDRE 17 DE DIAMETRE PLUS PETIT QUE L'ALESAGE 11 ET EN COMMUNICATION AVEC CELUI-CI. L'ESPACE DELIMITE PAR LE PISTON ET L'OBTURATEUR COMMUNIQUE PAR L'INTERMEDIAIRE D'UN CLAPET ANTI-RETOUR 19 AVEC L'EXTREMITE DU CYLINDRE OPPOSEE A L'ALESAGE. EN FONCTIONNEMENT, LE COMBUSTIBLE REFOULE DUDIT ESPACE PASSE PAR LE CLAPET ANTI-RETOUR ET LA PRESSION A L'EXTREMITE DU CYLINDRE OPPOSEE A L'ALESAGE AUGMENTE, CE QUI ACCROIT LA FORCE AGISSANT POUR MAINTENIR L'OBTURATEUR EN POSITION DE FERMETURE.
