Title
(EN) FUEL INJECTOR WITH AN INTERNAL PUMP
(FR) INJECTEUR DE CARBURANT A POMPE INTEGREE
Abstract
(EN)
A fuel injector (14) that has an integral hydraulically driven mechanically actuated dual action intensifier (12) and a solenoid control valve (16)/spring assembly (138) that accurately controls the movement of the injector intensifier piston (132, 134), and the amount and timing of fuel ejected by the injector (14).
(FR)
Un injecteur de carburant (14) comporte un auxiliaire intégré à double action, à commande mécanique et entraînement hydraulique (12), et un ensemble soupape de commande à solénoïde (16)/ressort (138) qui commande avec précision le déplacement du piston d'auxiliaire d'injection (132, 134) ainsi que la quantité et l'instant de l'injection de carburant par l'injecteur (14).
