Abstract
LA INVENCION SE REFIERE A UN DISPOSITIVO DE INYECCION DE COMBUSTIBLE CON UNA CONDUCCION DE AFLUENCIA DE COMBUSTIBLE, UN PRIMER ELEMENTO DE BOMBEO MECANICO Y UNA TOBERA DE INYECCION DE COMBUSTIBLE. ENTRE EL ELEMENTO DE BOMBEO MECANICO Y LA TOBERA DE INYECCION DE COMBUSTIBLE SE DISPONE DE UNA VALVULA DE CONTROL CONTROLADA ELECTRONICAMENTE Y ENTRE LA VALVULA DE CONTROL Y LA TOBERA DE INYECCION SE DISPONE UN SEGUNDO ELEMENTO DE BOMBEO, QUE SE UNE A TRAVES DE UNA SEGUNDA CONDUCCION DE AFLUENCIA DE COMBUSTIBLE CON UNA APLICACION DE RESERVA DE COMBUSTIBLE.THE INVENTION REFERS TO A FUEL INJECTION DEVICE WITH A FUEL LUBRICATION DRIVING, A FIRST MECHANICAL PUMPING ELEMENT AND A FUEL INJECTION NOZZLE. BETWEEN THE MECHANICAL PUMPING ELEMENT AND THE FUEL INJECTION NOZZLE IT HAS AN ELECTRONICALLY CONTROLLED CONTROL VALVE AND BETWEEN THE CONTROL VALVE AND THE INJECTION NOZZLE A SECOND PUMP ELEMENT IS DISPOSED, THAT JOINS THROUGH A SECOND FUEL FLOW WITH A FUEL RESERVE APPLICATION.
