ABSTRACT:
A fuel injector nozzle comprising an inner member including an axially extending fuel passage adapted to communicate with a source of fuel under pressure and having an outlet end with a surface defining a valve seat, and an outer surface extending axially outwardly and converging to the valve seat, a valve member located in the fuel passage and movable axially thereof relative to the valve seat between open and closed positions, which valve member includes a valve head which is engageable with the valve seat when the valve member is in the closed position and spaced from the valve seat when the valve member is in the open position, and which includes an axially outwardly extending and converging surface, and an outer member surrounding the inner member and the valve head in spaced relation thereto and defining therebetween an air flow passage adapted to communicate with a source of air under pressure, which outer member includes an axially outwardly extending and converging surface located in spaced relation to the outer surface of the inner member and to the converging surface of the valve head and forming, with the outer surface of the inner member and the converging surface of the valve head, an air flow passage portion which diverges axially outwardly and which communicates with the fuel passage when the valve seat is in the open position, which outer member also includes an annular distribution chamber forming a part of the air flow passage, and an air flow duct forming a part of the air flow passage and communicating with the distribution chamber and with the environment exterior to the outer member.
