ABSTRACT:
A pintle on the tip of the nozzle needle, which is disposed to be fitted through the nozzle hole of the nozzle body opening in a combustion chamber of an engine, has a conical portion. The conical portion extends along substantially the whole length of the nozzle hole when the nozzle needle has its seating portion seated on a valve seating portion of the nozzle body, and has a depth gradually decreasing toward the combustion chamber to define between itself and the nozzle needle an annular gap gradually expanding toward the combustion chamber. A portion of the pintle, which is substantially on a level with an end of the nozzle hole remote from the combustion chamber when the seating portion of the nozzle needle is in its seated position, has a diameter substantially equal to the inner diameter of the above end of the nozzle hole.
