Abstract

PURPOSE: To accomplish stable fuel injection, by scraping off an intermediate portion of a nozzle needle, so as to make the contact between the nozzle needle and the nozzle body uniform and to keep normal needle motion even if some deformation is caused in the nozzle body.
CONSTITUTION: Nozzle needle 4 is fitted in body 3 which is fixed to holder 2 by means of nut 1. The nozzle needle 4 is urged by push rod 5 to close the valve, and adjacently of the nozzle needle 4, there are provided a fuel passage 6, fuel chamber 7, nozzle hole 8, etc. The top end portion and the base portion of nozzle needle 4 are shaped in conventional manner to have an outer diameter suited for tight fitting with body 3. However, its intermediate portion is shaped in the form of a neck 4' having a smaller diameter. Since, in the above arrangement, nozzle needle 4 is kept in contact with body 3 only at its top end portion and the base portion, contact between needle 4 and body 3 can be rendered uniform even if body 3 is deformed at the time when it is fixed to holder 2.
