Abstract

PURPOSE: To prevent the dripping of fuel in a hole-type fuel injection valve of a diesel engine by providing arc-curved guide faces at the top of a needle valve inserted into the main body of a nozzle.
CONSTITUTION: At the top of nozzle main body 1 of a fuel injection valve, a plurality of injection holes 2a, and 2a' are radially opened, and in the main body 1, a needle valve 5 with taper faces 4 is arranged to be moved upward and downward. Taper faces 4 of the valve 5 is provided with arc-curved guide faces 10 at the top and a space 9 between a concave face 11 on the front and an end face 13 of the main body 1. The lower end of the guide face 10 is terminated at the position of the injection hole 2a to form an anti-fuel-dripping end 12. Namely, the fuel brought down to this end 12 is directly transmitted to the injection hole 2a.
