Abstract

PURPOSE: To accelerate flow of fuel and its atomization, by introducing the fuel to the upper part of an orifice tangentially from a peripheral fuel sump when a spherical valve of a fuel injection nozzle is released.
CONSTITUTION: An injector 2 comprises a core 10 having a coil 18, a movable- valve composed of a plunger 9 having a spherical valve 7 on its end, and a nozzle 21 whose orifice on its end projects within a throttle body 1. The spherical valve 7 is arranged in such a manner as to be buttable against a conical seat portion 14, while a tangential hole 28 in a tangential direction communicating with a peripheral fuel sump 4 is opened just on the upper side of the seat portion 14. Therefore, when the spherical valve 7 is released, the fuel within the sump may be ejected through the hole 28 and be injected from the orifice 11.
