Document Type and Number:
Japanese Patent JP3114327
Kind Code:
B2
Abstract:
PURPOSE: To provide a fuel injection valve which performs regulation of a fuel injection amount in a short time through simple processing.
CONSTITUTION: A second fuel amount regulating part 24 for performing an injection amount of fuel in a position situated upper stream from an injection nozzle 10 performs regulation of an injection amount of fuel between the guide hole 11 of the inner periphery of a valve case 7 and the amount regulating surface 23 of a flange part 21 arranged to a valve body 8. Each amount regulating surface 23 is arranged in a state to be inclined based on the axial direction of the valve body 8, and each amount regulating surface 23 is formed in the shape of a taper spread toward an upper stream. Thereby, by rotating the valve body 8 and shaving a shoulder surface 21b located upper stream from a flange part 21, a gap, simultaneously, between all amount regulating surfaces 23 and the guide hole 11 is widened and the flow passage area of a second fuel amount regulating part 24 is increased.
