FLUID INJECTION NOZZLE AND FLUID INJECTION VALVE PROVIDED WITH THE FLUID INJECTION NOZZLE

摘要

PROBLEM TO BE SOLVED: To provide a fluid injection nozzle for promoting the atomization of a fluid and a fluid injection valve provided with the fluid injection nozzle. SOLUTION: A fuel injection nozzle 5 is provided in the main body of a fuel injection valve for injecting fuel from an injection port 3b when opened. A nozzle hole 5a consisting of an inlet hole 51a, a long hole 52a and an outlet hole 53a is furnished to stepwise control the flow direction of the fuel injected from the injection port 3b. The long hole 52a with its one end communicating with the outlet hole 53a is extended in the direction crossing the axis of the nozzle. The inlet hole 51a is communicated to the other end of the long hole 52a. The outlet hole 53a makes an acute angle with the long hole 52a.
