FUEL INJECTION VALVE AND ITS MOUNTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection valve and its mounting method capable of reducing or removing the fuel attached to the forefront of the valve resulting from fuel spray and a suction air flow while the fuel spray is atomized. SOLUTION: The fuel injection valve is structured so that a jet plate 28 having a plurality of jets 28a is installed at the outlet from a fuel passage formed at the forefront of a valve body 29, in which the gauging of the fuel and determination of the injecting direction are made by injecting the fuel from the jets 28a, wherein the arrangement further includes a negative pressure forming part 200 to form a negative pressure with the fuel injected from the jets 28a in the downstream of near the jet plate 28 and a collecting means to guide the attached fuel through utilization of the negative pressure generated in the part 200 and form a flow of the attached fuel directed toward the outlets 281 of the jets 28a.
