Combination of a fuel injection valve and a nozzle

摘要

In a nozzle of an electromagnetic fuel injection valve, the nozzle comprises a columnar body extending forwardly from the front end of the valve body, a plurality of fuel atomizer holes formed in the columnar body on a circle about an axis of the columnar body in equally spaced relationship with each other, the fuel atomizer holes being outwardly inclined in accordance with the direction of fuel atomization, a conical portion formed at an axial portion of the columnar body in such a manner as to be surrounded by the fuel atomizer holes, and a fuel distributing portion formed at the top of the conical portion for atomizing the liquid fuel columnarly injected from the valve body, the fuel distributing portion having a predetermined sectional area in a direction perpendicular to the axis of the columnar body whereby the liquid fuel atomized in the nozzle is supplied to a predetermined circular area at a fixed distance.
