摘要:
In a nozzle plate for a fuel injection device which can inject fuel flowed out from a fuel injection port of the fuel injection device in a sufficiently atomized state, a portion of fuel which flows in the inside of a nozzle hole impinges on an interference element, is sharply bent so as to flow backward by an impinging surface of the interference element which is formed of an annular recessed surface, is made to impinge on fuel which intends to advance straightly and pass through the nozzle hole and the orifice, and forms the flow of the fuel which intends to advance straightly and pass through the nozzle hole and the orifice into a turbulent flow. As a result, the nozzle plate for a fuel injection device further enhances the level of the atomization of fuel.
