Fluid injection nozzle

According to the present invention, an injection nozzle of the fuel injection valve has an orifice plate (52). A needle (25) and the orifice plate (52) are arranged such that a flow directed uniformly toward the orifice plate (52) is induced in a flat flow passage between a needle flat surface (82)...

Beschreibung
Zusammenfassung:	According to the present invention, an injection nozzle of the fuel injection valve has an orifice plate (52). A needle (25) and the orifice plate (52) are arranged such that a flow directed uniformly toward the orifice plate (52) is induced in a flat flow passage between a needle flat surface (82) and the orifice plate inlet surface (52a), and the fuel flows collide with each other just above the orifice inlet and then the fuel is injected from the orifice plate (52). Accordingly, the internal energy of the fuel can be effectively taken out in a form of disturbance of collision, the fuel can be effectively changed into fine particles, and at the same time the fuel atomization having a superior directional characteristic can be obtained.
