ABSTRACT:
A fluid injection nozzle is used with a fuel injection valve of an internal combustion engine and is capable of controlling its fluid injection angle to a desired value when the fluid is atomized for injection. The fluid injection nozzle is fixed to the outlet portion of the injection port of the fuel injection valve and includes a first orifice plate having a first orifice and a second orifice plate having a second orifice. The first and second orifice plates are laid one above another so that the first and second orifices intersect each other to provide a through-hole in the direction of thickness of the plates. With such an arrangement, the fuel injection angle of the nozzle is controlled on the basis of the ratio of the area of intersection of the downstream side opening surface of the first orifice with the upstream side opening surface of the second orifice with respect to the area of the downstream side opening surface of the second orifice.
