Abstract: An engaging projection of a valve body engages with an interlocking groove of a nozzle plate and the nozzle plate is rotated relative to the valve body. The engaging projection moves in a lateral groove of the interlocking groove while elastically deforming an arm part (elastically deformable portion), and the engaging projection is accommodated in a recess (lock position in the interlocking groove) of the arm part. A bottom surface of the recess of the arm part is pushed against the engaging projection of the valve body by the elastic force of the arm part, and the engaging projection of the valve body is seated and fixed on the bottom surface of the recess of the arm part. Accordingly, the nozzle plate is fixed to the valve body while being retained via the engaging projection and the interlocking groove (interlocking means).

Abstract: Fuel flows from first and second fuel guide channels into the swirl chamber and is guided to the nozzle hole while swirling in the swirl chamber in the identical direction. The nozzle hole is divided into an inlet portion near a fuel-inflow end and an outlet portion near a fuel-outflow end. The outlet portion has a flow passage cross-sectional area gradually increasing towards a fuel outflow-side opening end, and includes a curved surface formed by smoothly connecting an inner surface of the nozzle holes at an upstream end side in a fuel flow direction to an inner surface of the nozzle holes at the portion near the fuel-inflow end so as to smoothly and gradually increase the flow passage cross-sectional area. The curved surface ensures further thin film-like flow by expanding a flow of the fuel in the nozzle holes by the Coanda effect.
