Abstract
A method of generating a spray by a fluid injection valve is provided. The fluid injection valve includes a valve seat (), a valve body (), and an orifice plate () having a plurality of orifices (). The flows in the orifices and the flows directly below the orifices are configured to be substantially liquid film flows. The directions of jet flows (), () from the respective orifices () are not necessarily matched to the central axis directions of the orifices and are not necessarily intersected with each other at a downstream position thereof. The sprays are caused to converge by the Coanda effect acting on a plurality of sprays after jet flows from the orifices () become sprays at a downstream position farther than a break-up length (a). The convergence of the sprays is continued until the Coanda effect is substantially lost.
