Abstract: A method of generating a spray by a fluid injection valve is provided. The fluid injection valve includes a valve seat (10), a valve body (8), and an orifice plate (11) having a plurality of orifices (12). 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 (30), (31) from the respective orifices (12) 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 (12) 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.
Abstract translation: 提供了一种通过流体注射阀产生喷雾的方法。 流体喷射阀包括阀座（10），阀体（8）和具有多个孔（12）的孔板（11）。 孔口中的流动以及直接在孔口下方的流动被构造成基本上是液体膜流。 来自各个孔口（12）的喷流（30），（31）的方向不一定与孔口的中心轴线方向一致，并不一定在其下游位置彼此相交。 在从喷孔（12）喷射流动到比分解长度（a）更远的下游位置喷雾时，喷雾剂被作用在多个喷雾上的柯安达效应会聚。 喷雾剂的融合持续进行，直到柯恩达效应显着丧失。

Abstract: A fuel injection valve includes a valve seat portion, a nozzle hole plate, and a valve member. The valve seat portion has an inner circumferential surface including a valve seat. The nozzle hole plate is disposed at a downstream side of a fuel passage of the valve seat. The nozzle hole plate has a nozzle hole for injecting fuel flowing out from the fuel passage. The valve member seats on the valve seat to close the fuel passage and unseats from the valve seat to open the fuel passage. Diameter of the inner circumferential surface decreases as approaching to a downstream side. The nozzle hole of the nozzle hole plate is formed so that length of radial outside of the nozzle hole with respect to a shaft center of the fuel injection valve is smaller than that of radial inside of the nozzle hole.

Abstract: An improved fuel injection valve for improving the flow of fuel includes a vortex forming member and a needle valve having a planar surface on its leading end. A valve seat has a fuel injection nozzle formed therein and the needle valve opens and closes the fuel injection nozzle by engaging and disengaging with the valve seat. The vortex forming member provides a vortex motion to the fuel entering the fuel injection nozzle, upstream of a seat portion. The flat portion reduces the amount of surface area in which particles may adhere, thus preventing particles from adhering to the needle valve and reducing interference with the flow of fuel.
