摘要： PROBLEM TO BE SOLVED: To provide a fuel injection valve promoting atomization and easily controlling a fuel injection direction.
SOLUTION: By mounting a nozzle hole plate 30 to a valve body 21, a fuel chamber 50 is formed between a valve seat 23 and a nozzle hole 31. In the fuel chamber 50, the cross section perpendicular to an axis of the valve body 21 is formed to have an oval shape. Due to this, fuel flowing into the fuel chamber 50 after throttled in an opening part 22 flows along a longitudinal axis direction in the fuel chamber 50. At this time, for fuel flowing in the fuel chamber 50, velocity distribution is formed, and fuel flowing from the fuel chamber 50 to the nozzle hole 31 forms a turning flow. As a result, fuel injected from the nozzle hole 31 forms a spray in the fluid film condition. Therefore, atomization of fuel can be promoted. In addition, since fuel is injected along an inner wall of the nozzle hole plate 30 forming the nozzle hole 31, the fuel forms a spray on an extension of a center axis of the nozzle hole 31. Therefore, control of the fuel injection direction can be easily performed.

摘要翻译：要解决的问题：提供一种促进雾化并容易控制燃料喷射方向的燃料喷射阀。解决方案：通过将喷嘴孔板30安装到阀体21上，在阀座23和喷嘴孔31之间形成燃料室50.在燃料室50中，垂直于阀座阀体21形成为具有椭圆形。因此，在节流在开口部22中之后流入燃料室50的燃料沿着燃料室50的长轴方向流动。此时，燃料室50内流动的燃料形成速度分布，燃料从燃料室50流到喷嘴孔31形成转向流。结果，从喷嘴孔31喷射的燃料在流体膜状态下形成喷雾。因此，可以促进燃料雾化。此外，由于燃料沿着形成喷嘴孔31的喷嘴孔板30的内壁喷射，所以燃料在喷嘴孔31的中心轴线的延伸部上形成喷雾。因此，燃料喷射方向的控制容易执行。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device easy to work with high strength and capable of promoting atomization of fuel spray with high freedom of concentration distribution or shape change in a flat fan-like spray.
SOLUTION: An injection hole plate 20 is used in a fuel injection device for direct gasoline-injection engine. The injection hole plate 20 has five injection holes 21, 22 and 23 in total formed on the same circle. The fuel injected from the injection holes 21, 22 and 23 forms a flat fan-like spray 24. The space between the circumferentially adjacent injection holes is substantially equal, and each nozzle jet has an equal diameter. In relation to a virtual surface 90 orthogonal to the fan-like spray 24 including the central axis of the fan-like spray 24 laid along the injecting direction, the injection hole 21 is located on the virtual surface 90, and the injection holes 22 and 23 are far from the virtual surface 90 in this order and located in linearly symmetric positions having the crossing line between the injection hole plate 20 and the virtual surface 90 as the symmetric axis. The inclination of each injection hole to the virtual surface 90 is larger as each injection hole is farther from the virtual surface 90.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection device of simple structure capable of promoting the process of turning the atomized fuel into particulates.
SOLUTION: The fuel injection device is composed of a jet plate 38 having a thin portion 43 approximately in a flat form covering the opening 51 of a valve body 34 leading to a fuel passage 31 and a flat plate part 39 in a flat form having a thick portion 41 formed around the thin portion 43, and a jet hole 45 is formed in the thin portion 43. Compared with the arrangement in which the whole jet hole plate 38 of uniform thickness is made thin, this can be embodied with a shorter jet hole 45 by securing the strength of the flat plate part 39 with the thick portion 41 and thinning only the thin portion 43 while the strength of the jet hole plate 38 is well secured, so that it is possible to promote the process of turning the fuel into particulates. A supporting part to support the end face on the counter-body side of the flat plate part 39 is provided on a nozzle holder 30 accommodating the valve body 34, and thereby the jet hole plate 38 can be reinforced without increasing the number of components.
