摘要： [Solving Means] In a nozzle plate of the present invention, part of fuel flowing out from the fuel injection port of the fuel injection device is atomized by colliding with an interference body, is rapidly bent in a flowing direction, and collides with the fuel that is flowing straight through nozzle holes and an orifice to make the fuel flow that flows straight through the nozzle hole and orifice turbulent. The orifice includes a corner portion formed by an outer edge portion of the interference body and having a sharply pointed shape without roundness at a part of an opening edge. The corner portion makes an end portion of a liquid film of fuel passing through the orifice into a sharply pointed shape for ease of atomization by friction with air.
摘要翻译：解决方案在本发明的喷嘴板中，从燃料喷射装置的燃料喷射口流出的部分燃料通过与干涉体碰撞而雾化，在流动方向上快速弯曲，并与燃料碰撞其直接流过喷嘴孔和孔，以使直接流过喷嘴孔和孔的燃料流动紊流。孔口包括由干涉体的外缘部分形成的角部，并且在开口边缘的一部分处具有尖锐的形状而没有圆度。拐角部分使得通过孔口的燃料的液体膜的末端部分形成尖锐的形状，以便通过与空气的摩擦而易于雾化。

摘要： A nozzle hole of a nozzle plate is coupled to a fuel injection port of a fuel injection device via a swirl chamber and first and second fuel guide channels opened into the swirl chamber. The swirl chamber is formed by combining first and second elliptical-shaped recessed portions. The first fuel guide channel opens at a side of a short axis of the first elliptical-shaped recessed portion and a side of the short axis that does not overlap with the second elliptical-shaped recessed portion, and the second fuel guide channel opens at a side of a short axis of the second elliptical-shaped recessed portion and a side of the short axis that does not overlap with the first elliptical-shaped recessed portion. The first and second fuel guide channels have depths deeper than those of the swirl chamber and extend inside of the swirl chamber while gradually reducing cross-sectional areas.

摘要： This emitter (120) comprises, downstream of a first pressure reducing flow path, a discharge amount adjustment part and a discharge part. The discharge amount adjustment part communicates with the discharge part via two flow paths: a first hole (173); and a communication flow path including a second hole (174) and a second pressure reducing flow path. An irrigation liquid is supplied directly to the discharge part from the discharge amount adjustment part through the first hole (173) when the external liquid pressure is low, and supplied to the discharge part from the discharge amount adjustment part through the second hole (174) and the second pressure reducing flow path when the external liquid pressure is high.

摘要： The fuel flows from the 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 a portion near a fuel-inflow end and a portion near a fuel-outflow end. The portion near the fuel-outflow end of the nozzle holes 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.

摘要： A first compressed portion is formed by heating the plastic powder packed in a cavity of a metal mold and sintering a first portion of the plastic powder packed in the cavity in a first compression state. In addition, a second compressed portion is formed by sintering a second portion of the plastic powder packed in the cavity in a second compression state. A lot of interconnected minute voids are formed in the first compressed portion and a lot of interconnected minute voids smaller than the voids in the first compressed portion are formed in the second compressed portion. Such manufacturing work of a plastic sintered body is performed continuously in the metal mold. In addition, two types of porous portions including voids of different sizes are formed by sintering only one type of the plastic powder in the metal mold.

摘要： A nozzle plate to be attached to a fuel injection port of a fuel injection device has, in a nozzle plate main body, a nozzle hole through which fuel injected from the fuel injection port passes. Spray direction change means colliding with fuel spray injected from the nozzle hole and changing the travel direction of the fuel spray is integrally formed near an outlet of the nozzle hole of the nozzle plate main body. Accordingly, the travel direction of spray is determined by the spray direction change means according to the shape of the intake pipe, the position of an intake port, and the like.

摘要： A nozzle plate has a plurality of blades in the area that surrounds the nozzle hole on the outer plane of the bottom wall part. When the fuel is injected from the nozzle hole and the pressure in the vicinity of the nozzle hole is reduced, the plurality of blades guide a flow of air from the radially outward side of the bottom wall part to the radially inward side of the bottom wall part and generates a swirling flow of the air about the center of the bottom wall part. The swirling flow of the air about the center of the bottom wall part changes to a helical flow by receiving kinetic momentum from fine particles of the fuel injected from the nozzle hole and the helical flow of the air transports the fine particles of the fuel.

摘要： 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).
