FUEL INJECTION VALVE AND INJECTION HOLE PLATE

PROBLEM TO BE SOLVED: To atomize fuel.SOLUTION: In a fuel injection valve for injecting fuel, there is included a plate-shaped injection part for injecting the fuel supplied from one face side to the other face side. The injection part includes an injection hole for penetrating the other face side from the one face side and for injecting the fuel, and a recess for leading the fuel from the upper stream to the downstream injection hole. The recess includes: a branch part for receiving the fuel; a cylindrical part for surrounding the injection hole and pivoting the fuel; an arcuate pivoting part extended along an outer circumference of the cylindrical part; a belt-shaped first introduction part connected to the branch part and the cylindrical part and introducing the fuel received from the branch part to the cylindrical part toward the first direction of introduction; and a belt-shaped second introduction part being added to the first introduction part, connected to the first introduction part and the branch part, and introducing the fuel received from the branch part to lead to the pivoting part toward the second direction of introduction being parallel in the first direction of introduction. The pivoting part makes the fuel flow direction where the fuel introduced by the second introduction part flows into the cylindrical part face the fuel flow direction where the fuel introduced by the first introduction part flows into the cylindrical part.SELECTED DRAWING: Figure 1 【課題】燃料の微粒化を図る。【解決手段】燃料を噴射する燃料噴射弁において、一面側から供給された燃料を他面側へ噴射するプレート状の噴射部位を備え、噴射部位は、一面側から前記他面側に貫通し、燃料を噴射する噴孔と、燃料を上流から下流の噴孔へ導く窪み部とを備え、窪み部は、燃料を受け付ける分岐部と、噴孔を囲い燃料を旋回させる円筒状の円筒部と、円筒部の外周に沿って延設してある弧状の旋回部と、分岐部および円筒部に接続してあり、分岐部が受け付けた燃料を第１導入方向に向かって円筒部に導く帯状の第１導入部と、第１導入部に併設してあり、第１導入部および分岐部に接続し、分岐部が受け付けた燃料を第１導入方向に平行な第２導入方向に向かって旋回部に導く帯状の第２導入部とを備え、旋回部は、第２導入部によって導かれた燃料が円筒部に流れ込む燃料流方向を、第１導入部によって導かれた燃料が円筒部に流れ込む燃料流方向に対向させる。【選択図】図１
