| description | To close a pressure control chamber securely when electricity transmission to an injector ends to prevent deterioration of fuel consumption of an internal combustion engine.SOLUTION: An injector includes: an electromagnet which attracts an armature when energized; a valve spring which presses the armature in a direction away from the electromagnet; a valve body having a pressure control chamber which presses a nozzle needle in a direction such that the nozzle needle closes a fuel injection hole; a valve ball 67 which may close the pressure control chamber by a pressing force of the valve spring; and a ball holder 68 disposed between the armature and the valve ball 67. The ball holder 68 includes rotational force generation parts 90 for rotating the ball holder 68 around a center axis Z of the ball holder 68 by flow of a fuel flowing out from the pressure control chamber when the electromagnet is energized.SELECTED DRAWING: Figure 5
【課題】インジェクタへの通電終了時に圧力制御室を確実に閉鎖し、内燃機関の燃費の悪化を防ぐ。【解決手段】インジェクタは、通電時にアーマチュアを引き付ける電磁石と、アーマチュアを電磁石から遠ざかる方向へ押圧するバルブスプリングと、燃料噴射孔を閉鎖する方向へノズルニードルを押圧する圧力制御室を有するバルブボディと、バルブスプリングの押圧力により圧力制御室を閉塞可能なバルブボール６７と、アーマチュアとバルブボール６７との間に配置されるボールホルダ６８と、を備え、ボールホルダ６８は、電磁石への通電時に圧力制御室から流出する燃料の流れにより、ボールホルダ６８をボールホルダ６８の中心軸Ｚ周りに回転させるための回転力発生部９０を備える。【選択図】図５ |
