Claims (1)
アダプタを設けた燃料噴射弁であつて、 前記のアダプタはノズルボデーの噴射孔の外周
部分を覆い、かつこの噴射孔を中心とする円形の
中心孔を有する先端部を備え、 この先端部の肉厚を前記噴射孔の内径の１．５
〜３倍の寸法に設定するとともに、 前記中心孔の内径を同じく噴射孔の内径の５〜
７倍の寸法に設定した燃料噴射弁。[Scope of Claim for Utility Model Registration] A fuel injection valve having an adapter provided on the outer periphery of a nozzle body having a fuel injection hole, wherein the adapter covers the outer periphery of the injection hole of the nozzle body and covers the injection hole. The tip has a circular center hole at the center, and the wall thickness of this tip is 1.5 of the inner diameter of the injection hole.
The inner diameter of the center hole is set to ~3 times the inner diameter of the injection hole.
Fuel injection valve set to 7 times the size.
