Claims (1)
されたノズルボディと、孔内に摺動自在に収納され噴孔
を開閉する弁体と、弁体を閉弁方向に常時付勢する弾性
体と、を備えた燃料噴射弁において、前記弾性体は開弁
方向の外力を受は変形する際のバネ定数が閉弁方向の弾

とを特徴とする燃料噴射弁。A nozzle body that has a hole that communicates with the fuel pump and a nozzle hole that communicates with the hole, a valve body that is slidably housed in the hole and opens and closes the nozzle hole, and always biases the valve body in the valve closing direction. In the fuel injection valve, the elastic body has a spring constant when receiving an external force in the valve opening direction and a spring constant when deforming the elastic body, which is larger than a spring constant when generating an elastic force in the valve closing direction. A fuel injection valve featuring:
