Abstract

　構成部品点数を減らし、フィルタのずれや脱落のおそれを解消できるとともに、弁部材の着座時の打音を低減できるようにした燃料噴射弁を提供する。 　先端に開口部を有するバルブボディと、バルブボディ内を摺動しバルブボディの開口部を開閉する弁部材と、弁部材が固定されたアーマチュアと、アーマチュアを開口部側へ付勢するスプリングと、スプリングの付勢力に抗してアーマチュアを開口部側とは反対側へ移動させる電磁ソレノイドと、を備え、電磁ソレノイドに電流を供給しアーマチュアを移動させることにより燃料を噴射する燃料噴射弁であって、アーマチュアは多孔質金属材料からなり、噴射孔側に供給される燃料がアーマチュアを透過するように構成される。
