Abrégé
(JA)

燃料噴射弁(1A)は、バルブボディ(2)に往復動可能な状態で収納されたニードル(3)と、バルブボディ(2)の先端部(2a)に装着され、バルブボディ(2)の内外に通じる噴孔(7)が形成された噴孔プレート(4)と、ニードル(3)の外周を経由して噴孔プレート(4)の噴孔(7)に至る燃料流路(10)を閉鎖及び開通できるようにニードル(3)が着座及び離座するバルブシート(6)と、を備え、噴孔プレート(4)には、バルブシート(6)を通過して噴孔(7)に向かう燃料が噴孔プレート(4)上で噴孔(7)の入口(20)の高さよりも下降してから上昇に転じて噴孔(7)の入口(20)に至るように、ニードル(3)の軸線方向に関して凹んだ凹部(15)が形成されている。
