Abrégé
(EN) A fuel injection valve (1A) comprises: a needle (3) which is contained in a valve body (2) so as to be able to reciprocate; a nozzle plate (4) which is mounted to the front end (2a) of the valve body (2) and in which nozzle holes (7) communicating with the inside and outside of the valve body (2) are formed; and a valve seat (6) on which the needle (3) is seated and unseated so that a fuel flow path (10) which leads to the nozzle holes (7) of the nozzle plate (4) through the outer periphery of the needle (3) can be closed and opened. The nozzle plate (4) has formed therein a recess (15) which is recessed in the direction of the axis of the needle (3) so as to cause the fuel, which flows toward the nozzle holes (7) after passing through the valve seat (6), to descend along the nozzle plate (4) from the level of the inlets (20) of the nozzle holes (7), ascend, and then reach the inlets (20) of the nozzle holes (7).
(FR) Une soupape d'injection de carburant (1A) comprend : une aiguille (3) qui est contenue dans un corps de soupape (2) de manière à pouvoir effectuer un mouvement alternatif ; une plaque à buses (4) qui est montée sur l'extrémité avant (2a) du corps de soupape (2) et dans laquelle des trous de buse (7) communiquant avec l'intérieur et l'extérieur du corps de soupape (2) sont formés ; et un siège de soupape (6) sur lequel l'aiguille (3) est supportée et libérée de sorte qu'un trajet d'écoulement à travers toute la périphérie externe de l'aiguille (3) puisse être fermé et ouvert. La plaque à buses (4) comprend un évidement (15) formé à l'intérieur de celle-ci qui est évidé dans la direction de l'axe de l'aiguille (3) afin d'amener le carburant, qui s'écoule en direction des trous de buse (7) après avoir traversé le siège de soupape (6), à descendre le long de la plaque à buses (4) depuis le niveau des admissions (20) des trous de buse (7), à monter, puis à atteindre ensuite les admissions (20) des trous de buse (7).
(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。
