Claims (1)
ルボデーと、前記噴口を開開し噴口との間に噴口間隙を
形成するべく前記貫通孔内に軸方向運動可能に嵌挿され
た針弁、とを具備して成るディーゼルエンジン用燃料噴
射弁のビントル型もしくはスロットル型ノズルに於て、
ノズルボデーの先端には針弁の非リフト時に前記噴口間
隙をノズル外部から実質的に遮断し得るような閉塞部材
を設け、該閉塞部材の中央には針弁の最大リフト時に噴
口間隙により決定される噴口流量に実質的に影響を与え
ないような大きさの横断面積の開口゛ を針弁およ
び噴口と整列して設けたことを特徴とするノズル。a nozzle body having a through hole that partially includes a nozzle extending in the axial direction, and a needle inserted and inserted into the through hole so as to be movable in the axial direction to open the nozzle and form a nozzle gap between the nozzle and the nozzle. In a bottle-type or throttle-type nozzle of a diesel engine fuel injection valve comprising a valve,
A closing member is provided at the tip of the nozzle body so that the nozzle gap can be substantially blocked from the outside of the nozzle when the needle valve is not lifted, and the center of the closing member is determined by the nozzle gap when the needle valve is at its maximum lift. 1. A nozzle characterized in that an opening is provided in alignment with a needle valve and a nozzle and has a cross-sectional area of a size that does not substantially affect the flow rate of the nozzle.
