A swirl type fuel injection valve has a bigger diameter guide expanded its diameter than the small diameter guide of the tip of a valve member and as the big diameter guide is composed of a non-magnetic member with a desired length in its axial direction, the stablization of a valve operation and the restraint of the bouncing after closing the valve are carried out. スワ−ルタイプの燃料噴射弁にあって、弁部材の先端部の小径ガイド部より拡径した一方の大径ガイド部を有し、大径ガイド部がその軸方向において所望の長さの非磁性部材よりなる様に構成し、弁動作の安定化と閉止後のバウンシングを抑制するようにした。 - 特許庁
