Abstract

A valve device for a fuel injection valve (1), wherein the intersection point (13c) between the center line Z of the valve seat (11) and the apex of a hypothetical cone (13b) formed by extending a seating surface (13) toward the downstream side is positioned inside an aperture (15). Thus, after most of the fuel that has passed through a seat part (13a) converges at the aperture (15), the fuel reaches the upper surface of an injection hole plate (22) and smoothly changes to a flow toward the outer circumferential side, thereby minimizing the fuel pressure loss in this interval. Therefore, in this valve device for the fuel injection valve (1), a decrease in the fuel speed in the section (22b) directly above the injection hole is reduced, and atomization of the fuel spray is promoted.
