Abstract

In a valve device for a fuel injection valve (1), an intersection point (13c) between a vertex of an imaginary cone (13b), which is obtained by extending a seat surface (13) to a downstream side, and a center axis Z of the valve seat (11) is located in an opening (15). In this way, most of fuel that has flowed along a seat section (13a) is collected at the opening (15), then reaches an upper surface of an injection hole plate (22), and is smoothly shifted to become a flow toward an outer circumferential side. Thus, pressure loss of the fuel during this process is suppressed to be small. Therefore, in the valve device for the fuel injection valve (1), a reduction in a fuel speed in a section (22b) right above an injection hole is suppressed, and atomization of fuel spray is promoted.
