Abstract:
A fuel injection valve includes a valve housing having an injection hole and a valve seat surface tapering toward a downstream side, a valve component that is accommodated in the valve housing and is coaxially separated from or seated on the valve seat surface, and an elastic component biasing the valve component toward the valve seat surface. The valve component includes an inner convex surface curved in a partial spherical shape with a predetermined curvature radius, and an outer convex surface that is provided continuously to the outer peripheral side of the inner convex surface and curved in a partial spherical shape having a smaller curvature radius than the inner convex surface. A boundary portion between the inner convex surface and the outer convex surface protrudes toward the valve seat surface so as to be able to be separated from or seated on the valve seat surface.

Claim (Index 1):
A fuel injection valve, comprising:\n a valve housing having an injection hole injecting a fuel into an internal combustion engine and a valve seat surface tapering toward a downstream side on an upstream side with respect to the injection hole; a valve component which is accommodated in the valve housing, and is coaxially separated from or seated on the valve seat surface for valve opening or valve closing to allow intermittent fuel injection from the injection hole; and an elastic component biasing the valve component toward the valve seat surface, wherein the valve component includes an inner convex surface curved in a partial spherical shape with a predetermined curvature radius, an outer convex surface that is provided continuously to an outer peripheral side of the inner convex surface and curved in a partial spherical shape having a smaller curvature radius than the inner convex surface, and a boundary portion between the inner convex surface and the outer convex surface protrudes toward the valve seat surface so as to be able to be separated from or seated on the valve seat surface.
