ABSTRACT:
A fuel injection valve is provided in which a funnel-shaped fuel collecting depression (35) is provided between a valve seat (8) and an outlet hole (7) of a valve seat member (3), the depression (35) collecting fuel that has passed through the valve seat (8) and guiding it to the outlet hole (7), and a flat fuel diffusion chamber (36) for radially outwardly diffusing fuel that has passed through the outlet hole (7) and guiding it to a plurality of fuel injection holes (11) is provided between opposing faces of the valve seat member (3) and an injector plate (10), an inner peripheral face (7A) of the outlet hole (7) being formed along a curved face on the inner peripheral side of a virtual torus (T) so that the inner peripheral face (7A) is continuous with the base of the fuel collecting depression (35) and the roof of the fuel diffusion chamber (36). This prevents eddies from being generated when fuel is reversed at the outlet hole of the valve seat member, thus enabling pressure loss of the fuel to be reduced, reduction in the amount of fuel injected to be suppressed, atomization of injected fuel to be promoted, and a spray form to be stabilized.
