A fuel injection valve apparatus that is provided to a cylinder of an internal combustion engine for injecting fuel supplied from a fuel supply system into the cylinder, the fuel injection valve apparatus comprising:

• an injection valve that includes:
• a fuel inlet that connects with the fuel supply system;
• an injector body that connects with the fuel inlet, the injector body having a pressure control chamber;
• a valve body that connects with the injector body, the valve body facing an interior of the cylinder, the valve body having a valve seat;
• a valve member that is surrounded by the valve body, the valve member being movable with respect to the valve set of the valve body, the valve member having a passage that communicates with the interior of the cylinder;
• and
• an actuator,
• wherein the valve member is seated on the valve seat by being applied with hydraulic pressure from the pressure control chamber at least when the actuator blocks the pressure control chamber from the passage,
• the valve member is lifted from the valve seat when the actuator communicates the pressure control chamber with the passage.
