A fuel injection apparatus for internal combustion engines is proposed, which has a high-pressure fuel source from which fuel is supplied to an injection opening by means of a control valve unit. The control valve unit has a valve body, a valve member disposed in an axially mobile manner inside this valve body, and an actuator unit that actuates the valve member. A first high-pressure line connected to the high-pressure fuel source feeds into a first valve chamber of the control valve unit. In addition, a first valve seat is provided on an outer diameter of the valve body between the first valve chamber and a second valve chamber that communicates with the injection opening by means of a second high-pressure line. A second valve seat is formed on an inner diameter of the valve member and is engaged by a closing device.
