A fuel injection device for an internal combustion engine includes a first valve element with a pressure face acting in the opening direction. An actuating device acts in the closing direction. A second valve element has a hydraulic control face, acting in the closing direction, which defines a hydraulic control chamber. A corresponding actuating device acts in the opening direction. A high-pressure connection is provided. The fuel injection device includes an additional valve device, which in a first terminal position connects the pressure chamber only with the low-pressure connection and the control chamber only with the high-pressure connection. In a second terminal position, the additional valve device connects the pressure chamber only with the high-pressure connection and essentially disconnects the control chamber from the high-pressure connection. In an intermediate position, the pressure chamber communicates only with the high-pressure connection, and the control chamber communicates simultaneously with both the high-pressure connection and the low-pressure connection.
