A device for injecting fuel into the combustion chambers of an internal combustion engine, with an injector enclosed by an injector housing, whose control chamber is acted on by a control volume, and with control valves for increasing/relieving the pressure in the nozzle chamber of the injector and in the control chamber of the injector. The control valves are disposed in parallel to one another. They are hydraulically coupled to one another without side effects by means of a coupling chamber, and are actuated by means of an actuator that can be switched into different stroke levels.
