Abstract:
1. A device for injecting fuel, comprising: a valve body; an outwardly opening valve needle, which is disposed in the valve body in a pressure chamber filled with fuel, to which pressurized fuel is supplied; a restoring element, which returns the valve needle to an original position; an electromagnetic actuator, which is disposed in an actuator chamber for actuating the valve needle; and a diaphragm, which is disposed in the actuator chamber and subdivides the actuator chamber into a first, fuel-filled region and a second, fuel-free region in fluid-tight manner, and which subdivides the valve needle into an injection-side portion and an actuator-side portion; wherein the injection-side portion of the valve needle includes a pressure-compensation plunger, which separates the pressure chamber from the first, fuel-filled region of the actuator chamber, and wherein the actuator is disposed in the second, fuel-free region, wherein the pressure-compensation plunger is distinct from the valve needle.
