A control valve for a fuel injection nozzle, having a control chamber, into which a fluid conduit discharges, and a valve element, which rests on a valve seat in the control chamber, so that the fluid conduit is closed. An armature plate, which is disposed in a damping chamber and has a pressure piece that cooperates with the valve element, and an armature coil. The armature, formed by the pressure piece and the armature plate is prevented from bouncing in response to a closing motion. For that purpose, an overflow conduit is provided between the control chamber and the damping chamber.
