The injection opening (3) is provided for influencing control chamber pressure on nozzle needle through an inlet throttle (8) and for filling highly pressurized fuel in open position of control valve through a discharge throttle (7). The pressure actuatable further valve (9) with a movable valve element (10) is formed upstream to inlet throttle for releasing and closing hydraulic connection of inlet throttle with a high-pressure region (11).
