Solenoid valve for controlling an electrically controlled fuel ignition valve

A magnet valve (30) for controlling an injection valve of a fuel injection device comprising a valve needle (6) whose opening and closing is controlled by the magnet valve, said magnet valve has an electromagnet (29), an armature including first and second parts (28, 27) in which said second part is embodied as an armature bolt, a valve member (25) that is moved with the armature and is urged in a closing direction against a valve seat (24), said first armature part (28) under the influence of an inertial mass is slidingly displaceable relative to said second armature part (27) in a closing direction of the valve member (25) counter to a force of a restoring spring (35), the first armature part includes a hydraulic dampening device which includes a first part and a second part, said first part of said hydraulic dampening device cooperates with the second part of the hydraulic damping device, said second part of said hydraulic damping device is fixed in a stationary way at the latest in the closing position of the valve member, so that revibration of the first armature part (28) in a dynamic displacement counter to the stationarily fixed part reduces a volume of a damping chamber (50, 50') that is enclosed between the first part of said hydraulic damping device and the second part of the hydraulic damping device, and said damping chamber is relieved via a leakage gap formed between the first part of the hydraulic damping device and the second part of the hydraulic damping device.
