In a control device for a high pressure injection nozzle including a housing, an actuating magnet structure disposed in the housing and including a magnetic coil, an armature movable relative to the coil, and a valve actuating bolt engaged by the armature and being spring-biased to a seated position in which the injection nozzle is closed, the armature is movably mounted on the armature bolt and a mass body is resiliently supported adjacent the armature so that, upon de-energization of the magnet coil when the armature and the spring biased bolt are released and the bolt reaches the seated position, the armature is free to continue to move for engagement with the mass body to which the mass impulse forces of the armature are transferred, whereby the mass forces generated by the bolt when being seated are reduced and the movement of the armature is damped.
