Patent ID: 7647943

Claim:
Solenoid comprising an armature movable in an armature room and a coil which can be flowed through by current, the coil generating, when flowed through by current, a magnetic field serving for movement of the armature so that the armature moves toward a direction of a control cone so that a front region of the armature immerses into the control cone, a width of a gap between the armature and the control cone changing with a diving distance of the armature into the control cone from a first gap width between a leading control edge of the armature and a leading control surface of the control cone, with a subsequent second increased gap width between an interior surface of the control cone and an exterior surface of the armature, and in a last phase of immersion of the armature into the control cone a third width of a gap between a trailing control surface of the armature and the leading control surface of the control cone decreases to approaching the first width gap.
