Abstract:
1. A solenoid device comprising: a magnet armature; an armature counterpiece arranged at an end of the magnet armature, the magnet armature and the armature counterpiece being configured to move in relation to one another; an air gap defined between the magnet armature end and an armature counterpiece end, through which a magnetic series connection is established between the magnet armature and the armature counterpiece; and a disk configured to contact at least certain areas of both the magnet armature end and the armature counterpiece end at every position of the magnet armature relative to the armature counterpiece, the disk being composed of a magnetizable material and arranged in the air gap, wherein a magnetic shunt connection is established through at least certain areas of the disk at every position of the magnet armature relative to the armature counterpiece, and wherein the magnetic series connection has a lower reluctance than the shunt connection.
