  • This eccentricity is due on the one hand by a game of magnet armature 09 and the pressure pin 11 in the storage.
  • the eccentricity is a consequence of a deviation from the coaxiality between an armature bearing 13 and a pole core bearing 14.

  • the armature and the pressure pin execute the axial displacement movement together.
  • the armature is in the magnetic field of the coil, whereby a magnetic force acts on it, which causes the displacement movement.
