An annular gap for accommodating a plunger coil of a plunger coil arrangement is formed between a circumferential surface of the pole plate and the circumferential surface of the housing interior. The underside of the permanent magnet is bonded to the housing bottom surface. The pole plate is connected to the housing in a manner decoupled from the permanent magnet by a rigid fastening device and is positioned in such a manner that a lower side of the pole plate faces an upper side of the permanent magnet with a gap formed there between.
