Magnet armature construction having a ferromagnetic body and an elastomer sealing element. The ferromagnetic body is preferably a cylindrical body, having a lateral surface and two head ends. At least one of the head ends is provided with at least one seat having a bottom surface and a circumferential wall. This seat is shaped in such a manner that a positively locking anchoring with the sealing element is obtained by one or more positively locking geometric formations being provided in the circumferential wall of the seat. The elastomer sealing element is injection-moulded into this seat. The positively locking anchoring is also effected by at least one cavity being provided in the ferromagnetic body, through the bottom of the seat. The circumferential wall of this cavity is provided with at least one positively locking geometric formation. A part of the elastomer sealing element is injection-moulded into this cavity. <IMAGE> |
