  • Patent number: 4177440
    Abstract: The invention relates to a moving-armature electro-magnetic device such as a plunger core electromagnet wherein a ring of a non-magnetic material with an appropriate anti-friction coefficient is placed between the armature and the seat which cooperates with said armature. Said ring permits to reduce to a minimum both the frictional forces and the remanence forces between said armature and said seat.
