applied in the working air gap. In a further known electromagnet with anti-adhesive washer the latter as a prestressed plastic ring in a groove of the conical armature arranged in the transition area of its cone and cylinder part.

Disadvantages of the aforementioned measures must once the time-consuming and complex attachment of an anti-stick clamp by means of adhesive or, if necessary, by means of shaft locking and, on the other hand, the attachment of an anti-adhesive disc at the anchor, since in the latter case the manufacturing inaccuracies are difficult to avoid \ uid the lain and forwards movement of the anchor easily an additional rieioung of the anti-adhesive disk differently Anchor guide is generated. This is especially true for Anti-adhesive disks loosely inserted into the working air gap. The innovation is based on the task mentioned above To avoid disadvantages and to create an electromagnet with a partially novel shape, the one time-saving, safe and additional friction eliminating Attachment of a simply designed, easy-to-manufacture anti-adhesive disk is permitted.

This task is performed with electromagnets with piston armature and Anti-adhesive washer in which the anchor end forming the working air gap is a hollow inner cone and the fixed end

Opposite pole is designed as a complementary outer cone, according to the invention solved in that the fixed opposite pole from a short, cylindrical part and a paragraph leading to a smaller diameter with a adjoining outer cone, which at the shoulder between the cylindrical part \ xnd the outer cone with a annular groove is provided and a non-magnetic, tough elastic anti-adhesive disc on the heel carries the is crushed with its center hole in the groove »

In order to achieve a perfect fixation of the anti-adhesive disk, the innovation - "always provides that the center hole the anti-adhesive disk is smaller than the largest diameter of the outer cone at the opposite pole, and that the anti-adhesive disk is punched from a tough elastic plastic film.

An embodiment of the innovation is shown in the drawing and is described in more detail below.

The one from a short, cylindrical part 1 a and one leading to a smaller diameter Paragraph 2, adjoining outer cone 1b existing opposite pole 1 is at the end of the armature bushing 3 within this arranged and riveted to the magnet yoke 4. Between the cylindrical part 1a and the outer cone Ib is in

Extension of paragraph 2 to the central axis of a mrfc 5 screwed in ο One from a non-magnetic, viscoplastic one Material such as polyamide consisting of one Foil punched anti-adhesive disk 6 is with its central hole 6a, which has a smaller diameter than has the largest diameter of the outer cone 1b, after slipping over this outer cone into the Groove 5 blown in. The width of the anger 5 is slightly larger than the strength of the completely flat on the heel 2 anti-adhesive discs 6 on top »

Since the axial length of the outer cone 1b at the opposite pole 1 is less than that of the hollow inner cone 8b in the armature "is dimensioned, the impact energy of the in the Ankerlau-i-socket 3 moved within the coil 7 in the direction of the arrow PP ' Armature 8 thus caught on the annular anchor face 8a of the Antiklebscheioe 6 and the Impact noises are muffled accordingly, where Dei these ring-shaped Ankersti-r-nflache 8a the paragraph 2 at the opposite pole 1 do not touch them and thus no remanence-related adhesive effect can occur.
