to lead from a non-magnetic material, however this has the disadvantage that the course of the Field lines are sensitively disturbed by this guide sleeve ^ ird »

The! Innovation is now based on the task of creating a To create leadership of the piston-like armature, at which basically avoids the disadvantages listed remain and also other parts of the gate are more effective Kind to be achieved.

This object is achieved according to the Heuerung in that serving Gleitlagerbuohs en disposed in the bore of the piston-shaped Kagnetgehäuses storage Ankara are.

In two dimensions, only two such plain bearing bushings are seen and are arranged at the two seams of the bore. Their width or height is then preferably selected to be greater than the maximum stroke of the armature.

Furthermore, it has proven to be advantageous to choose the inner diameter of the bearing bushes only a few tenths of a millimeter smaller than the clear width && r bore of the magnet body. In order to keep the occurring magnetic losses as low as possible, you can see the clear? '© ite of the mentioned: Bore advantageously no more than 2/10 mm larger than the outer diameter of the piston-shaped armature. Ks can be achieved in that the annular air gap between the bore and the outer surface of the armature located between the plain bearing bushes is no more than 1/10 mm.

The plain bearing bushes can be made of plain bearing

be made of metal. " but also made of plastic
The strength of these plain bearing bushes needs * especially * who they are made of plastic, for example;!? 2/10 Bim ', where such thin sliding bearing sleeves are advantageously sprayed on. .
