ABSTRACT:
A supplementary mass is arranged in an electromagnet system between armature and reset spring in such a way that, after reaching an end position, the armature is relieved of the spring force; due to the relief, a high excess of magnetic force is available for braking the subsequent bounce movement; the mass and force conditions of the magnet system are matched so that the subsequent collision of armature and supplementary mass occurs counter-directionally and the remaining kinetic energy of the armature is used up to a large extent by the counter-directional collision; the small bounce movement permits the use of spring systems with very high reset forces when the armature is pulled-in whereby the movement times of the armature are greatly shortened; and specific springs and spring arrangements for producing suitable reset spring force characteristics are described.
