Abstract

In valves having flat armatures, in order to attain the shortest possible switching times, the goal is to to reduce the mass of the armature and the surface area of the stops. A particularly advantageous design is obtained by embodying the flat armature in the manner of a gear wheel and providing at least three radially extending teeth, spaced uniformly apart from one another, on which the stop lobes that cooperate with a stop integral with the housing upon actuation of the valve by excitation of the magnetic coil are formed. A flat armature embodied in this way can be used in any correspondingly embodied valve.
