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.
Claims7
An electromagnetically actuatable valve for fuel injection systems of internal combustion engines comprising a valve housing of ferromagnetic material, a valve seat, a valve closing element, a magnetic coil, and a flat armature arranged to engage said valve seat, said flat armature configured in the manner of a gear wheel having a plurality of radially protruding teeth spaced uniformly apart from one another, each of said teeth on said flat armature having stop lobes disposed a surface thereof remote rod said valve closing element, said stop lobes arranged to rest on a stop face upon excitation of said flat armature during excitation of said magnetic coil.
