ABSTRACT:
An electromagnet, for valves, comprises thin-walled axially symmetrical parts and is adapted to different uses by special air gap arrangements and armature suspensions; the electromagnet generates high magnet forces at low armature mass and is employable, in particular, for actuation of fuel injection valves for internal combustion engines and in general hydraulics; the electromagnet possesses a high mechanical stability and eddy current depletion combined with simple armature suspension and low cost of manufacture.
