Abstract (en)
[origin: DE19955079A1] The electromagnetic drive has a reciprocating magnetic armature for operation of a valve element (6) and at least one cooperating electromagnet (7,8), with the depth to width ratio of both the armature and the electromagnet being greater than 1.5, e.g. greater than 3. A pair of opposing spring forces (16) hold the magnetic armature in an intermediate position between its end positions when neither electromagnet is supplied with current.
