Patent ID: 8613421

Claim:
A device for a flow control of a liquid or a gaseous medium, comprising: a valve element controlling at least one flow opening for the medium; an electromagnet actuating said valve element and having a magnetic circuit with at least one excitation coil and a solenoid armature coupled to said valve element and disposed between two diametrically opposed pole pieces located in the magnetic circuit such that said solenoid armature is swivelable about a swivel axis and extends beyond each of said pole pieces leaving two air gaps; at least one permanent magnet disposed such that its magnetic flux closes by said pole pieces, wherein said valve element has a closing head interacting with a valve seat that encloses said flow opening to close and open said flow opening; and an actuating lever on which said closing head is mounted and which is connected as a single piece to a sealing plate composed of an elastic material and forming a seal, and also connected by at least one coupling element to said solenoid armature, wherein said closing head and said sealing plate are interconnected as a single piece, wherein said at least one coupling element is a leaf spring having one spring end attached to said solenoid armature and another opposite spring end engaging on said actuating lever.
