Abstract:
Electromagnet valve, comprising:a valve housing, a valve closure member movably guided in said valve housing, a magnet armature fitted to the valve closure member and executing a stroke movement in the direction of a magnet core arranged in the valve housing in dependence on the electromagnetic excitation of a valve coil fitted on the valve housing, and a spring which, in the electromagnetically non-excited valve position, positions the magnet armature at a defined axial distance from the magnet core so that the magnet armature is separated from the magnet core by an interspace, wherein in addition to said spring, a spring element is interposed between the end surface of the magnet armature and the end surface of the magnet core, wherein the magnet core and the magnet armature include either convexly or concavely shaped end surfaces between which resides a plate-shaped spring element with a lever arm resiliently mounted on the end surface of said magnetic armature or the end surface of the magnet core.
