Abstract
The present invention relates to an electromagnet valve including a valve housing in which a valve closure member is movably guided, 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. In addition to spring, a spring element that has a non-linear, preferably progressive characteristic curve acts on the magnet armature, the said spring element counteracting the magnet force.
