ABSTRACT:
A solenoid valve comprises a valve chamber between a base body and a magnet head and in the valve chamber a magnet armature functioning as a valve member is located. The actuation of the magnet armature takes place by activation of an electromagnet means, which possesses a magnet core arrangement with a plurality of pole faces facing the magnet armature. In order to reduce the impact of the magnet armature a damping plate arrangement is located between the magnet armature and the pole faces, such plate arrangement being in the form of a material which is not ferromagnetic.
