Abstract

The invention relates to an electromagnetic valve, on the magnet armature of which a circumferential annular groove is arranged and in the valve housing of which an axially movable throttle disk is arranged, the throttle disk being fundamentally positioned at the height of the annular groove. The throttle disk throttles the pressure-medium flow along the magnet armature dependent on the actuation of the magnet armature in order to damp the armature impact noise.
