Abstract

An electromagnetic valve arrangement with a valve element having least one part disposed in a valve chamber defined by a valve insert in the region of a valve seat. An end facing away from the valve chamber of the valve element is operatively connected to an armature and end face of the armature facing toward the valve insert and/or an end face of the valve insert facing toward the end face of the armature is embodied with a surface profile such that a flow cross section, defined by the opposed end faces varies at least regionally in the radial direction and/or in the circumferential direction of the armature.
