Abstract

The invention relates to an electromagnetic valve, with a valve tappet guided in a valve housing that exhibits a valve-closing element, with a valve-seat holding element facing the valve-closing element, which forms an independent subassembly together with the valve housing, as well as with an armature that activates the valve tappet and can be excited by means of a valve coil arranged on the valve housing. The armature is designed as a cold extrusion pressed part and the valve housing is designed as a deep drawn part or cold extrusion pressed part.
