Abstract

A magnet core (14) which is penetrated by a tappet (35) guided in a bearing (38) is arranged in the interior (12) of an electromagnetic valve (10). A connection element (45) comprising plastic and having an integrally arranged valve seat (46) is injection molded onto the underside of the magnet core (14). As a result of the design and arrangement of the connection element (45) and bearing (38), the producibility of the electromagnetic valve (10) is simplified and its functional properties are improved.
