Abstract: An electromagnetic fuel valve has a valve chamber, a valve element and a valve seat assigned to the valve element. The valve chamber is delimited by an electromagnetic drive which moves the valve element relative to the valve seat. The drive includes a receiving housing for a coil carrier with an electrical coil. A magnet core is inserted into the coil carrier and has an end section facing the valve element. At an open sealing end facing toward the valve chamber, a sealing element is arranged between the end section of the magnet core and the receiving housing. To achieve good sealing, that end section of the magnet core situated in the sealing element expands the sealing element and compresses the material thereof radially against the edge of the sealing end of the receiving housing to seal the valve chamber to the interior space of the receiving housing.
