摘要： 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.

摘要： A solenoid valve for a fuel system has an electric coil and an armature disposed in a housing. A preassembled valve unit with valve seat, valve member, valve spring, and armature plate connected captively to each other is provided. In the valve unit, the valve seat is loosely secured between valve member and armature plate. The valve unit is inserted and secured in an open housing end and the valve spring contacts an inner shoulder of the housing. Armature plate and armature form a magnetic circuit. The valve member is supported on the armature plate and switched to open and close an outlet of the valve seat. By suppling current, a magnetic field is generated in the armature and attracts the armature plate into an operative valve position. The valve spring returns the armature plate into a rest position when the coil is currentless.
