An electromagnetically operable valve having an electromagnetic circuit which includes at least one solenoid coil, a core used as internal pole, and an armature, as well as a magnet housing at least partially surrounding the solenoid coil. The magnet housing is produced from a sheet-metal blank with the aid of rolling or bending. The magnet housing has a middle housing area that is adjoined in the axial direction on both sides by attachment areas which have a smaller outside diameter than the housing area. The valve is particularly suitable as a fuel injector for fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.

A fuel injector for fuel-injection systems of internal combustion engines includes two preassembled, independent assemblies. A functional part includes an electromagnetic circuit and a sealing valve, while a connection part is formed mainly by a hydraulic connection and an electrical connection. In the ready-mounted injector, electrical connecting elements and hydraulic connecting elements of both assemblies cooperate, thus ensuring a reliable electrical and hydraulic connection An extrusion coat in the interconnection region provides mechanical joining of both assemblies, great stability of the valve and sufficient imperviousness.
