Abstract

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.
