Abstract

An electromagnetically operable valve having an electromagnetic circuit which includes at least one solenoid coil (1), a core used as internal pole, and an armature, as well as a magnet housing (60) at least partially surrounding the solenoid coil (1). The magnet housing (60) is produced from a sheet-metal blank with the aid of rolling or bending. The magnet housing (60) has a middle housing area (630) that is adjoined in the axial direction on both sides by attachment areas (640, 650) which have a smaller outside diameter than the housing area (630).The valve is particularly suitable as a fuel injector for fuel-injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
