Abstract
An electromagnetically actuatable valve having a connection fitting serving as a core and on which a magnet coil is disposed, is produced with a non-bulky valve housing of ferromagnetic metal. This valve housing is simple to manufacture with a reduced external valve size. The valve is provided with a plastic sheathing that surrounds not only a connection fitting but also a magnet coil and at least in the region surrounding the magnet coil includes a ferromagnetic element that conducts magnetic field lines. These ferromagnetic elements are embodied by conducting elements and optionally by fillers having ferromagnetic properties, which at least partly surround the magnet coil in the circumferential direction. This embodiment of the valve is suitable for all types of electromagnetically actuatable components.
