Abstract
A coil assembly, e.g., for use a valve, is disclosed. The coil assembly includes a coil arrangement including at least one electrically energizable coil, a coil ring carrier receiving the coil arrangement, and a flux conducting device for conducting magnetic field lines of a magnetic field provided via the coil arrangement. The flux conducting device includes a one-piece ferromagnetic pole ring that includes a ring base plate and a plurality of pole ring outer teeth arranged on an outer edge of the ring base plate and angularly bent over on fold-over outer edge regions of the ring base plate. The flux conducting device further includes a one-piece ferromagnetic counter-pole ring that includes a counter-ring base plate and a plurality of counter-pole ring outer teeth arranged on a counter-outer edge of the counter-ring base plate and angularly bent over on counter-fold-over outer edge regions of the counter-ring base plate.
