Abstract
In an electromagnet with sleeve-shaped magnet housing with integrated valve body, in particular for the actuating of valves, the pole core is developed as a separate part and is surrounded by the sleeve-shaped magnet housing. The magnet housing has inward-directed corrugations distributed uniformly over its circumference which serve as axial support for the pole core in the direction of the electric windings.
