Abstract
An electromagnetic actuator including an armature movable along a longitudinal axis in an armature chamber, a coil running around the longitudinal axis for producing a magnetic field for moving the armature, a control element motionally coupled to the armature, in particular for operating a valve element of a pressure-regulating valve, a pole disk for conducting a magnetic flux, and a cover bounding the armature chamber, the cover and the pole disk together forming a component in one piece.
