Abstract

An electromagnetic actuating unit of a hydraulic control valve which has an armature disposed inside an armature chamber in an axially displaceable manner, and a pole core disposed in a recess. The pole core limits the armature chamber in a direction of movement of the armature. The geometry of the armature serves to adjust the characteristic line of the electromagnetic actuating unit.
