Abstract: An electromagnetic switching device (10) and a method for producing the electromagnetic switching device (10) are disclosed. To this end, a magnetic armature (13) and a pressure pin (19) which is movable in a bearing (21) along an axis (A) are provided. A bearing sleeve (11) accommodates at least the bearing (21) and the magnetic armature (13). An electromagnetic casing (12) and the bearing sleeve (11) are together made of a single material in the form of a one-piece component (100).

Abstract: A valve housing for a control valve of a camshaft adjuster, including a housing flange for fastening to a control unit as well as an essentially cylindrical housing component for accommodating a control piston. It is provided that the housing component is rotatably fixedly attached to the housing flange by a form-locked connection. A valve housing of this type is cost effective to manufacture and has a low weight, while ensuring operational reliability. The invention furthermore relates to a method for manufacturing an aforementioned valve housing.

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.
