An electromagnetic positioning system (), including a valve train adjustment system for combustion engines, including a bistable electromagnetic positioning device () having a positioning element () for interacting with a positioning partner, the positioning element being adjustable between a retracted position (E) and an extended position (A) along an axis of adjustment (A) and having permanent magnet means () at least in sections.

Electromagnetic positioning system and operating method

An electromagnetic actuator device has at least one stationary spool unit (), which can be energized, and at least one armature unit (), movable along a displacement axis (V) and with respect to the spool unit () in reaction to the spool unit () being energized. The armature unit () can be displaced between a parked position and an actuating position in an output drive direction along the displacement axis (V) in order to interact with an actuating element, which can be a camshaft disposed on the output side of the armature unit (), and can be rotated about the displacement axis (V). A spring member () supported against an abutment component () is preferably disposed in a torque-proof manner and allocated to the armature unit () in such a manner that the spring member () applies a spring force to the armature unit () during a displacing movement in the output drive direction while simultaneously at least partially relaxing and applying a spring force to the armature unit () when in the actuating position. It is intended that the spring member is supported against the abutment component () by a rotation decoupling member () for decoupling a rotational movement of the armature unit () from the spring member () about the displacement axis (V) at the armature unit () and/or for decoupling a rotational movement of the spring member () about the displacement axis (V) from the abutment component ().
