Abstract
An electromagnetic actuator device has at least one stationary spool unit (4), which can be energized, and at least one armature unit (7), movable along a displacement axis (V) and with respect to the spool unit (4) in reaction to the spool unit (4) being energized. The armature unit (7) 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 (7), and can be rotated about the displacement axis (V). A spring member (14) supported against an abutment component (16) is preferably disposed in a torque-proof manner and allocated to the armature unit (7) in such a manner that the spring member (14) applies a spring force to the armature unit (7) during a displacing movement in the output drive direction while simultaneously at least partially relaxing and applying a spring force to the armature unit (7) when in the actuating position. It is intended that the spring member is supported against the abutment component (16) by a rotation decoupling member (15) for decoupling a rotational movement of …
