| 摘要 |
The invention relates to an electromagnetic actuator device having at least one stationary, energisable coil unit (4) and at least one armature unit (7) movably guided along a displacement axis (V), which can be moved relative to the coil unit (4) as a reaction to the energisation of the coil unit (4), wherein, in order to interact with an actuating partner that can be provided on the drive side of the armature unit (7), in particular a camshaft, the armature unit (7) can be displaced in an output drive direction along the displacement axis (V) between a parked position and an actuating position and also rotated about the displacement axis (V), and wherein the armature unit (7) is assigned spring means (14) supporting a preferably rotationally fixedly arranged abutment component (15), in such a way that said spring means apply a spring force to the armature unit (7) in the output drive direction during the displacement movement, at least partly relax in the process and preferably also still apply the spring force to the armature unit (7) in the actuating position. According to the invention, the spring means (14) is supported on the armature unit (7) via rotation-decoupling means (15) to decouple a rotational movement of the armature unit (7) from the spring means (14) about the displacement axis (V) and/or on the abutment unit (16) to decouple a rotational movement of the spring means (14) about the displacement axis (V) from the abutment component (16). |
