The electromagnet, at least comprising a magnet coil wound onto a coil core, a housing, a pole core, an armature, an armature rod and a yoke, should have a very low hysteresis of the force with a variable stroke at low manufacturing costs. The coil core is manufactured by jointly overmolding or overcasting the yoke, the pole core and the core flange with a plastic mass, wherein the axial intermediate space between the yoke and the pole core (4) is also filled with the plastic mass. Electromagnets of the described type are used for actuating fluid valves or couplings, preferentially in motor vehicles or in mobile working machines.

An electromagnetic actuating device includes a pole tube that is substantially cylindrical overall, an armature situated radially inside the pole tube, and an electromagnetic coil situated radially outside the pole tube, the pole tube having a first axial end and a second axial end. The pole tube is configured as a sleeve that is stamped and is brought into its shape by reshaping, the sleeve having, close to its first axial end, openings that extend in the circumferential direction.

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 the armature unit (7) from the spring member (14) about the displacement axis (V) at the armature unit (7) and/or for decoupling a rotational movement of the spring member (14) about the displacement axis (V) from the abutment component (16).
