Abstract: An actuator device includes at least one actuator element, which consists at least partially of a magnetically shape-shiftable material and which is configured at least for the purpose of causing a movement of at least one actuation element in at least one direction of movement by means of a contraction, and having a magnetic contraction unit, which is configured for the purpose of supplying a magnetic field acting upon the actuator element in order to generate a contraction of the actuator element. In the region of the actuator element, field lines of the magnetic field are aligned at least substantially parallel to the direction of movement.

Abstract: An electromagnetic positioning device (1), having a stationary spool unit (9), having a moveably guided anchor (2), which forms a positioning section (14) and which can be axially displaced along a displacement axis (V) in response to supplying the spool unit (9) with current, as well as having a one-part cup-shaped yoke-core element (3), which receives the anchor (2) and which includes a core section (5) as well as a yoke section (6) and which has a yoke-core bottom (4) extending perpendicular to the displacement axis (V) and a yoke-core sheath extending perpendicular to the yoke-core bottom (4) along the displacement axis (V), a longitudinally cut transition area (8) reduced in thickness and arranged between the core section (5) and the yoke section (6) being realized in the yoke-core sheath. It is intended that a guide pin (17) for the anchor (2) is fixed, preferably pressed in, in a, preferably centric, guide pin recess (18) in the yoke-core bottom (4) and protrudes axially into a, preferably centric, guide opening (13) of the anchor (2) and can be displaced relative to the anchor (2) during its displacement movement.

Abstract: A camshaft adjustment device comprising an electromagnetic actuator (3) having an armature that can be adjusted axially along an adjustment axis (5) for actuating a hydraulic valve for camshaft adjustment, and fastening means for fastening the actuator (3) on an engine element (3), wherein the fastening means comprise spring means (12), which tension the actuator (3) against the engine element (2) in a securing position (13), wherein the fastening means have positive-fitting means (8) as an anti-twist device for preventing a twisting movement of the actuator (3) in an installation position (7) relatively to the engine element (2), which are constructed and arranged in such a manner that the actuator (3) can be moved to the engine element (2) by means of a pure translational installation movement and wherein the spring means (12) in the securing position (13) bar a de-installation path for a purely translational de-installation movement of the actuator (3) opposite to the installation movement in such a manner that the same cannot be de-installed oppositely to the purely translational installation direction.
