Abstract:
1. A device, comprising: an actuator having an actuating axis; at least one shape memory element which, by the application of a controllable magnetic field, executes a control stroke travel that operates the actuator, wherein the at least one shape memory element has a planar wall structure extending parallel to the actuating axis; and a coil that excites the magnetic field, the coil being situated in a magnet housing, wherein the magnet housing has a first end face and a second end face extending perpendicular to the actuating axis, and wherein at least one of (i) the first end face has a first through opening, and (ii) the second end face has a second through opening, and wherein the coil is positioned between the first and second end faces and radially wound around the actuating axis, and when viewed along the actuating axis, the coil radially surrounds at least one of the first through opening and the second through opening; wherein the at least one shape memory element is at least partially situated in the at least one of the first and second through openings.
