Abstract: A drive apparatus for reversible movements of an actuator is provided with a drive element made from a shape memory alloy with one-way effect. The drive element acts upon a lever rotatable about an axle in opposition to the force of a resetting element, wherein the lever can be used as a coupling member for converting a deformation of the drive element into a movement of the actuator. The drive element is a winding with a plurality of turns of a wire, wherein the turns are fixed and arranged mechanically parallel between an anchor point and the lever so that the lever is rotatable about the axle by means of a deformation of a turn, and the tractive force acting upon the lever by means of the drive element results from the individual forces of the turns of the winding acting mechanically parallel upon the lever. The diameter of the wire is advantageously approximately equal to the standardised diameter of the crystalline grain of the shape memory alloy in the austenitic state.
