Abstract
The invention relates to an actuator () which can be moved from an initial position into a working position having at least one actuator element () whose dimensions can changed by an electrical signal, Appropriately, at least two restoring means () acting on the actuator element () are provided for movement into the working position. With the at least two restoring means, a total restoring means characteristic curve, which is composed of portions of the individual, preferably preloaded restoring means as well as a portion of a variable stiffness of the actuator element, can be advantageously tailored.
