Abstract

The invention relates to an actuator device, having two working chambers which are coupled to one another in such a way that a volume increase in a first of the working chambers is associated with a volume decrease in the second working chamber, and vice versa. There is provided an output device which can be driven, and thus moved, by the respective volume increase in the respective working chamber. There is provided a pump device having a solid-state actuator and intended for conveying a fluid. There is provided a first flow path through which the fluid conveyed by means of the pump device can flow and via which, to bring about the volume increase in the first working chamber, the fluid conveyed by means of the pump device and flowing through the first flow path can be introduced into the first working chamber.
