Abstract

An actuator device for producing a linear movement, has a hydraulic actuator which includes a first piston element for actuating the actuator and a second piston element for producing the linear movement. The piston elements are assigned respective fluidically coupled working chambers, the volumes of which can be changed by movement of the respective piston element. A piezoelectric actuator is provided for exerting a force on the first piston element.
