Abstract

The invention provides an actuator device, which has: an output element, which is acted on by a fluid and as a result is movable into a holding position; two solid-state actuators, which are able to be activated alternately; a coupling element common to the solid-state actuators; a discharge duct, via which the fluid is able to be discharged from the output element; and at least one valve element, which is adjustable between a blocking closed state and an open state, in which the valve element allows the fluid to be discharged from the output element via the discharge duct and allows the output element to move from the holding position into at least one yielding position, wherein the valve element is actuable, via the coupling element of the respective solid-state actuator, by the respective activation of the solid-state actuator and is able to be moved into the closed state.
