Actuator device and method for operating such an actuator device

A method for operating an actuator device, in which the actuator device indicates:

• a minimum of two working chambers which are coupled to one another in such a way that an increase in volume of a first of the working chambers is accompanied by a reduction in volume of the second working chamber and vice versa,
• a drive unit device, which is driven by the respective increase in volume of the respective working chamber and moved thereby,
• a pump device indicating a minimum of one solid actuator, by means of which a fluid is conveyed,
• a first flow path through which the fluid conveyed by the pump device can flow, via which the fluid conveyed by the pump device and flowing through the first flow path is introduced into the first working chamber in order to effect the increase in volume of the first working chamber,
• a second flow path through which the fluid conveyed by the pump device can flow, via which the fluid conveyed by the pump device and flowing through the second flow path is introduced into the second working chamber in order to effect the increase in volume of the second working chamber,
• a first discharge path associated with the first working chamber, via which the fluid is discharged from the first working chamber to reduce the volume of the first working chamber,
• a second discharge path associated with the second working chamber, via which the fluid is discharged from the second working chamber to reduce the volume of the second working chamber,
• a first valve element arranged in the first discharge path, which is moved between a first closed position closing the first discharge path and a minimum of one first open position releasing the first discharge path,
• a second valve element arranged in the second discharge path, which is moved between a second closed position closing the second discharge path and a minimum of one second open position releasing the second discharge path,
• a first actuating path, which is fluidically connected to the first flow path at a first branching point arranged downstream of the pump device and upstream of the first working chamber, at which a portion of the fluid which is conveyed by means of the pump device and flowing through the first flow path is subsequently branched off from the first flow path and introduced into the first actuating path, via which the second valve element is actuated by means of the fluid which is introduced into the first actuating path and flowing through the first actuating path and is thereby moved from the second closed position into the second open position, and
• a second actuating path, which is fluidically connected to the second flow path at a second branch point arranged downstream of the pump device and upstream of the second working chamber, at which a portion of the fluid which is conveyed by means of the pump device and flowing through the second flow path is subsequently branched off from the second flow path and introduced into the second actuating path, via which the first valve element is actuated by means of the fluid introduced into the second actuating path and flowing through the second actuating path and is thereby moved from the first closed position into the first open position.
