Piezohydraulic actuator

A piezohydraulic actuator comprising:

• a piezo actuator;
• a drive having a drive chamber supplied with a hydraulic fluid and a drive piston element delimiting the drive chamber and driven by the piezo actuator;
• a first output having a first output chamber and a first output piston element;
• wherein at least part of the hydraulic fluid is conveyed out of the drive chamber by movement of the drive piston element and into the first output chamber;
• wherein the first output piston element delimits the first output and includes a hydraulically active first output face loaded with hydraulic fluid introduced into the first output chamber;
• a second output having a second output chamber and a second output piston element;
• wherein at least part of the hydraulic fluid is conveyed out of the drive chamber and into the second output chamber;
• wherein the second output piston element delimits the second output chamber and a hydraulically active second output face which is larger or smaller than the first output face and can be loaded with hydraulic fluid introduced into the second output chamber and driven by loading the second output face with the hydraulic fluid introduced into the second output chamber;
• and
• a coupling device mechanically coupling the first output piston element to the second output piston element.
