More Information
Summary:The actuator (2) comprises a piezoelectric actuator element (4), which is 18 connected to an adjusting element (12) for exerting an adjusting movement in the adjusting direction (14). For the transmission of a deflecting movement of the actuator element (4), a housing (6) is formed with a variable-shape displacer (8) enclosed therein. During operation, a deflecting movement of the actuator element (4) is transmitted to the displacer (8), so that the latter is deformed and, as a result of the deformation, performs a yielding movement. The housing (6) in this case forms a guide for the displacer (8), so that the yielding movement of the displacer (8) is oriented in the adjusting direction (14). The adjusting element (12) is also connected to the displacer (8), so that the yielding movement of the displacer (8) is transmitted to the adjusting element (12).
