Abstract

A piezo actuator for carrying out an actuating movement is disclosed, with a piezo bending transducer made of a carrier layer which is at least partially covered on one or two sides with a piezo lamella, with a movable end and with a housing, with a reference stop connected to the housing for determining a reference position for the actuating movement, with a first bearing region which comprises regions of the piezo actuator and the housing and which allows for twists ϕ1 of the piezo bending transducer, with a second bearing region having a surface on the side of the bending transducer and a surface on the side of the housing, and an intermediate layer between the surfaces, which connects them and which can be liquefied, and with a pressure element for generating a bias torque on the piezo bending transducer around the first bearing region against the reference stop.
