Abstract
A method and a device for transmitting an elastic deflection of a piezoelectric element to an actuator by using a direct voltage source, generated from a supply voltage, for charging or discharging the piezoelectric element. An actuating motion of the actuator is modified as a function of the control voltage of the piezoelectric element, the voltage gradient being simultaneously adjusted to the control voltage.
