Abstract
An adjusting device with a piezo drive is provided with two piezo translators which are brought into functional connection with a driven element by means of a spring element. A transmission of motion occurs corresponding to the change in length of the piezo translators, while resetting of the piezo translators occurs by removing the functional connection through their associated control links. Because of the continuous biasing of the spring element, a secure engagement of the driven element is guaranteed. As a result, the high precision requirements on the control links and their positioning displacements, which would otherwise be necessary for engagement, can be displaced with.
