Abstract
The invention is an actuating drive for deflecting an actuating element using a solid body actuator () when an electrical voltage or an alternating magnetic field is applied, to cause a change in length. A housing () encloses the solid body actuator to define an interspace () in a fluid-tight manner. Furthermore, the solid body actuator includes a hollow duct () having one end connected to a first hollow conduit () passing through the housing and the other end opening into the interspace (). The interspace is additionally connected in a fluid-tight manner to a second hollow conduit () passing through the housing.
