Abstract
Official abstract text for this publication.
The invention is an actuating drive for deflecting an actuating element using a solid body actuator ( 2 ) when an electrical voltage or an alternating magnetic field is applied, to cause a change in length. A housing ( 1 ) encloses the solid body actuator to define an interspace ( 13 ) in a fluid-tight manner. Furthermore, the solid body actuator includes a hollow duct ( 6 ) having one end connected to a first hollow conduit ( 20 ) passing through the housing and the other end opening into the interspace ( 13 ). The interspace is additionally connected in a fluid-tight manner to a second hollow conduit ( 21 ) passing through the housing.
First claim
Opening claim text (preview).
The invention claimed is: 1. An actuating drive for uniaxial bi-directional deflection of an actuating element comprising: a solid body actuator with an end located at an end of the solid body actuator having a first frontal face in a housing, the solid body actuator changing in length in a longitudinal direction along a longitudinal axis of an actuating element in response to an electrical voltage applied to the solid body actuator or a magnetic field acting on the solid body act…
