ACTUATING DRIVE AND METHOD FOR COOLING A SOLID BODY ACTUATOR HOUSED IN AN ACTUATING DRIVE WITH AN ACTUATING ELEMENT |
摘要 |
The invention ris an actuating drive for deflecting an actuating element by a solid body actuator (2) which, when an electrical voltage or an alternating magnetic field is applied, experiences a length change. 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. The interspace is additionally connected in a fluid-tight manner to a second hollow conduit (21) passing through the housing. |
