Abstract

Die Erfindung betrifft einen piezoelektrischen Aktor (1, 1') für unströmende Medien, mit einem zwischen zwei Endkappen (3, 3') angeordneten Piezoelement (2). Das Piezoelement (2) ist von einer mit den Endkappen (3, 3') verbundenen, ringförmigen Ummantelung (5) umgeben. Die Ummantelung (5) besteht zumindest abschnittsweise aus einem Verbundwerkstoff (11, 11') mit mindestens zwei Schichten (12, 13) , wobei mindestens eine Schicht (12) aus einem metallischen Werkstoff und mindestens eine Schicht (13) aus einem Polymer besteht.
