Piezoelectric actuator with a sheathing composed of a composite material

摘要

A piezoelectric actuator for flowing-around media, with a piezo element arranged between two end caps. The piezo element is surrounded by a ring-shaped sheathing connected to the end caps. The sheathing consists, at least in portions, of a composite material with at least two layers, at least one layer consisting of a metallic material and at least one layer consisting of a polymer.
