| Zusammenfassung: | An enclosure (1) for enclosing piezoelectric elements of a piezoelectric actuator comprises a side wall that is shaped to define at least one strain compensation formation selected from a longitudinally-extensible part (5) at which the side wall can be extended or contracted parallel to a longitudinal axis of the enclosure (1); and an inwardly-deflectable part (9) at which the side wall can be deflected transversely to the longitudinal axis. |
