Actuator module having an enshrouded piezo actuator

摘要

Actuator module has a piezoactuator and casing of elastomer layer. The piezoactuator has a piezolement arranged between an actuator head and an actuator foot. The sleeve is made from a heat shrinkable tubing (26) which lies sealed within plant ranges on the actuator head (22) or the actuator foot (23) of the piezoactuator (21). A press ring (27) is located outside on the heat shrinkable tubing which presses the heat shrinkable tubing on the plant ranges.
