ABSTRACT:
A piezoelectric actuator module having at least one piezoelectric component, one actuator foot, and one actuator head is surrounded by an axially extending bush. For sealing the piezoelectric actuator module in the axial direction, the actuator foot is adjoined by a diaphragm, which extends essentially in the radial direction, is joined to the bush, and has a cross section with various radii of curvature.
