Abstract: A mechanism for coupling motion of a piezoelectric actuator in axisymmetric devices like modulating proportional valves uses actuator extension motion to cause translation away from a mechanism mounting plane and thereby enables lifting open of a valve element instead of the usual pushing closed of the valve element.

The mechanism surrounds a piezoelectric stack actuator by contacting opposite ends of the piezoelectric stack, whereby extension motion lengthening the actuator causes a lifting portion of the mechanism to translate toward the bulk of the actuator while the proximally adjacent mounting portion of the mechanism remains at a fixed location.
