ABSTRACT:
A piezoelectric motor actuated amplifier mechanism that utilizes a pair of saggital linkages having one relatively fixed saggital midpoint and joined at their end points to obtain a doubled amplification factor pull stroke output from one relatively movable saggital midpoint. Thermal compensators are employed between the piezoelectric actuator and the saggital linkages to stabilize the amplifier throughout a wide range of temperatures.
