ABSTRACT:
An actuator assembly comprises a first diaphragm (422) and a second diaphragm (424) connected to the first diaphragm for forming a chamber (426) between the first diaphragm and the second diaphragm. An actuator shaft (427) is connected to first diaphragm (422) and is oriented to extend through the chamber (426) and to extend through an aperture formed in the second diaphragm (424). The second diaphragm (424) can be connected to an actuator body (450) wherein the actuator shaft (427) performs an actuation operation. Alternatively, one or more actuator amplification assemblies (400(B)) can be interposed between the second diaphragm and the actuator body.
