摘要:
A thermally driven piston assembly comprises a material that undergoes a dimensional change when subjected to a temperature change in the temperature range of interest. The dimensional change imparts movement which effects an end result such as actuation, shock absorption, clutch action, braking, or mechanical power. The assembly can further comprise position sensing means for sensing movement of the component of interest, and passive and/or active heating and/or cooling means for effecting the temperature change.
