ABSTRACT:
An electrothermal actuator for converting electrical energy to rotational mechanical motion includes a housing, a flexible diaphragm disposed in the housing and defining a boiler chamber within the housing, a working fluid disposed within the boiler chamber and changing phase in response to heating, thereby displacing the diaphragm, a heater disposed within the boiler chamber for heating the working fluid in response to an electrical current flowing through the heater, and a rotatable shaft assembly partially disposed within the housing and including a rotating shaft extending outside the housing, rotating between a return position and a rotated position, and a driver for rotating the shaft from the return position toward a rotated position in response to heating of the working fluid, displacing the diaphragm.
