Abstract

The SMA driven fluid control valve actuator includes a multiplicity of SMA wire sections for moving the movable element from a biased first position to a second position when heated. An electrical controller controls the heating of the SMA wire sections by regulating current therethrough, and may be governed by a position measurement to regulate current to the SMA drive element to position the movable element to a desired position. The valve actuator may also include a temperature controller governed by temperature signal provided by a temperature-sensing means in proximity to the SMA drive element to activate a cooling device for reducing the temperature surrounding the SMA drive element. The electrical controller may also be governed by both a position measurement and a temperature signal to regulate current to the SMA drive element and to control the cooling device to position the movable element to a desired position.
