SHAPE MEMORY ALLOY VALVE AND METHOD FOR FABRICATION THEREOF

SHAPE MEMORY ALLOY VALVE AND METHOD FOR FABRICATION THEREOF

A shape memory alloy (SMA) valve including an SMA activator component having a shape memory effect to open or close the valve. The SMA valve may be formed from a monolithic sheet of SMA or a wire of SMA. The SMA valve may operate via choking, torsion or lateral movement in one or more dimensions. Th...

description A shape memory alloy (SMA) valve including an SMA activator component having a shape memory effect to open or close the valve. The SMA valve may be formed from a monolithic sheet of SMA or a wire of SMA. The SMA valve may operate via choking, torsion or lateral movement in one or more dimensions. The SMA valve may include a stage or ball seal and the SMA actuator component may be provided to the stage or ball seal and configured to move the stage or ball seal to seal or open a flow of gas or liquid when the shape memory effect is activated. The SMA valve may include heat sinks to help adjust the temperature of the activator components and/or may include a biasing component to bias the valve in a particular direction.
