Abstract
A valve for preventing the flow of fluid from an outlet when the temperature of the fluid is above a predetermined threshold. The valve including: a body having at least one opening for allowing the fluid to pass through the outlet when the temperature of the fluid is below the predetermined threshold; and a shape memory actuator for substantially closing the at least one opening when the temperature of the fluid is above the predetermined threshold to prevent the fluid from passing through the outlet.
Claims11
A valve for preventing the flow of fluid when the temperature of the fluid is above a predetermined threshold, the valve comprising:
- a body having at least one opening for allowing the fluid to pass when the temperature of the fluid is below the predetermined threshold;
- and
- a shape memory actuator for substantially closing the at least one opening when the temperature of the fluid is above the predetermined threshold to prevent the fluid from passing;
- wherein the valve is configured such that a flow of the fluid through the body acts to close the shape memory actuator against the at least one opening.
