Patent

CA 2752535

An actuator is disclosed which operates on the principle of the variable magnetic properties of materials with respect to temperature. As temperature is raised past Curie temperature, magnetic permeability of certain materials drops significantly to a value close to free space permeability. However, depending on the material selection, magnetic permeability may be significantly higher below Curie temperature. This principle is used to cause magnetic attractive force to move an actuator at one temperature, while permitting a return spring force to move the actuator at another temperature by changing the pathway traversed by most magnetic lines of flux from a magnetic source. The actuator may be employed to provide a temperature activated electrical switch or fluid valve. The temperature activated valves are suited to use in high temperature environments, such as SAGD wells.
