Abstract: A seal assembly that includes a first mating component, a second mating component, and a gasket having a predetermined shape that is positioned between the first and second mating components and subjected to compression load. The gasket is constructed out of a memory material, such as a nickel titanium alloy. Upon application of heat from a heat source, gasket is urged to the original predetermined shape from the compressed configuration, thereby applying a desired force against the first and second mating components.

Abstract: The present invention discloses a shaft seal assembly. A seal retainer member is created from a shape memory alloy and used in combination with a resilient body to seal a shaft. Any deformities in the retaining member upon installation can be corrected through application of an electric current, or through heat, such as that created by an internal combustion engine. This heat forces the retaining member to retain a consistent shape, and a generally constant spring force, despite any eccentricities in the shaft or retaining member.
