Abstract

See full text

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.
