Abstract
The improved shaft seal assembly is disclosed in having the sealing device lodged simultaneously in a female recess in the rotor and stator. The mating relationship of a solid deformable annular seal in opposed recesses in the stator and the rotor results in the rotor and stator being locked together thus preventing axial movement between the rotor and stator. The novel seal assembly will be a positive seal during operation and also will prevent leakage when at rest.
