Abstract
A self-adjusting non-contact seal for sealing the circumferential gap between a first machine component and a second machine component includes structure which undergoes wear in the event of inadvertent contact with one of the machine components in such a way as to allow a reset of its radial distance from such machine component, compared to initial installation tolerances, while minimizing leakage.
