ABSTRACT:
An annular fluid seal is provided between a pair of spaced apart machine components, such as a rotor and a stator. The rotatable component includes an annular sealing surface of increasing diameter in a given direction (e.g., along its length or along a radially extending shoulder). An annular fibrous sealing element is disposed proximate the clearance space between the components in such a manner that a sealing portion thereof engaging the other component moves in the direction of increasing diameter as the sealing portion may wear so as to maintain sealing contact with the annular sealing surface. A fluid seal is thereby maintained between the components.
