ABSTRACT:
A seal assembly for sealing between a housing component and a rotating shaft. The seal assembly comprises a pair of relatively rotating rings defining a seal interface. One ring is stationary relative to the housing component. A flexible compressive seal element is compressed axially between the housing component and an axially movable biased compression ring to urge it into radial compressive sealing contact with a cylindrical surface on the stationary ring.
