Abstract
A seal is disclosed for a shaft journalled to rotate within a sleeve. The seal comprises annular members mounted between the shaft and the sleeve for relative movement along an axis common to the shaft and the sleeve. The members are biased into sealing engagement with each other and are separable by fluid pressure for relative rotation of the shaft and the sleeve with no surface-to-surface wear of the seal.
