ABSTRACT:
A means of sealing a rotating shaft against high fluid pressure with low friction torques, low leakage and low wear. This accomplished by use of sealing assembly comprising a sliding and a floating seal assembly separated by a lubricant filled chamber. The sliding seal is exposed to the high pressure environment which is kept isolated from the drive means by the chamber. Thus, the high pressure environment leaks into the chamber rather than the environment of the drive means and the non-harmful lubricant leaks slowly into the drive means environment.
