ABSTRACT:
A positive clearance radial face seal characterized in that at least one of its two opposed sealing faces comprises a pressure-deflectable elastic or elastically loaded element which deflects, in steady state operating conditions, to provide a clearance between the sealing faces which converges in the radial direction towards the downstream zone of the seal, the deflection changing with variations in the operating conditions in a manner tending to restore the steady state clearance.
