ABSTRACT:
A seal arrangement for preventing leakage of a fluid from a high pressure region to a lower pressure region through a radial gap defined between a stationary member and a member rotating relative thereto. A stationary seal member is provided which substantially closes the radial gap but which defines a narrow radial clearance therebetween. Deflector seals are mounted on the rotating member and exhibit predetermined axial alignment with the stationary seal, the deflector seals extending radially outward from the rotating member for a distance less than the clearance defined between the stationary seal and the rotating shaft.
