ABSTRACT:
A shaft seal assembly adapted for installation on and concentrically with a rotary shaft for sealing off a chamber laden with a gas/liquid mixture from a space situated externally of the chamber. The assembly has a chamber side and an air side and further comprises a sealing lip circumferentially surrounding a stationary part of the assembly; a labyrinth sealing ring situated axially adjacent the sealing sleeve on the chamber side of the assembly. The labyrinth sealing ring comprises a rotary wall component and a stationary wall component together defining a labyrinth gap formed of a plurality of consecutive axial and radial passages for guiding the mixture in a path having a plurality of radial and axial deflections. The shaft seal assembly further has a liquid return device situated between the sealing lip and the labyrinth sealing ring as viewed along a path of propagation of the mixture in the assembly; and a radially oriented, operationally stationary return channel situated between the sealing lip and the labyrinth sealing ring for returning liquid from the assembly into the chamber in a radially outward direction.
