ABSTRACT:
A seal for a rotary compressor comprises a casing, at least one assembly having a rotating seal face ring which rotates as one with a sleeve intended to be mounted on a shaft of the compressor and of a stationary seal face ring mounted on the casing, the seal face rings being urged to press against one another via their rubbing face. The seal design further incorporates fluid circulation for heating leaks of compressible fluid conveyed by the compressor that occur between the seal face rings, this fluid circulation being formed in the casing and extending at least partially downstream of the seal face rings with respect to the direction of flow of the fluid stream.
