ABSTRACT:
A seal device for a Lysholm compressor has a carbon seal ring and a metal maintaining ring arranged peripherally of a shaft of a male or female rotor, the seal ring being pressed against the maintaining ring to achieve sealing. Square root of a sum of square of surface roughness of the seal ring and square of surface roughness of the maintaining ring is in the range of 0.8 to 2.5 Z, which prevents occurrence of blisters on a surface of the seal ring and leaked oil amount can be within the leakage permissible level.
