  • Patent number: 3964753
    Abstract: A carbon ring seal for a shaft rotating at high speed is capable of preventing high temperature, high pressure gas from entering the oil system. The carbon seal is constructed so that at ambient temperature it works as a controlled gap seal, but when the seal runner reaches its full thermal growth the seal then functions as a positive contact seal. The carbon seal ring is retained by an anti-rotation pin extending through a slot in the ring. The carbon ring has a single fracture at the slot. The seal housing is provided with a plurality of calibrated holes for predetermined internal pressurization and cooling.
