ABSTRACT:
A self aligning ring seal for sealing a rotating member such as a shaft of a gas turbine relative to the housing. The ring seal includes a housing retaining a static, resilient seal. A seal plate engages the resilient seal and the seal plate has a curved peripheral edge which permits movement of the seal plate relative to the housing. An annular ring seal assembly extends about the shaft preferably of a carbon or other temperature-resistant material held in compression by an outer compressing ring. The ring seal assembly has a sealing face engaging the seal plate. In the event of shaft misalignment, the sealing faces of the seal plate and ring seal assembly remain in substantially full sealing contact with the misalignment being translated to the static seal.
