IMPROVED SEALING RING FOR GAS TURBINE ENGINES

摘要

A sealing ring for controlling gas leakage through the annular space between two rotating concentric members; for example engine shafts. The sealing ring 20 has a generally trapezoidal cross section, and an overlapping scarf joint. The sealing ring improves sealing by providing continuous lines of contact at edges 26 and 28 between inner and outer coaxial shaft members 14 and 16 respectively.
