Abstract
A seal structure between a circumferentially extending array of stator vanes and an outer case is disclosed. Various construction details that allow the seal structure to accommodate differences in axial and radial growth between the outer case and the vane array are developed. A continuous ring disposed between the vane array and the outer case cooperates with a first seal member to block leakage of working medium between the ring and the vane array. The continuous ring cooperates with a second seal member to block leakage of the working medium between the ring and the outer case.
