Abstract
A high pressure compressor seal assembled onto a compressor shaft, together with compressor bundle elements. A stationary bundle vane is engaged with slots within the seal to prevent rotation of an outer portion of the seal during operation of the compressor. In addition, the stationary vanes engage groves in the seal so that when the bundle elements are inserted into the compressor, the seal can be pushed into a housing opening.
