Abstract
Abstract A dynamoelectric machine with a mid-frame section and an endframe section has manifold means comprised of a mid-frame manifold and an end-frame manifold, each sealingly connected to the respective frame sections. A gas-carrying transition means for conveying cooling gas between the manifolds is sealingly connected to the manifold means. Sealing rails facilitate the attachment of the gas-carrying transition means to the manifold means and reduce the overall space occupied by the dynamoelectric machine.
