Elastic fluid turbine employing a sealing ring

摘要

A segmented seal ring and spring system for steam turbines for minimizing leakage between rotating and stationary components, and preventing damage and wear thereto, including a segmented seal ring, with special springs biased against the seal segments to urge the segments radially inwardly toward the small clearance position of the seal ring with respect to the turbine shaft, also with secondary springs to counter the weight of the segments; with the combination of said springs gently urging the seal segments into the small clearance position while allowing clearance enlargement with small resulting forces on the shaft during periods of misalignment and rubbing. <IMAGE>
