ABSTRACT:
A turbine cylinder is in contact at its outer surface with split rings which are held in place in annular slots in a cylindrically extending ring holder. The rings, while remaining in contact with the outer surface of the cylinder, are allowed to expand and contract within their respective slots. Notches are constructed at the inner circumference of the rings to form a labyrinth type cooling passage in conjunction with the outer surface of the turbine cylinder.
