Abstract
A device for adjusting the clearance between moving blades and the ring of a turbine wherein the ring includes a cylindrical sleeve, a perforated partition, and a wall, which together form an enclosure. Boreholes receive tubular elements which fit together with coaxial boreholes provided in opposite walls of a distribution chamber. The chamber communicates with pipes which admit heat regulating air. Alternating tubular elements traverse the perforated wall and the chamber to evacuate exhaust gas through pipes.
