Abstract (en)
[origin: EP0892152A1] The housing is heated or cooled to adjust its diameter and, in particular, the clearances between the ends of rotating blades and itself. The device consists in tube networks (1) extending over matching portions of the housing circumference and made up of a couple of distributors (3) and parallel tubes (2) between these distributors, the tubes (2) being alternately connected to one or the other distributor and provided with orifices blowing gas towards the housing. The countercurrent circulation in the tubes (2) enables to blow on each of the housing generators both gas highly heated by a longer passage in the tubes (2) and cooler gas having travelled a shorter distance in other tubes (2), thereby balancing the heat supply on each housing portion.
