Abstract
A unitary exhaust gas housing for a turbo-engine comprises an outer ring, two intermediate rings defining the flow path for the hot gases, and an inner ring forming a hub with a hollow annular chamber. A temperature control device is provided including a bleed tube having one end fixed and communicating with the gas flow path for drawing off hot gases therefrom, the other end of the tube passing into the hollow chamber of the hub where it regulates the flow of gases by variation of the clearance j between the end of the tube and the opposing wall of the hub in response to relative radial movements of the tube and the hub according to the thermal states of the assembly.
