ABSTRACT:
Layout for adjusting the diameter of a turbine engine ring (5) positioned facing mobile rotor blades (4) and connected to a case element (7). The latter is provided with a cavity (16) communicating with chambers (21, 23) around a gas flow stream (31). A limited air current traverses the cavity (16) and is sufficiently reduced to ensure the development of a heat convection, which renders uniform the temperature of the case element (7) and the ring (5) and consequently the diameter of the latter.
