  • Turbo-machine with device for automatically controlling the rate of flow of turbine ventilation air
    Patent number: 4805398
    Abstract: A device for automatically controlling the rate of flow of turbine ventilation air in a turbo-machine comprises two superimposed ceramic rings which are split and are each fixed at a single point to a metal support so that differential expansion of the support and the two rings in response to the operating conditions of the turbo-machine causes the registry of peripherally disposed slots in the ceramic rings to vary and thereby control the rate of ventilation air flow therethrough in accordance with the turbo-machine operating conditions.
