Abstract

En una máquina de flujo de fluido, especialmente una turbina de gas, penetrada axialmente por una corriente de gas caliente, el eje de rotor es rodeado por segmentos de escudo de calor o por placas base de las aspas de rotor en el lado del rotor. En los segmentos de escudo de calor y en las placas base, se proporcionan cámaras de enfriamiento de aire, que se comunican entre sí y con una fuente de aire de enfriamiento, estas cámaras se comunican por lo menos parcialmente con huecos que se extienden en la dirección longitudinal o la dirección periférica del eje de rotor entre aspas de rotor adyacentes o entre los segmentos de escudo de calor y placas base adyacentes de las aspas de rotor. Estos huecos se cierran mediante bandas de sello tal que una entrada de aire de enfriamiento en la corriente de gas caliente es solamente posible en los extremos de las placas base de las aspas de rotor que dirigen contrario a la dirección de flujo.
