Abstract

Obturación de escobillas para turbomáquinas. Se describe una obturación de escobillas para turbomáquinas, prevista para la obturación de espacios a diferente presión junto a una ranura periférica, especialmente entre un estator de máquina y un rotor de máquina, estando previsto en el estator de la máquina un soporte para el haz de cerdas, desde el cual el haz de cerdas es guiado entre almas periféricas de forma obturante contra el rotor de la máquina y que configura una ranura axial en dirección periférico frente a una de las almas vuelta hacia el lado de presión elevada. Para ello, el haz de cerdas debe presentar, al menos en el lado vuelto respectivamente hacia el espacio de presión más elevada en la obturación, elementos de apantallamiento o un dispositivo para disolver una corriente en remolino creada por el rotor de la máquina.
