APPARATUS FOR GAS-LIQUID SEPARATION AND ITS USE IN THE ELIMINATION OF OIL FROM BEARING-CASING AIR IN TURBO MACHINERY

摘要

The gas-liquid separation device consists of two concentric pipes rotationally driven about their common longitudinal axis and between them defining first and second longitudinally extending channels. The mixture is passed into the first channels and the second channels collect and evacuate the liquid particles which have been separated from the gas in the first channel. The device may be mounted within a shaft of a turboengine and be used to de-oil the ventilating air of turboengine bearing cases. It may be combined with a mounting sleeve which also serves to distribute the lubricating oil of the bearings within the case.
