Arrangement for the discharge of ventilation air separated from the lubricating oil de-aeration system of a gas-turbine engine

The arrangement has a breather pipe (13) which leads into a setting chamber (12) formed inside an exhaust cone (9) of a gas turbine engine. A venture nozzle (14) is positioned in an exhaust gas flow of the gas turbine engine, and is arranged in the flow direction. The venture nozzle is connected to the setting chamber by a discharge pipe for removing the exhaust air.
