摘要：
With an arrangement for the discharge of oil-contaminated exhaust air separated from the lubricating oil de-aeration system of a gas-turbine engine and led to the atmosphere via a venting line, the venting line (13) issues into an attenuation chamber (12) formed within the exhaust cone (9) of the gas-turbine engine and connected to a Venturi nozzle (14) via a discharge tube (17) for drawing off the oil-contaminated exhaust air and blowing it into the exhaust-gas flow, with the Venturi nozzle (14) being arranged in the exhaust gas-flow of the gas-turbine engine and oriented in a flow direction. The oil-contaminated exhaust air is completely discharged with the exhaust-gas flow without contacting visible engine parts.
