Assembly for removing oil ventilation air in a gas turbine engine

The arrangement has a breather pipe (10) which leads into a diffuser (13) integrated in an exhaust cone (9). The exhaust cone proceeds from an exhaust flow (A) of a gas turbine engine for conversion of a kinetic energy of an oil venting air into a pressure energy lying static above the exhaust gas flow pressure. An oil air outlet opening (14) of the diffuser is connected to the exhaust flow directly or by a setting chamber (18) formed in the exhaust cone.
