An oil and evacuation turbomachine comprising such a device

An oil discharge device of an enclosure (21) of the oil located in the downstream part (9) of a gas turbine engine, said device comprising a discharge means (30) at least a portion of the oil (20) contained in the outward chamber (16) of the engine, and drive means (1 1A, 12A) of oil capable of passing a air flow (40) the flow of which is involved in driving the evacuation of oil outwardly from said engine. In this device, the drive means (11A, 12A) comprise a ventilation hole (10A) formed in the downstream part (9) of said engine so that the oil takes said orifice (10A) and a guide member (50) arranged so that the oil, after taking said vent port (10A) is directed towards the downstream purge zone (16) of the low pressure turbine (15). The invention also relates to a turbomachine including such an oil discharge device.
