A centrifugal degasser of an air-oil mixture of a turbine engine includes a hollow shaft extending along an X axis and a pinion for rotating the hollow shaft, and an annular chamber for centrifugal separation of the mixture. The chamber is arranged around the hollow shaft and forms a fluid passage area, an inlet of which is oriented axially for feeding the chamber with the mixture, and a first outlet of which is oriented radially inwards for the outlet of the de-oiled air separated from said mixture. The chamber also includes at least one second oil outlet oriented radially outwards and configured for discharging the oil separated from said mixture to the outside of the degasser. The chamber and the pinion form a single piece.

Integral centrifugal degasser

A component for a centrifugal deaerator for removing gas from a turbomachine air/oil mixture includes a structural part configured to delimit a duct for the flow of the air/oil mixture, and includes a circumferential enclosure for the centrifugal separation of the air/oil mixture, an axial inlet for the air/oil mixture, radial oil outlets, and an outlet for oil-free air. The component includes at least one cellular structure configured to filter the oil while allowing the air to pass and occupying at least a space in the duct.
