Abstract
A centrifugal deaerator for an air/oil mixture of a turbine engine includes: an annular housing arranged around a hollow shaft and having an outer annular wall and an inner annular wall; axial mixture inlets for the inflow of the air/oil mixture into annular housing; a pinion for rotating the annular housing, the pinion including a web that is securely connected to the hollow shaft and to the inner and outer annular walls; radial oil outlets in the outer wall; and oil-free air outlets in the inner wall. The axial mixture inlets and the radial oil outlets are axially arranged on either said of the web to prevent the axial mixture inlets from reintroducing oil evacuated by radial oil outlets into the annular housing.
