Claim 0:
1. A part for a centrifugal breather for an air/oil mixture of a turbomachine, the part being configured to rotate about a longitudinal axis of symmetry, the part forming an annular enclosure, the annular enclosure being for centrifugal separation of said mixture and comprising:
an axially oriented inlet configured to feed said mixture,
a first radially inwardly oriented outlet providing an exit of oil-free air separated from said mixture and
at least one second radially outwardly oriented oil outlet oriented radially outwards and configured to discharge oil separated from said mixture to an area outside of the breather, the enclosure further comprising:
at least one mesh structure occupying at least one space in a duct which closes communication between the axial inlet and the internal radial outlet, wherein the mesh structure is formed by spatial repetition of at least one of a material and a void, a single pattern being produced by an interconnection of simple shapes comprising at least one of spheres, ovoids and bars of constant section, circles, rectangles and octagons, said pattern being arranged so that the voids define paths crossing through the materials in at least three dimensions of space forming a trihedron, and in that porosity of said mesh is of 95%.
