Abstract
An aircraft engine has: a compressor section having a compressor rotor rotatable about a central axis; a diffuser downstream of the compressor rotor, the diffuser including a diffuser ring extending circumferentially around the central axis; a bearing housing secured to the diffuser ring, the bearing housing contained within a volume located radially inwardly of the diffuser ring; and an air manifold secured to the diffuser ring, the air manifold defining inlets in fluid flow communication with the compressor section and an outlet in fluid flow communication with the volume.

An aircraft engine comprising:
- a compressor section having a compressor rotor rotatable about a central axis;
- a diffuser downstream of the compressor rotor, the diffuser including a diffuser ring extending circumferentially around the central axis;
- a bearing housing secured to the diffuser ring, the bearing housing contained within a volume located radially inwardly of the diffuser ring;
- and
- an air manifold secured to the diffuser ring, the air manifold defining inlets in fluid flow communication with the compressor section and an outlet in fluid flow communication with the volume.
A diffuser for a compressor section of an aircraft engine, comprising
- a diffuser ring extending circumferentially around a central axis, the diffuser ring having a radially inner end and a radially outer end;
- and
- an air manifold secured to the diffuser ring radially between the radially inner end and the radially outer end, the air manifold defining inlets in fluidly connectable to the compressor section and an outlet fluidly connectable to a bearing housing.
