Patent ID: 7874158

Claim:
A compressor diffuser and dirt separator for a gas turbine engine comprising: a diffuser housing with an inlet having a first cross-sectional area and an outlet having a second cross-sectional area, said second cross-sectional area being greater than said first cross-sectional area; and a dirt separator positioned near a downstream end of said diffuser housing, and adjacent said outlet, said dirt separator being operable to separate heavier dirt laden air to radially outer locations, and relatively cleaner air to radially inner locations, and such that the majority of the heavier dirt laden air, which is radially outward of said dirt separator is directed radially outwardly of a radially outermost surface of a combustion section to be mounted downstream of the diffuser, and such that air from a radially innermost location is directed toward the combustion section, and such that the air which does move into an interior of the combustion section to be mixed with fuel and burned is air from a location radially inward of said dirt separator.
