Patent ID: 7249460

Claim:
An apparatus for increasing the efficiency of fuel combustion within a turbine engine by decreasing the size of the fuel cells to be combusted that are supplied to the engine combustion chamber comprising: a) an inner air passageway housing comprising: (1) at a first end an air inlet port having a first diameter; (2) walls connected to and extending from the air inlet port said walls forming the sides of the air passageway and sloped inwardly to decrease the diameter of the air passageway; and (3) at a second end an air exit port having a second diameter substantially less than the first diameter of the air inlet port; and b) an outer housing connected at one end to the first end of the inner air passageway housing and surrounding and separated by a space from the inner air passageway housing creating a chamber about the inner air passageway housing further comprising: (1) an inner wall tapered inwardly with decreasing diameter to form a generally conical inner surface of the chamber with the air exit port of the inner airway passageway housing truncating the end of the generally conical inner surface of the chamber; (2) a substantially cylindrical outer wall that narrows opposite the air exit port of the inner air passageway housing to create a narrow gap between the inner and outer walls of the outer housing adjacent the air exit port of the inner air passageway housing; (3) an air outlet port formed by the inner and outer walls of the outer housing that flare outwardly from the narrow gap increasing in diameter so that the air outlet port of the outer housing is substantially greater in diameter than the diameter of the air exit port of the inner air passageway housing; and (4) a fuel injector mounting port extending through the outer wall of the outer housing.
