Patent ID: 7562528

Claim:
A method of negotiating a turn in a low-flow-restriction fashion with a flow of exhaust gas that is exiting a turbine in a highly turbulent condition that has a general swirl structure, comprising the steps of: sealably routing the flow of exhaust gas from a gas outlet of the turbine into an inlet port of a housing; expanding and funneling the flow of exhaust gas in an inlet transition portion of an internal volume that is formed in the housing, wherein the inlet transition portion has an elliptical-conoid shape; passing the flow of exhaust gas out of the inlet transition portion into an outlet transition portion of the internal volume, wherein the outlet transition portion has an oblate-ellipsoid shape; exiting the flow of exhaust gas from the housing through an outlet port that fluidly communicates with the outlet transition portion, wherein the outlet port is at an angle with respect to the inlet port; and providing a structural rigidity to the turbine with the housing when the housing is connected to the turbine and to an engine.
