Patent ID: 7426834

Claim:
A method of assembling a gas turbine engine, said method comprising the steps of: providing an oil supply and scavenge system including at least one sump cavity that includes a first scavenge port and a second scavenge port; providing a first oil pump that includes a first oil supply element and a first scavenging element and a second oil pump that includes a second oil supply element and a second scavenging element; coupling the first oil pump and the second oil pump in flow communication with the oil supply and scavenge system, such that the first oil pump is in flow communication with, and receives scavenge oil from, the first scavenge port via the first scavenging element and such that the second oil pump is in flow communication with, and receives scavenge oil from, the second scavenge port via the second scavenging element; coupling the first oil supply element in flow communication to an oil supply source for receiving oil therefrom; coupling the second oil supply element in flow communication to the oil supply source for receiving oil therefrom; and coupling an output of the second oil supply element to the output of the first oil supply element to provide a combined output flow.
