Abstract
An oil circulation system for a gas turbine engine includes a variable displacement scavenge pump for pumping oil, a first actuator for controlling displacement of the scavenge pump, a variable displacement pressure pump for pumping oil, a second actuator for controlling displacement of the pressure pump, and a drive shaft. Both the scavenge pump and the pressure pump are driven by the drive shaft.
