Abstract: A scavenge gear pump and its method of operation is described. The scavenge gear pump defines a pump chamber in which a pair of toothed gears are rotatably driven to pump an oil-air mixture from an inlet passage where the oil mixture is at low pressure, to an outlet passage where the air and oil has separated and is at high pressure. The gears are intermeshed in a meshing area between the inlet and the outlet passages and an oil nozzle is provided in a downstream region disposed in relation to the gear meshing area to inject oil under pressure in that area to occupy the volumes between the intermeshed gear teeth whereby to prevent air bubbles from being carried back to an upstream region adjacent the inlet passage. Accordingly, the volumetric efficiency of the pump is improved and it is more tolerant to back pressure.

Abstract: A scavenge gear pump and its method of operation is described. The scavenge gear pump includes a pump housing defining a pump chamber, an inlet passage, an outlet passage, and a fluid injection passage in fluid communication with the pump chamber. The inlet passage receives an admixed fluid at low pressure and the outlet passage the admixed fluid at high pressure from a downstream region of said pump chamber. The fluid injection passage receives a third fluid at an injection pressure for input into the pump chamber. A pair of driveable gears is disposed in the pump chamber. The third fluid is injected directly into the gear meshing area of the pump chamber through the fluid injection passage so that the third fluid fills voids at least between said intermeshing teeth of the driveable gears and so that the second fluid does not occupy the gear meshing area.
