Abstract
An oil scavenge system for use in a generator or the like which includes a housing having a plurality of isolated compartments into which oil may leak from the coolant flow passages of the generator. A plurality of fluid jet pumps are mounted in respective internal cavities about the housing of the generator. At least one internal passageway in the housing communicates each isolated compartment with one of the fluid jet pumps, whereby oil leaking into a compartment can be withdrawn therefrom by the respective jet pump. An internal conduit in the housing delivers oil under pressure to each fluid jet pump for operating the pump. An internal flow passage in the housing from the jet pump returns the oil to an engine gearbox pump.
