    摘要: A circuit and a method for feeding oil to rolling bearings in a turbomachine is disclosed. The circuit includes an oil supply; an oil duct connecting the supply to lubrication enclosures, each enclosure containing at least one rolling bearing; an oil feed pump located between the supply and the lubrication enclosures; an oil recovery pump connected downstream from each lubrication enclosure; a pressurizing valve placed in the duct between the oil feed pump and the lubrication enclosures, the pressurizing valve being adapted to open when the pressure at its inlet exceeds a predetermined threshold pressure; a branch connection duct connecting the inlet of the pressurization valve to one of the lubrication enclosures in order to feed it with oil; and a feeding device which feeds the lubrication enclosures at a small oil flow rate so long as the pressure at the inlet of the pressurization valve has not reached the predetermined threshold.

    摘要: A disclosed lubrication system for a gas turbine engine includes a primary passage defining a flow path for lubricant to a gas turbine engine and a bypass passage defining a flow path for lubricant around the gas turbine engine. The lubrication system further includes a primary lubrication pump including a reduced total flow capacity of lubricant with a reduced bypass lubricant flow relative to the total overall flow capacity.

    摘要: A system and method are provided to selectively control lubricant supply flow to one or more rotating machines in an aircraft when the rotating machines are windmilling. A controller determines if the rotating machines are windmilling. When the rotating machines are windmilling, the controller at least selectively energizes an electric motor driven lubrication pump, to thereby supply lubricant to the windmilling turbomachine.

    摘要: A lubrication system for a turbine generator includes a sump having a first chamber that receives oil from the turbine generator and a second chamber from which filtered lubrication oil is supplied to the turbine generator. The chambers are interconnected by a partition wall having a flapper valve in the wall allowing unfiltered oil to bypass the filtration loop should a malfunction occur in a pump that pumps oil through the filtration loop. The flapper valve allows unfiltered oil to travel directly from the first chamber to the second chamber and thence to be pumped through the turbine generator by one or more pumps contained within the second chamber.
