| 摘要 |
The invention relates to a circuit and a method for feeding oil to rolling bearings in a turbomachine, the circuit comprising an oil supply, an oil duct connecting the supply to lubrication enclosures, each 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, and a pressurizing valve placed in the duct between the oil feed pump and the lubrication enclosures, said 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 means for feeding 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. |
