    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.
