  • System for pressuring the bearing chambers of turbine engines machines using air taken from the intake duct
    Patent number: 9540951
    Abstract: A system for pressurizing at least one chamber for lubricating bearings of a turbine engine, including a circuit for supplying the chamber with pressurized air, and a circuit for recovering oil mist formed in the chamber and for returning the mist to an oil tank of the turbine engine. The supply circuit supplies the chamber with air taken upstream from the low-pressure compressor.
    Type: Grant

  • Sealing system with annular brush seal
    Patent number: 8864138
    Abstract: The invention concerns a system for providing a seal between two volumes (V1, V2) delimited by a part (2A) mounted to rotate about an axis (A) and a stator (6), said system (S) including an annular brush seal (7) that comprises: a brush body (8) pivotally mounted in the stator; and fibers (10) fixed to the brush body and inclined at an angle ? relative to a plane (P) orthogonal to the rotation axis (A), wherein it includes means (11, 12) for adjusting the angle ? of the fibers (10) so as to be able to adjust precisely the clearance between the free end (10A) of the fibers and the rotary part (2A).
