A turbomachine compressor, including an air bleed device including a duct having a suction end opening out into an outer casing of the compressor level with a rotor wheel and a stator stage of the compressor is disclosed. A screen sheet of annular shape is mounted radially inside the casing facing a portion of the suction end of the duct so as to make the bleeding of air uniform over 360&#xb0; around the axis of the compressor.

Device for bleeding air from a turbomachine compressor

The invention relates to a turbomachine module comprising a device to improve radial clearances, comprising an outer casing (), an inner casing () and at least one shock absorbing ring () connecting the casings, the module also comprising an annular cavity () on the downstream side of the ring (), with a passage () formed in it through which an airflow () is drawn off from the primary flow (Fp). According to the invention, the device to improve radial clearances comprises a thermal inertia control device for the shock absorbing ring mounted on the shock absorbing ring (), downstream from it, this device comprising at least one coat of thermal insulation (), and at least partly delimiting the annular cavity () on the downstream side of it ().

Turbomachine module provided with a device to improve radial clearances

A bearing for a turbomachine variable pitch stator vane pivot mounted in a bore of the turbomachine casing is disclosed. The bearing includes an inner bushing secured to the pivot and an outer bushing secured to the bore. An elastomeric material is inserted between the inner bushing and the outer bushing to allow the vane to pivot about its axis and absorb at least some of the flexing of the pivot at right angles to the axis. The design makes it possible to reduce bearing bushing wear.
