Title: LUBRICATED ENCLOSURE FOR AN AIRCRAFT TURBINE ENGINE, LIMITING THE RETENTION OF LUBRICANT DURING PITCHING
Abstract:
The invention relates to a lubricated enclosure (A) for an aircraft turbine engine, comprising a drained roller bearing (28) provided with drainage orifices (34), as well as a lubricant ejector (60) intended to limit the retention of lubricant in a critical zone (80) of the enclosure, the ejector being intended to be passed through by a primary lubricant flow (Fp) in order to drive a secondary lubricant flow (Fs) located around a nozzle (72) of the ejector housed in the critical zone (80) of the enclosure. According to the invention, the enclosure comprises a device (52) for establishing communication between the drainage orifices (34) and the ejector (60), such that the lubricant that escapes from the drainage orifices supplies the ejector in order to form the primary flow (Fp).
