Abstract (en)
[origin: EP0626503A1] In order to avoid leaks of the fluid for lubricating the bearings (12a, 12b) of a turbomachine such as an aircraft turbojet engine, when the speed of this turbomachine drops below the idling speed, it is proposed to connect the chambers (20a, 20b) surrounding the bearings (12a, 12b) to free air via a pipe (48a, 48b) in which a jet pipe (49a, 49b) has been placed. The nozzle of this jet pipe is connected to a source of compressed air, such as the compressor (56b, 56a) of another turbomachine, via a valve (54a, 54b) which is made to open under the abovementioned conditions. <IMAGE>
