Zusammenfassung:	A method and device for the autolubrication of the rolling bearings of turbomachines. The method and device utilize pressure differences present in the turbomachine for sucking in the lubricating oil. Moreover, a pressure is built up in centrifuges arranged on a shaft, and is used for the direct injection of the lubricating oil into the rolling bearings. For this purpose, an annular element imparting a negative pressure is arranged stationarily on the shaft, and is designed as a negative pressure chamber. The negative pressure chamber is connected via an oil suction conduit to an oil sump holding the lubricating oil and via a first air conduit to a negative pressure region of the turbomachine. The oil sump is connected via a second air conduit to an overpressure region of the turbomachine. A separating point is arranged between the oil suction conduit and the negative pressure region, preferably in the first air conduit.
