A system for sealing an oil chamber from an adjoining exterior volume and turbo-machine provided with such a sealing system. According to the invention, the system for sealing the oil chamber (1, V1) from the adjoining exterior volume (V2), both of which are delimited by a mobile rotor in rotation (5) about an axis (L-L) and a part, fixed or mobile (7), comprises: a first seal (10A) arranged between the rotor (5) and the part (7); a second seal (10B) that is mounted between the rotor (5) and the part (7) and which is offset longitudinally relative to the first seal (10A), so as to form with the first seal a sealing chamber (12) delimited by the rotor (5), the part (7) and the two seals (10A, 10B); and means (13) for supplying gas (G) to the sealing chamber (12), such that the gas (G) can be compressed when the rotor (5) begins to rotate, the chamber communicating with the oil chamber and/or the adjoining exterior volume via the first and second seals alone, respectively.
