1. The invention concerns a system for lubricating seals of revolving shafts; the system comprises a lubricating fluid tank, connected to the separating space filled with this fluid; the separating space is limited by a fixed external casing for sealing rings, the number thereof being two at least, and the sealing rings slide on the shaft; whereas a circulator is located in the separating space, the circulator operating end mates with the revolving shaft surface, characterised in that in the external casing (1) of the sealing rings (2), two passages were made towards the separating space (3); the first passage (4), made in the lower part of the casing (1) is connected with the sediment tank (6) located below, while the other passage (5), made in the upper part of the casing (1), is connected with the lubricating liquid equalizing tank (7), whereas, in the second passage (5), the sleeve-shaped circulator is loosely located, the circulator operating end nearly contacts the revolving shaft, and the sediment tank (6) is connected with the equalizing tank (7).<IMAGE>
