摘要

A system for recovering the lubricating oil for the bearings of a centrifugal compressor (1) with labyrinth seals (9), in which the discharge pipe (19) of the chamber (17) facing the bearing (8) on the compressor delivery side is connected to the top or roof of an underlying sealed collection vessel (13), whereas the discharge pipe (18) of the chamber (16) facing the bearing (7) on the compressor suction side extends within said sealed vessel (13) to below the free surface of the oil.
