The invention relates to a system for keeping oil in the casings of compressors operating in parallel. It comprises a common reservoir 1, the oil return tubes 2 via which the excess oil returns to the reservoir, the reinjection tubes 3 taking oil from the bottom of the reservoir and opening out into the casing of the compressor. The oil is taken back up and sprayed by the expansion of the gases taken from the delivery by the capillary tube 4. <IMAGE>
