Abstract

The invention relates to a distribution device (5) for suction gas, that comprises a distribution pipe (6) as well as bypass pipes (7) for establishing communication between the distribution pipe and the inner volumes (3) of cooling compressors (2). A device for normalising the suction gas flow is provided in the distribution pipe upstream of the bypass pipes (7).
