The machine has a shaft (20) rotatably mounted with respect to a casing (28) of the machine, and an active axial balancing system exerting an axial restoring force on the shaft. A circuit allows passage of a secondary liquid flow (F2) deducted from a main liquid flow. A passive axial balancing system (42) exerts an additional axial restoring force (R2) on the shaft, and is supplied by the secondary liquid flow circuit. The passive balancing system includes an annular passage (52) between the shaft and the casing, where the secondary liquid flow discharges via the passage. |
