A de-oiler system for an aircraft engine including a casing defining a volume containing a rotary shaft and a mixture of air and oil for processing is disclosed. The system includes a hollow rotary axle; a de-oiler structure fastened to the hollow rotary axle and rotating together with the hollow rotary axle, the de-oiler structure having an inlet first face communicating with the volume and an outlet second face connected to a passage formed in the hollow rotary axle; and a transmission device between the hollow rotary axle and the rotary shaft for communicating to the hollow rotary axle a speed of rotation V about its axis in such a manner that the speed of rotation V is greater than a speed of rotation v of the rotary shaft.

What is claimed is: 1. A de-oiler system for an aircraft engine having a casing defining a volume containing a rotary shaft and a mixture of air and oil for processing, the de-oiler system comprising:a hollow rotary axle distinct from said rotary shaft;a de-oiler structure fastened to said hollow ro

What is claimed is: 1. A de-oiler system for an aircraft engine having a casing defining a volume containing a rotary shaft and a mixture of air and oil for processing, the de-oiler system comprising:a hollow rotary axle distinct from said rotary shaft;a de-oiler structure fastened to said hollow rotary axle and rotating together with said hollow rotary axle, said de-oiler structure having an inlet first face communicating with said volume and an outlet second face connected to a passage provided in said hollow rotary axle; anda transmission device between said hollow rotary axle and said rotary shaft for communicating to said rotary hollow axle a speed of rotation V about its axis in such a manner that said speed of rotation V is greater than a speed of rotation v of said rotary shaft, whereby the mixture of air and oil in said volume within said casing moves towards the inlet first face of said de-oiler structure to remove the oil contained therein and air is collected via said passage of the hollow rotary axle.
