<p>A centrifugal de-oiler of variable flow section, the de-oiler including a hollow shaft that is movable in rotation. The shaft includes at least one air-passing orifice and a piston housed in the shaft so as to subdivide the inside of the shaft into two compartments that are sealed relative to each other. One compartment includes the air-passing orifice(s) being subjected to ambient pressure, and the other compartment is subjected to varying pressure in the air/oil enclosure. The piston is configured to move in translation inside the shaft between two extreme positions under effect of the pressure difference between the two compartments, the extreme position including a first position in which the air-passing orifice(s) is/are disengaged, and a second position in which the air-passing orifice(s) is/are partially obstructed by the piston.</p> |
