The invention relates to a device (1) for separating an air/oil mixture comprising an air/oil mixture inlet (8), an oil receiving chamber (9), an air circulation duct (11), at least one filter element (21) rotatably coupled to a rotating drive shaft (12), the device (1) being designed so that the mixture from the above-mentioned inlet (8) opens into the chamber (9) and is driven through the rotatably driven filter element (21), so that the oil contained in the mixture is centrifuged radially outside the filter element (21) and fed into the oil receiving chamber (9), the filtered air opening into the air flow line (11), characterized in that the rotating drive shaft (12) is coupled to a turbine (26) capable of being driven in rotation by at least part of the filtered air flow, the turbine (26) comprising an outlet (29) of the filtered flow which opens to the outside.
A device for separating a flow from an air/oil mixture comprising a flow inlet, an oil receiving chamber, an air circulation duct, at least one filter element rotatably coupled to a rotating drive shaft with a longitudinal axis, the separation device being designed in such a way that the flow from the above-mentioned flow inlet opens into the chamber and is driven through the rotating filter element, so that the oil contained in the flow is centrifuged radially outside the filter element and fed into the oil receiving chamber, the filtered flow opening into the air flow line, characterized in that the rotating drive shaft is coupled to a turbine capable of being driven in rotation by at least part of the filtered flow, the turbine comprising an air outlet which opens out.
