| description | The invention discloses a supercharged ventilator, belongs to the technical field of aero-engine lubricating systems, and solves the technical problems of high structure circulation resistance of an existing centrifugal ventilator and/or insufficient sealing pressure difference and/or high lubricating oil consumption of an engine in a low-rotating-speed state. The supercharged ventilator is suitable for exhausting of an aero-engine; the aero-engine comprises a gear box; the gear box comprises a shell, and a transmission shaft arranged in the shell; a diffuser and a centrifugal compressor are adjacently mounted in the shell; the centrifugal compressor is mounted on the transmission shaft, and is provided with an oil-gas separation structure; the diffuser is fixedly mounted on the inner surface of the shell; the diffuser and the centrifugal compressor are connected in a sealing and communicating mode; an oil phase and a gas phase of an oil-gas mixture exhausted by the gear box are separated through the oil-gas |
