Abstract:
1. A separator for separating oil mist from crankcase ventilation gas of an internal combustion engine, with a gas purification chamber inside which a rotatably mounted centrifugal rotor is arranged, the gas purification chamber having a crude gas inlet, a pure gas outlet, and an oil outlet, the crankcase ventilation gas is conducted into a radially internal zone of the centrifugal rotor via the crude gas inlet, while pure gas liberated from oil mist is discharged from the gas purification chamber via the pure gas outlet, and oil separated from the gas is discharged from the gas purification chamber via the oil outlet, the separator comprises a rotary drive for the centrifugal rotor, the rotary drive being arranged in a drive chamber of the separator, the drive chamber being separately arranged from the gas purification chamber, and the rotary drive is operated using pressurized lubrication oil of the internal combustion engine and is connected to the centrifugal rotor by means of a shaft extending from the drive chamber into the gas purification chamber, the rotary drive is formed by at least one thrust nozzle which is connected to the shaft and to which the pressurized lubrication oil of the internal combustion engine can be fed, wherein at least one part of a base that forms the separation between the gas purification chamber and the drive chamber extends into the drive chamber, the one part of the base being fitted with a seat for a bearing of the shaft, the bearing being located at a distance from the centrifugal rotor, wherein two bearings bearing the shaft are spaced apart from each other and arranged in the base.
