  • Oil-air separator
    Patent number: 4981502
    Abstract: An oil-air separator having feed blades secured for rotation with a hollow rotor mounted for rotation in a stator housing with the formation of an annular space therebetween. The stator housing has an inlet for an oil-air mixture and an outlet for oil which is separated from the mixture. The feed blades are adapted to suit the contour of the annular space and ensure good separation of the air from the oil while achieving a high outlet oil pressure. The air which is separated from the oil-air mixture flows through a porous layer on the hollow rotor into the hollow rotor for external discharge therefrom.
