ABSTRACT:
A centrifugal-type ejector machine of the invention comprises a sealed housing with a rotating rotor. The interior of the housing is filled with a liquid. The rotor has a central axial opening and is provided with a plurality of radial channels leading to the outer periphery of the rotor in a substantially tangential direction to the rotor periphery. The device operates as a compressor or a vacuum chamber based on the principle that difference of speeds between the periphery of the rotating rotor and stationary liquid created a negative pressure at the exit of radial channels of the rotor connected to the source of gas, which is extracted from the channels of the rotor into liquid and is removed through the outlet port of the compression chamber. In case the device works as a vacuum chamber, evacuation occurs through the aforementioned radial channels and the hollow shaft of the rotor.
