The principle of the sliding vane rotary compressor is based on a cylindrical rotor turning on two rolling bearings arranged eccentrically in the base, assembled on either side of the body of the machine, called the stator.
This mechanism consists of a crescent-shaped chamber: the compression chamber.
The vanes made out of a composite material slide freely in the radial grooves of the rotor and, when the mechanism is set in rotation, they are applied by centrifugal force against the inner surface of the stator. As the mechanism rotates, these vanes create volume-reducing cavities thereby creating the necessary compression.
Gas is drawn in through ports in the stator, on the part where the volume is increasing, and discharged through other ports located in an area where the volume is decreasing to a minimum.
