SCROLL COMPRESSOR Russian patent published in 2018 - IPC F04C18/02 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, namely, to the spiral type rotary compressors. Compressor comprises housing and rotor with spirals. In the rotor center a driven spiral is installed, made in the form of adjoining each other discs 6, 7 by the spiral surfaces facing towards the driving spirals 8, 9. Directed to the rotor support discs by the rear sides and mounted in the rotor in pairs with disks 6, 7, driving spirals 8, 9 are located on parallel axes, which are offset relative to each other. Rotor support discs are connected to the spirals 8, 9 by the mounted on the coupling elements 15 rolling bearings, through which located inside the cups spirals 8, 9 are interconnected through the bushings 16. Each of the cups is formed by the supporting end portion and equipped with the U-shaped notches side surface. Coupling elements 15 ends are equipped with supporting bearings, each of which is installed with possibility to move in the corresponding window. Windows are evenly arranged around the rotor spiral and support discs circumference and are made in the form of through holes. Disks 6, 7 are connected to the rotor support discs by means of provided with spacer bushings 12 coupling elements.

EFFECT: invention is aimed at provision of reliability and increased efficiency.
