Abstract
A rotary compressor apparatus having a housing with a rotor eccentrically mounted therein and such rotor includes a plurality of sliding vanes which define constantly changing compression pockets as the rotor is rotated. The apparatus includes a plurality of ports which may be opened to permit full unloading when starting the compressor and which may be selectively closed to control the quantity of gaseous matter being compressed. The apparatus also includes a high pressure oil injector at each end of the rotor for sealing such ends to prevent loss of compression.
