    Abstract: A rotary gas compressor of the sliding vane type having a rotor positioned eccentrically within a working chamber provided by a cylinder in the stator housing which is closed by end plates secured to the housing. The rotor carries blades or vanes slidable within slots formed in the rotor to engage the cylinder and sweep the working chamber to compress gas introduced therein. The end plates are formed with arcuate, gas discharge slots connecting the outlet port of the housing with circumferentiallyspaced discharge slots in the rotor in a manner to provide an alternate, low resistance path for gas flow at a point located a substantial distance from the outlet port. This arrangement is effective to reduce the extremely high pressure which is normally generated in the discharge zone as the vanes approach the main outlet port and valve assembly.
