Abstract
A gas compressor is disclosed that includes a first rotor having a first rotor body, the first rotor body including a plurality of helical lobes, an infernal volume within the first rotor body defined by a wall, and a turbine disposed within the internal volume, the turbine including a turbine body and a plurality of airfoils extending substantially radially from the turbine body to the wall, where the internal volume is structured to enable a cooling fluid to flow therethrough. The gas compressor further includes a second rotor body including a plurality of helical flutes, an inlet manifold and an outlet manifold, both disposed within the second rotor body, and a body channel within at least one flute extending from and in fluid communication with the inlet manifold to the outlet manifold, where the body channel is structured to enable a cooling fluid to flow therethrough.
