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.

Abstract: A rotor for a compressor system includes a rotor body having a coolant manifold with an inlet runner and a plurality of coolant supply conduits extending from the inlet runner toward an inner heat exchange surface. The coolant supply conduits may have a circumferential and axial distribution, and extend through struts enhancing stiffness in the rotor body.

Abstract: A compressor includes a rotor having an outer compression surface and a plurality of inner heat exchange surfaces. A coolant supply manifold fluidly connects with a coolant inlet in a first axial end of the rotor, and delivers coolant fluid by way of conduits having an axial distribution in the rotor so as to deliver coolant fluid to the heat exchange surfaces. The coolant may be a refrigerant that undergoes a phase change within the rotor.

Abstract: An impact moisture separator for separating a liquid moisture from a compressed gas. The impact moisture separator includes a plurality of impact plates that are positioned within the inner region of the separator and may be downstream of at least one strut. The strut may be configured to disperse the flow of compressed gas. The impact plates each have a plurality of vanes that extend beyond a plate portion of the impact plates. The vanes are configured to provide a passage for the flow of compressed gases and are offset from the vanes of the adjacent, successive impact plate. Further, the impact plates and strut(s) are tilted toward the incoming flow of compressed gas so as to assist in influencing the downward flow of the compressed gas, and thereby facilitate the flow of separated liquid moisture toward a reservoir of the housing.
