ABSTRACT:
An oilless double rotor, rotary gas compressor with second stage inputs for precompressed gas is described. A compression rotor having at least three lobes which match in intersection to cavities in a counterrotating valving rotor providing an extended sealing surface. The lobes further provide an extended, near-contact surface with the housing with adjacent lobes defining successive compression chambers. Second stage ports are also provided for input of precompressed gas for use with energy recovery systems. A discharge equalization passage is provided in association with a discharge port for efficient gas exhaust.
