Abstract: The present disclosure is directed to a screw compressor system having a compressor housing with a pair of screw rotors rotatably supported within a compression chamber. Lubricant is injected into a compression chamber at a first volume ratio and at a second volume ratio greater than the first volume ratio to increase the sealing and lubrication between the screw rotors and rotor bores in the compressor housing as well as to increase heat transfer from a compressed working fluid in the compression chamber.

Abstract: A compressor is disclosed which can include a first stage and a second stage. In one form the compressor includes contact cooled compressor stages. The compressor can include a rod useful to inject a lubricant for purposes of cooling/lubricating/sealing the rotating components of the compressor. In one form the rod is an elongate rod with openings which permit a lubricant such as oil to be injected. The injected oil can be atomized via the openings. The rod can be positioned in the interstage space between the first and second stages, and can include a variety of openings.

Abstract: The present disclosure is directed to a screw compressor system having a compressor housing with a pair of screw rotors rotatably supported within a compression chamber. Lubricant is injected into a compression chamber at a first volume ratio and at a second volume ratio greater than the first volume ratio to increase the sealing and lubrication between the screw rotors and rotor bores in the compressor housing as well as to increase heat transfer from a compressed working fluid in the compression chamber.
