FLUID COMPRESSION/EXPANSION MACHINE WITH FLUTED MAIN ROTOR HAVING RULED SURFACE ROOT AND METHOD OF MANUFACTURE

Fluid compressor or expander having a main rotor with discrete arcked-helical flutes that have ruled surface roots that match the predominantly planar tips of the teeth of the associated gate rotors and provide effective fluid sealing as the gate rotor teeth sweep through the flutes of the main roto...

description	Fluid compressor or expander having a main rotor with discrete arcked-helical flutes that have ruled surface roots that match the predominantly planar tips of the teeth of the associated gate rotors and provide effective fluid sealing as the gate rotor teeth sweep through the flutes of the main rotor during compressor or expander operation. The flutes can be readily and economically made by end milling, in which a first flute is milled with a minimized number of milling passes such as a first pass to make one arcked-helical flank and a portion of the arcked-helical root of a first flute and a second pass to make the opposing arcked-helical flank and another portion of the arcked-helical root of the first flute. Additional discrete flutes are made in a similar manner until the main rotor is completed.
