Rotary machine with non-positive displacement usable as a pump, compressor, propulsor, generator or drive turbine

A rotary machine for displacing fluids comprising:

• a housing having a fluid inlet at one axial end thereof and a fluid outlet at its opposite axial end, said housing generally symmetrical about a longitudinal centerline extending between said inlet and said outlet;
• a rotor within said housing including at least one blade and at least one paddle and extending from said inlet at a position generally coincident with said centerline to said outlet at a position generally radially spaced from said centerline;
• said paddle being a generally flat element having a width extending between inner and outer edges thereof and twisted about its length into an Archimedes screw spiral having a pitch between adjacent turns which decreases from said inlet to said outlet, said paddle's inner edges defining a conically shaped space within said housing as said paddle extends from said inlet to said outlet;
• said blade being a generally flat element having a width extending between inner and outer edges thereof and twisted about its length into in Archimedes screw spiral having a pitch different than that of said paddle;
• said outer edge of said blade affixed to said inner edge of said paddle at discrete length positions of said blade;
• and
• shaft means affixed to said blade for rotating said rotor relative to said housing for driving fluid between said housing and said paddle to cause said blade to channel the fluid into said space at said outlet.
