Rotary fluid-handling mechanism
First Claim
1. Rotary fluid-handling mechanism, comprising a rotor cylindrically recessed internally from one end therof and provided with power transfer means;
- a stationary cylinder closely and sealingly fitted within the rotor recess;
means for fixedly mounting said cylinder relative to said rotor;
means holding said rotor on said cylinder;
at least one pair of oppositely disposed, helically oriented cavities in the rotor, opening at the interior cylindrical surface thereof in confronting relationship with the cylindrical surface of said stationary cylinder;
at least one corresponding pair of blades;
means independently rotatably mounting said blades within and at diametrically opposite sides of said stationary cylinder on respective axes at right angles to the axis of rotation of said rotor, so portions thereof will enter and pass through the respective cavities during synchronized rotation of said blades and said rotor;
means for synchronizing rotation of said blades and said rotor;
means for providing inflow of fluid internally of said mechanism into the paths of advancing movement of said blades within said cavities; and
means for the discharge from the mechanism of fluid acted upon by said blades;
said means for synchronizing comprising a single shaft extending axially in the stationary cylinder;
means in said cylinder journaling said shaft, and gearing interconnecting said shaft and said means mounting said blades; and
said means for providing inflow of fluid internally of the mechanism including diametrically opposite passages flanking said shaft and said synchronizing means and extending from inflow ports at one end of the stationary cylinder along said shaft toward the opposite end of said cylinder.

Abstract
A rotary mechanism for handling fluids in various ways, e.g. as an air compressor, pump for liquids, hydraulic or air motor, internal combustion engine (diesel or otherwise), has a rotor internally cylindrically recessed from one end to receive, in close fitting, sealing relationship, a stationary cylindrical support for a plurality, usually a pair, of rotary blades. The rotor is provided internally with a corresponding plurality of cavities helically oriented to receive portions of the respective blades which enter and pass through the respective cavities for compressing or propelling the particular fluid concerned, depending upon the particular nature of the mechanism. Inflow and outflow ports for the fluid are variously arranged in either the stationary cylindrical blade support or the rotor or both depending again upon the particular nature of the mechanism. Various arrangements are provided for maintaining blade and rotor rotation in synchronism. The mechanism may be used in various ways in conjunction with other mechanisms. Thus, for example, it may be incorporated in an electric motor or generator, in an airplane to provide propulsion by propellers or jet, and in a stationary power source. It may also be used as the blood pumping unit of an artificial heart.
