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.
