Abstract
A rotary machine having a cavity in the form of a doubly truncated sphere having a rotor of hollow construction mounted therein, the cavity being symmetric about a vane axis which is canted with respect to the rotor axis. The rotor includes an integral Saturn-like ring extending symmetrically about its axis dividing the cavity into first and second sides each of annular wedge shape having thick and thin portions arranged in complementary fashion. The rotor has four radial slots aligned with the shaft axis to divide the rotor into 90 degree sectors, the slots being occupied by first and second blades with each blade defining a pair of vanes which separate the sides of the cavity into successive chambers which vary cyclically in volume as the shaft rotates. A relatively thin auxiliary shaft extends axially through the hollow of the rotor. An auxiliary centering ball is telescoped over the auxiliary shaft at the point of intersection of the axes. For engaging the ball the blades have at their centers respective C-shaped recesses facing mutually inwardly in overlapping relation, each recess being radially dimensioned to snugly embrace the ball in the longitudinal dimension thereby to k…
