ABSTRACT:
A spherical rotary machine which may be embodied as a pump, internal combustion engine, compressor or similar other device includes an outer shell with a substantially spherical interior surface, an inner shell including a substantially spherical outer surface centered within the outer shell, and six rotary pistons located between the inner and outer shell. Each piston is rotatable about its own central axis, the six axes being orthogonally centered on the center of the machine. Each piston includes a top convex spherical surface conforming substantially in shape to and located adjacent to the spherical interior surface of the outer shell, a bottom concave spherical surface conforming substantially in shape to and located adjacent to the spherical outer surface of the inner shell, and an oval conical side surface which is substantially defined by lines which are substantially radial with respect to a point near the machine center. The oval side surface of any single piston at least nearly touches tangentially along generally radial lines the oval side surface of each of its four adjacent pistons so that any three pistons which are all adjacent to each other form a displacement chamber which varies in size as the pistons simultaneously rotate. Each piston is operably connected to a gear which is interconnected with the gears of the other pistons to regulate the relative positions of the pistons to ensure that all the pistons rotate with identical speed and direction with respect to the center of the machine. These gears may be located within or without the outer shell of the machine.
