Abstract
Rotary machines are disclosed that include, in one embodiment, a rotatable shaft defining a central axis A, the shaft having a first end and a second end. The shaft can have a first hub that defines a first gearbox disposed thereon with a plurality pivots. At least one contour also having pivots is connected to the first gearbox pivots by two linkages exterior to the first gearbox. The contour has a convex outer surface that cooperates with an inwardly facing curved surface of a housing to form a working volume. A gearbox mechanism including gears, crankshafts, bearings and connecting rods creates an oscillatory motion 2 times per revolution in the linkages such that the contour is forced to navigate about the arcuate cavity without contacting the cavity at a high rate of rotating speed.
