ABSTRACT:
A rotary piston engine is shown which includes a housing (22) having a cylindrical working chamber with inlet (88) and exhaust (86) ports. First and second piston assemblies (30 and 32) each of which includes at least one pair of diametrically wedge-shaped pistons (30A and 30B, and 32A and 32B) are located in the working chamber. The piston assemblies rotate in the same direction at recurrently variable speeds so that one pair of diametrically opposite sub-chambers decreases in volume while the other pair increases in volume. In FIG. 1, four eccentric elliptical gear sets (60, 62, 64 and 66) interconnect coaxial piston shafts (38 and 36B). Compound eccentric elliptical gear sets (106 and 108) for interconnection of the piston shafts are shown in FIG. 7. Gear trains of large effective eccentricity are employed such that during the power phase of engine operation the trailing piston rotates only a small amount for efficient engine operation.
