Abstract
Abstract A rotary power device comprised generally of a toroidal housing providing a toroidal cylinder chamber, a drive shaft extending through the central hole in the housing which is inclined at a predetermined angle thereto, at least one pair of rotors, rotatable within the central hole of the housing about the shaft, each connecting to at least one piston, slidably disposed in the toroidal cylinder, and links connecting between the drive shaft and each of said rotors. The toroidal cylinder provides an air or combustible mixture intake chamber, a compression chamber, a fuel injection chamber and a firing chamber and an exhaust chamber.
