ABSTRACT:
A rotary internal combustion engine including a rotatable drive shaft, a first rotatable disc secured to and rotatable with the drive shaft, a second disc rotatably disposed through a geared connection about the drive shaft for opposite rotation relative to the first disc; and a fixed partition rotatably receiving the drive shaft and being sandwiched between the first and second rotatable discs. Each of the first and second rotatable discs are provided with annular channels facing, and closed by the partition. Dams are provided on the partition faces to close and divide the annular channels in each of the rotatable discs into a pair of arcuate chambers. A pair of vanes are retractably disposed in spaced relationship within each annular chamber, dividing the arcuate chambers into separate intake/compression and combustion/exhaust chambers. An air/fuel mixture is supplied to each disc, compressed therein by the intake/compression chamber, and transferred through the partition, to the combustion/exhaust chamber in the other disc for combustion. The combustion gases expand and act against the respective vanes to drive both discs and provide rotary output to the drive shaft.
