Abstract
A rotary internal combustion engine comprising a cylinder in a stator sealed between parallel end plates, a power shaft concentric with the cylinder bore and journaled in bearings in the end walls, an annular eccentric rotor fitted onto the shaft, and an annular piston concentric with and fitted over the rotor making sliding sealing engagement with both end plates. An abutment centered preferably between 10:00 and 10:30 o'clock on the stator seals the space between the cylinder and piston from endplate to endplate and forms the counterclockwise end of a combustion-expansion chamber. A second abutment, centered preferably between 1:30 and 2:00 o'clock, seals the space between the cylinder and piston from endplate to endplate and forms the clockwise end of the combustion-expansion chamber. The combustion chamber centered at 12:00 o'clock comprises a shallow arcuate cavity adjacent the path of the piston and opening into the cylinder. Fuel injection means for the invention engine may be mounted on an endplate in advance of the first abutment or positioned on the end wall at approximately 12:00 o'clock to inject forward directly into the combustion chamber. Various means for admitting …
