ABSTRACT:
A rotary engine includes a pair of rotors each supporting opposed toroidal section pistons rotatably disposed within a crank case defining a toroidal combustion chamber. The piston rotors define pluralities of curved slots which receive interconnecting coupling pins. A drive cam cooperates with the drive pins and a slotted pin guide is captivated between the drive cam and one of the slotted piston rotors. The cooperation of the pin guide, cam and slotted rotors provides the required piston motion and power coupling for use as a rotary engine for rotary pump or compressor.
