ROTARY INTERNAL COMBUSTION ENGINE

摘要

A two stage rotary internal combustion engine consists of a compression chamber and an expansion chamber having respectively an inlet and an exhaust port. A rotor is arranged in each chamber to rotate therein in timed relation to one another. At least one vane is associated with each chamber, and each chamber, rotor and vane therein being so shaped and arranged to define a sealed working chamber which varies in volume as the rotor rotates. A transfer port communicates the compression and expansion chambers and means are provided to selectively open and close the transfer port in timed relation with the rotation of the rotors.
