ABSTRACT:
A rotary engine includes separate chambers for receiving pressurized air and fuel. An air chamber stories pressurized air that is routed into a combustion chamber to be mixed with fuel for combustion to drive a piston. The combustion chamber is forced open during a firing cycle to allow expanding gases into a piston chamber. A valve door serves as a base against which the expanding gases react to force a piston in a forward direction. The piston is coupled to a crank shaft which may in turn be coupled to a transmission or other power drive device to harness energy created by the turning crankshaft. A lifter includes a gear that rotates to raise and lower the valve door such that it moves towards and away from the crankshaft to optimize the amount of energy that is directed against the piston. Through series of multiplier gears, the amount of movement necessary to lift the door is minimal.
