ABSTRACT:
A rotary engine with complemental cylindrical rotors facing each other and rotatable about a common shaft. Each rotor has an annular recess with a pair of diametrically opposed pistons mounted therein, the pistons having their outer ends projecting beyond the recess and being oscillatably receivable in the annular recess of the adjacent rotor. Novel means is used for causing the four pistons to form four chambers between pairs of adjacent pistons, the pistons while rotating about the shaft being caused to oscillate with respect to each other so that for each revolution of the shaft, each of the four chambers will be successively enlarged for the "intake stroke" to receive a combustible gas, then contracted for the "compression stroke" in compressing the gas, then the compressed gas will be ignited for the "power stroke" causing the chamber to be enlarged and the power from the exploding gas being directed against the walls of the pair of pistons for rotating the shaft and finally the contracting of the chamber for exhausting the burnt gases.
