Abstract

A ROTARY INTERNAL COMBUSTION ENGINE OF THE TYPE HAVING PISTONS (70) MOUNTED FOR RECIPROCATORY MOVEMENT IN RESPECTIVE CYLINDERS (75) WHICH ARE ARRANGED IN EQUALLY-SPACED RELATIONSHIP AROUND A LONGITUDINAL AXIS OF ROTATION, SAID AXIS BEING THE AXIS OF ROTATION OF AN OUTPUT SHAFT (55) PASSING ROTATABLY AND SEALABLY THROUGH APERTURES (62) OF RESPECTIVE FIRST AND SECOND END PLATES (54) OF A HOUSING (50) WITHIN WHICH THE PISTONS AND CYLINDERS MOVE AS PART OF A ROTATABLE ROTOR ASSEMBLY (78) SECURED TO SAID OUTPUT SHAFT, WHILE THE PISTONS ARE SIMULTANEOUSLY MOVABLE RECIPROCABLY IN THE CYLINDERS, CAM FOLLOWER MEANS (71) BEING ASSOCIATED WITH EACH PISTON AND ADAPTED TO COACT WITH UNDULATING CAM TRACK MEANS (65) AROUND THE HOUSING. CYCLICAL COMBUSTION OF FUEL IN THE CYLINDERS (75) IMPARTS RECIPROCATION TO THE PISTONS (70) WITH RESULTANT THRUST AGAINST THE CAM TRACK MEANS (65) SO AS TO CAUSE ROTATION OF THE ROTOR ASSEMBLY (78) AND OUTPUT SHAFT (55). THE PISTONS INCLUDE TWO SETS THEREOF EACH HAVING AT LEAST TWO PISTONS, THE PISTONS OF EACH SET BEING AT OPPOSITE SIDES OF THE AXIS OF ROTATION OF THE ROTOR ASSEMBLY (78) AND OUTPUT SHAFT AND ARE INTERCONNECTED BY PISTON-CONNECTION MEANS (67, 79) SO THAT THE PISTONS OF EACH SET MOVE IN UNISON, THE PARTS BEING SO MADE AND ARRANGED THAT THE PISTON CAM FOLLOWER MEANS (71) COACT WITH THE CAM TRACK MEANS (65) IN A MANNER ENSURING THAT MOVEMENT OF EITHER SET OF PISTONS IN THEIR CYLINDERS IS IN THE DIRECTION OPPOSITE TO THE DIRECTION OF MOVEMENT OF THE OTHER SET OF PISTONS.
