Abstract:
A rotary combustion machine having:a toroidal cylinder;a rotor mounted on a shaft for rotation about an axis of said cylinder;at least two pistons mounted on the rotor, the pistons having a cross-sectional area substantially equal to the cross-sectional shape of the cylinder, the rotor and pistons being arranged so that as the rotor rotates the pistons sweep the internal volume of the cylinder;a valve mechanism comprising two parallel contra-rotating plates, each with a cut-out at its periphery, the plates being arranged so that their plane of rotation intersects the cylinder at one point around the cylinder circumference;a compressed gas outlet leading from the cylinder on one side of the valve mechanism;a compressed gas chamber for receiving gas from the outlet;a combustion passage leading into the cylinder on the opposite side of the valve mechanism;a valve, for opening and closing the combustion passage independently of the valve mechanism;means for igniting a combustible gas mixture in the combustion passage; anda working fluid inlet to and an exhaust outlet from the cylinder to, respectively, admit fluid to and exhaust fluid from opposite sides of the valve mechanism, the working fluid inlet and exhaust outlet being in positions which, referred to the diameter of the toroidal cylinder, are substantially diametrically opposite to the valve mechanism.
