Rotating cylinder valve engine

A rotatable cylinder valve engine characterized in that the engine comprises a piston disposed within a rotatable cylinder one end of which being formed with a bevel gearing that engages a drive gear, and a crankshaft assembly comprising a crankshaft rotatable about a first axis and being supported in a tubular sleeve having a central axis offset from the first axis, the arrangement being such that in use the clearance between the bevel gearing and the drive gear is adjustable by rotating the tubular support sleeve about the central axis of the tubular support sleeve.

A rotatable cylinder valve engine wherein the engine comprising a piston disposed within a rotatable cylinder and a cylinder jacket surrounding the rotatable cylinder, the cylinder jacket and rotatable cylinder being formed with gas fluid access ports extending therethrough, and the rotating cylinder being provided with an oil pump forming friction reducing and cooling means, the pump, in use, forcing oil over the rotating cylinder.

A rotatable cylinder valve engine comprising a piston disposed within a rotatable cylinder and defining therebetween a combustion chamber, wherein the rotatable cylinder comprises a tubular mid-section formed with a closed end and an open end, the rotatable cylinder valve engine further comprising a spring device disposed externally of the cylinder and adjacent the closed end of the rotatable cylinder for axially moving the cylinder relative to the piston to alter the compression ratio of the engine, wherein in use the spring device provides a self regulating compression adjustment.

A rotatable cylinder valve engine wherein the engine comprises a piston disposed within a rotatable cylinder formed with a gas access port, the arrangement being such that the longitudinal horizontal central axis of the inlet port that extends through the wall of the cylinder and does not intersect the longitudinal vertical central axis of the cylinder, and the volumetric center of the combustion chamber is offset from the central axis of the piston as specified by the second aspect of the present invention.

A rotatable cylinder valve engine wherein the engine comprises a piston disposed within a rotatable cylinder formed with a gas access port, the arrangement being such that when the piston is at the top dead-center of the stroke the base portion of the piston is adjacent the lowermost edge of the access port and a piston ring is disposed towards the bottom edge of the piston.

A rotatable cylinder valve engine comprising a piston disposed within a rotatable cylinder and a combustion chamber defined by the piston and the cylinder, wherein the arrangement of the rotatable cylinder and the combustion chamber is such that the volumetric center of the combustion chamber is offset from the central axis of the piston, wherein the offset combustion chamber is partly defined by a curved surface formed in the closed end of the cylinder, wherein the curved surface formed in the closed end of the cylinder extends from the gas access port in a direction towards the piston, and wherein a second curved surface is formed in the inner surface of the closed end of the cylinder, the second curved surface from the edge of the inner surface in a direction towards the other curved surface.
