Abstract
The crankless sinusoidal engine has at least one cylinder, one standard piston and head with combustion chamber and inlet and exhaust valves. A main shaft with one flywheel with incorporated sinusoidal track, Connection between the piston and the sinusoidal track consists of four items; to wit, one connecting rod, one bearing trolley and two segmented rollers, said rollers being in constant contact with said sinusoidal track, one bearing on each side thereof. The bearing trolley sliding on guide pins anchored in opposite ends of cast (alternatively fabricated) housing, said guide pins positioned parallel to the main shaft. Pressure from the piston forces the segmented rollers against the sinusoidal track, causing rotation.
Claims8
A crankless sinusoidal engine comprising at least one cylinder, complete with head and inlet and exhaust poppet valves. A main shaft mounted parallel to the cylinder, one flywheel with incorporated sinusoidal track, mounted near the center of the main shaft, one connecting rod attached to the piston at one end and to a bearing trolley at the other by means of a wrist pin, said bearing trolley having two segmented rollers spaced so as to fit snugly, one against each side of the sinusoidal track. The bearing trolley is mounted on two guide pins so that it will slide parallel to the main shaft and cylinder. The guide pins are rigidly mounted in and between the front and back ends of the housing. Force from the piston through the connecting rod, bearing trolley, and segmented bearings against the sinusoidal track cause the track, flywheel, and main shaft to rotate, all enclosed in a housing.
