Oscillating piston engine

Patent ·
OSTI ID:6349825
In an internal combustion engine comprising: (a) a rotating annular cylinder, (b) a plurality of pairs of oscillating pistons in the cylinder, (c) means to oscillate the pistons so as to alternately move adjacent pistons apart from one another and toward one another for the respective strokes of the internal combustion engine, (d) intake ports, exhaust ports and ignition means on the rotating annular cylinder for registry with the respective spaces between the adjacent pistons according to the firing order and cycle of the engine, (e) a power take-off shaft in the engine, (f) means to convert the oscillating of the pistons into rotation of the power take-off shaft, (g) transmitting means between the power take-off shaft and the cylinder to rotate the annular cylinder in a predetermined ratio to the oscillation of the pistons for registering the intake ports, exhaust ports and ignition means with the respective spaces between the oscillating pistons in a predetermined sequence, (h) the ratio between the rotation of the shaft and the resulting angular oscillation of the pistons with respect to the rotating annular cylinder is one oscillation of each piston for each quarter of one revolution of the cylinder, (i) the inner periphery of the cylinder being of circular cross-section and the pistons being also of circular cross section, and piston rings on the pistons being in contact with the inner circular periphery of the cylinder, (j) the means to convert the piston oscillation into rotation including concentric tubes journalled concentrically with the rotating cylinder, (k) connecting means between the tubes and the power take-off shaft for converting oscillation of the tubes into rotation of the shaft.
