Russell, R L

An internal combustion four cycle rotary engine is described comprising: a generally cylindrical having one or more accurately spaced cylinders, each carrying a piston therein extending radially of a central rotational axis of the rotor; stationary bearings support shaft means disposed coaxially of the rotor, unitary combustion chamber means carrying main bearing means for rotatably supporting the same on the shaft means and providing one or more individual combustion chambers, each independently communicating with one of the cylinders; the chamber means being mounted concentrically of the rotor and rotatably moveable therewith about the shaft means; cam means comprising a pair of registeringly aligned, axially spaced, continuously curvilinear cam track means which are formed radially assymmetrical about a central axis coincident with the rotational axis of the rotor; the pair of cam track means being located axially outwardly of the cylinders in parallel planes lying formal to the rotational axis and adjacent opposite axial ends of the rotor; cam rider assembly means, each having follower means engaged with the track means for following the contour thereof; and means coupling a rider assembly means to the piston in each cylinder whereby to effect reciprocal strokes of each piston coaxially of its associated cylinder and radially of the rotor in response to the movements of the follower means along the track means; the track means being constructed and arranged to produce distinctly dissimilar movements of the pistons, to produce strokes of unequal duration and length during the respective intake, compression, combustion and exhaust strokes thereof.
