ABSTRACT:
A power transmission includes a chambered housing having a horizontal axis with a rotatable crankshaft disposed therethrough and outwardly of the housing independently mounted upon a suitable support. A pair of diametrically opposed radial rods on said crankshaft pivotally mount a pair of pistons which on rotation of the crankshaft are yieldably biased outwardly. Cam rollers on said pistons bear against cam bore within said housing. Said bore includes a circular portion of maximum radius throughout 180.degree. approximately, merging into a cam surface gradually reduced to minimum dimension which merges into a circular pivotally adjustable segment portion of minimum radius throughout less than 90.degree.. The irregular cam bore provides for one piston traversing the maximum radius of said cam bore an increased leverage with respect to the other piston simultaneously traversing the cam portions and reduced radius portions of said bore.
