ABSTRACT:
A radial type, fluid pressure actuated (as distinguished from internal combustion) motor comprised of sets of opposed cylinders spaced in alinement and having double-acting pistons reciprocable therein, there being a crankshaft axially centered between the sets of opposed cylinders with the pistons of each set of said cylinders having a common connecting rod extending therebetween, each connecting rod being formed centrally of its ends with a Scotch yoke including a transverse, elongated slot, the yokes being disposed in adjacent side-by-side but right-angular intersecting relation, and the crankpin of the crankshaft extending in journaled but slidable relation through the slots of both yokes, and valves mechanically actuated from the yokes operative to feed fluid pressure to and exhaust the same from the cylinders in a predetermined cyclic order wherein the pistons of each set are simultaneously powered, in both directions of travel, and produce--by means of said connecting rods and yokes--continuous rotative motion of the crankshaft.
