ABSTRACT:
A high efficiency, low cost fluid pressure engine. This engine converts reciprocating piston motion to rotary output in a novel manner. The engine comprises at least two parallel pistons adapted to reciprocate in cylinders within an engine block closed by upper and lower heads. Each piston is rigidly secured to a piston rod located along the cylinder centerline and extending through substantially fluid tight packing in the lower head. The lower end of each piston rod is flexibly connected to a first connecting means which also includes an opening surrounding a first crank pin. A pair of reciprocating valve means, located within said engine block, are adapted to selectively introduce and exhaust the engine drive fluid into and out of the cylinder above and below the pistons. Valve push rods secured to said valve means are connected to a second connecting means which also has an opening surrounding a second crank pin. Swinging link means are provided interconnecting each of said first and second connecting means and the engine housing to constrain the movement of the piston rods and valve push rods to substantially linear motion. The first and second crank pins are mounted on a crank plate offset from an output drive shaft so that as steam or another fluid drives the pistons, linear motion is converted to rotary output motion. The crank assembly, which converts piston reciprocating motion to rotary output is made up of several simple parts bolted together to provide a complex assembly including both crank pins, means for adjusting valve timing, balance weights, etc.
