  • Compressed fluid motor
    Patent number: 8640450
    Abstract: A compressed fluid motor has a plurality of cylinders with a piston and a piston rod. A main bearing is concentric with a crankpin and coupled to a shaft. Compressed fluid on the piston pushes on the main bearing via its corresponding piston rod. Bearing guide plates hold the one or more piston rod in place on the main bearing. A timing and control mechanism controls flow of compressible fluid to press on the piston and turn the shaft to perform work.
