piston rods
n. (plural of piston rod English)
Usage examples of "piston rods".
Like an airborne mote within the eerily lit bowels of that colossal imaginary mechanism, he drifted past massive walls and interconnected columns of whirling drive shafts, rattling drive chains, myriad thrusting piston rods joined by sliding blocks to connecting rods that were in turn joined by crank wrists to well-greased cranks that turned flywheels of all dimensions.
The piston transmits that force to the piston rods, cranks, and other elements.
