shtok_215x260.pngRod – is the core of round section connecting the piston to a slider (cross-head) in piston cars (pumps, compressors, steam engines, some internal combustion engines, etc.) or in hydraulic and pneumatic mechanisms of the drive of a headway. The rod is applied when both cavities of the cylinder are used (on that and other party of the piston). 

When using one cavity of the cylinder in the piston car the rod usually is absent and the rod joins immediately the piston. Not passing, or unilateral, the rod settles down on one party of the piston and is passed through one cover of the cylinder, the passing rod is passed through both covers of the cylinder for the purpose of the best direction of the heavy piston (in steam-engines) or connections of the second cylinder (in compressors). In headway hydraulic actuators the cylinder sometimes fastens to the relative frame part of the car (a table of the machine), and a rod — to a bed. Then through a rod oil in a cylinder cavity is brought. Diameter of a rod usually is defined by its durability, a rigidity and stability, but in a headway hydraulic actuator — sometimes the demanded ratio of speeds of forward and return motion at constant pumping capacity.
