Oil is forces into one part of the cylinder, moving the piston in the opposite direction, imparting force to a shaft that is part of the piston. Note that a cylinder without a piston, or a piston without a cylinder, is not considered a hydraulic cylinder. Both parts are essential to its identity.")
