A piston is mainly used in internal combustion engines to transfer force in the cylinder to the crankshaft via a connecting rod upon the pressure of the expanding combustion gases. However, they are also used in pumps, and their function there is reversed, as the force is transferred from the crankshaft to the piston for the purpose of compressing (or ejecting the fluid in the cylinder). In some engines, like two-stroke engines, the piston also acts as a valve by covering and uncovering ports in the cylinder wall.
