pistón

Pistón is a Spanish word that translates to "piston" in English. A piston is a fundamental component found in many mechanical devices, most notably internal combustion engines and pumps. It is a sliding component that moves back and forth within a cylinder. In an engine, the piston is propelled by the expanding gases from the combustion of fuel and air, transmitting this force to a crankshaft to generate rotational motion. In a pump, the piston's movement creates pressure differentials, drawing fluid in and expelling it.

The primary function of a piston is to convert pressure into force or vice versa. It typically forms a seal against the cylinder walls, often with the aid of piston rings, to prevent leakage and ensure efficient operation. The design and material of a piston vary depending on its application, considering factors such as temperature, pressure, and speed. Common materials include aluminum alloys and cast iron. The reciprocating motion of the piston is a key element in many thermodynamic cycles and fluid transfer systems.
