pístav

Pístav is a term originating from Czech, commonly translated as "piston" in English. It refers to a sliding component that moves back and forth within a cylinder. This reciprocating motion is fundamental to the operation of various types of engines and mechanical devices.

In internal combustion engines, the piston is crucial for converting the chemical energy of fuel into mechanical energy. It is driven downwards by the expanding gases produced during combustion, thus turning the crankshaft. In steam engines, a piston is propelled by steam pressure, also generating rotational motion.

Beyond engines, pistons are also found in hydraulic and pneumatic systems. In these applications, they are used to transmit force or pressure through a fluid. For example, hydraulic cylinders use pistons to lift heavy loads, while pneumatic cylinders utilize compressed air. The precise design and material of a piston vary depending on its intended use, considering factors such as temperature, pressure, and the medium it interacts with.
