hivattyú

Hivattyú is a Hungarian term that translates to "piston" in English. It refers to a component, typically cylindrical, that moves back and forth within a cylinder. This reciprocating motion is fundamental to the operation of many mechanical devices, most notably internal combustion engines and pumps.

In an internal combustion engine, the hivattyú is crucial for converting the energy released from the combustion of fuel into mechanical work. As the fuel-air mixture ignites, the expanding gases push the hivattyú downwards, which in turn rotates a crankshaft. This rotational motion is then transmitted to power the vehicle or machinery. The hivattyú is sealed within the cylinder by piston rings to prevent leakage of gases.

In pumps, the hivattyú's movement creates a pressure differential that draws fluid into the cylinder and then expels it. This principle is utilized in various types of pumps, including water pumps and hydraulic pumps. The size, material, and design of the hivattyú are critical factors determining the performance, efficiency, and durability of the device in which it is used.
