sifon

Sifon, or siphon in English, is a term used for devices and setups that move liquids from one place to another by gravity or by pressurized gas. The word can refer to several related concepts, most commonly a beverage dispenser, a culinary tool, or a plumbing component.

In the context of beverages, a soda siphon is a pressurized bottle designed to dispense carbonated water or flavored drinks. It typically consists of a bottle, a siphon tube, a valve head, and a nozzle. Carbon dioxide cartridges are used to pressurize the liquid, allowing it to be dispensed as a fizzy beverage. A related device, the cream siphon, uses nitrous oxide cartridges to whip cream or infuse flavors, and is also used in culinary applications. Both types rely on sealed vessels and gas pressure to force liquid through the nozzle.

In plumbing, a siphon refers to a U-shaped or S-shaped pipe (often called a P-trap) installed under sinks and drains. Its purpose is to retain a small amount of water to block the backflow of sewer gases while allowing liquids to drain away.

Sifons are manufactured in a range of materials, including metal and plastic, and require regular cleaning and maintenance. Safety considerations include proper handling of pressurized cartridges, avoiding exposure to heat, and ensuring seals and gaskets are intact to prevent leaks.

Overall, sifons are practical tools in kitchens, bars, and plumbing, linked by the common principle of using pressure or gravity to move liquids while maintaining separation from undesirable gases.
