What is the name of the cylinder that can be inflated

Cylinders that can be inflated are often referred to as air cylinders. This is because air cylinders are mainly used to store gases or liquids and perform the function of inflation by increasing the internal pressure. Cylinders are usually made of materials that are highly resistant to pressure, such as metal or plastic, to ensure that they can withstand high pressures. By filling the cylinder with gas or liquid and closing it, the gas or liquid can be stored and compressed inside. When the stored gases or liquids are needed, they can be released through an appropriate valve or port.

It's worth noting that an air cylinder is not only used for inflation, it can also be used for liquid storage and pressure transfer. For example, air cartridges are used in the brake systems of automobiles to store and transfer brake fluid. In this case, the air cylinder is known as a brake cylinder.

In addition, with the continuous development of science and technology, air cylinders have more application areas, such as industrial production, medical equipment, aerospace and so on. Thus, air cylinder plays an important role in various fields as a device used to store and transfer gases or liquids.
