The compressor is a machine/tool to compress air or gas. In general, it usually sucks air, which is a mixture of several gases with a composition of 78% Nitrogen, 21% Oxygen, and 1% mixture of Argon, Carbon Dioxide, Water Vapor, Oil, and others. But some compressors suck air/gas with a pressure higher than atmospheric pressure and are usually called boosters. On the other hand, some compressors suck in air/gas with a lower pressure than atmospheric pressure and are usually called vacuum pumps. Its function is to increase gas or air pressure. It can be done by volume reduction. When the volume is reduced, the pressure increases.

Thanks to the compression process, the air gains the higher pressure compared to the ambient air pressure (1atm). In everyday life, we often take advantage of compressed air either directly or indirectly. For example, compressed air is used to fill car or motorcycle tires, compressed air to clean dirty engine parts in workshops, and other benefits that are often encountered daily.
In industry, the use of compressors is very important, either as a producer of compressed air or as a unit of machines. Compressors are widely used for pneumatic engines, while those that are integrated with the engine are gas turbines, refrigeration engines, and others.
By taking the example of a simple compressor, namely a bicycle or car tire pump. If the piston of the pump is pulled up, the pressure under the cylinder will drop to below atmospheric pressure so that air will enter through the slack inlet valve opening. The valve is made of flexible leather, can tighten and loosen, and is attached to the piston. After the air enters the pump then the piston drops down and presses the air, so the volume becomes small.
The pressure continues to rise until it exceeds the pressure inside the tire so that compressed air can enter the tire through the valve. Because it is filled with compressed air continuously, the pressure inside the tires increases. So it is clear from this example, the compression process occurs because the volume change in the air is smaller than the initial condition.
