how do they working?
could you introduce me some websites where i can get more information about compressor?

There are actually several kinds of air compressors. Reciprocating compressors use a piston (or multiple pistons) in cylinder(s) with valves timed to control when the air goes in and out of the cylinder. These compressors are widely used in manufacturing and/or maintenance shops. They are also used in the little compressors where you get air in your tires at the gas station.
Another type of compressor is a rotary vane (or sliding vane) compressor. These are a little tougher to describe without a picture. Basically they consist of a rotating sleeve that spins off-center from the cylinder in which it is housed. The sleeve has slots in it with spring-loaded vanes which seal against the outer cylinder. As the sleeve rotates, the vanes slide in and out of the sleeve, varying the volume between the sleev, two vanes, and the cylinder. This changing volume generates the airflow and compression. They are commonly used on small airplanes (think 4 seat, single engine Cessnas) to create a vacuum that powers a couple of the pilot's flight instruments, though some create pressure to drive the instruments. The same pump can create pressure or a vacuum simply by connecting a hose to the outlet or inlet.
Modern day jet engines use a compressor known as an axial flow compressor. They are very similar to a simple fan. Imagine stacking up several fans in a duct, one after the other. You could actually generate a significant pressure difference between the inlet to the first fan and the outlet of the last fan.
And the final air compressor I'll mention is used in modern day turbo-chargers and many old (30-40 years ago) jet engines. It's the centrifugal flow compressor. In a centrifugal flow compressor, air flows into the center of the compressor and gets flung outward by centrifugal force.
I'm sure there are other types of air compressors out there, but these are probably the most common ones out there today.

If you are speaking of air compressors, there are 2 types single stage or dual stage compressors.
A single stage takes atmospheric pressure air +/1 14.5 PSI and uses some type of pumping mechanism, either a gear pump or more commonly a piston to compress the air.
A dual stage then takes the air from the single stage pump and compresses it again to obtain higher pressures and more consistent volume.

Two general types of air comperssors
a.) Reciprocating
b) Rotary
Stages referrs to the number of compression steps it takes for atmospheric air pressure to be pumped up to the operating air pressure.
