When the compressor is working, the higher the pressure, the larger or the smaller the flow rate.

When the compressor is working, the higher the pressure, the smaller the flow rate.

Compressor is like a "pressure pump", its core task is to "squeeze" low-pressure gas into high-pressure gas. When the internal pressure of the compressor rises, the gap between the gas molecules will be compressed smaller and smaller, just like pressing a spring, the spring will shorten.

At the same time, the channels and spaces inside the compressor are fixed. When the gas is pressed more tightly, just like a water pipe is pinched, the amount of gas that can flow through per unit time will be reduced. Therefore, when the pressure rises, the flow rate of the compressor tends to decrease.
