Air gets into an air compressor through an air inlet valve, which is often protected by an air filter.
Here's a breakdown of the process:
-
Air Inlet Valve: This valve is designed to allow air to enter the compression chamber but prevent it from escaping back out. It's a one-way valve.
-
Air Filter: Most air compressors have an air filter located before the inlet valve. Its primary job is to remove contaminants like dust, dirt, and debris from the air before it enters the compressor. This protects the internal components of the compressor from damage and ensures cleaner compressed air output.
-
The Compression Process: As the compressor piston moves (or other compression mechanisms like rotary screws operate), it creates a vacuum or negative pressure within the cylinder or compression chamber. This pressure difference pulls air in through the open inlet valve.
-
Valve Closure: Once the cylinder is full of air (or the compression process reaches a certain point), the inlet valve closes, sealing the air within the chamber.
In summary, air is drawn into an air compressor due to the pressure difference created by the compressor's internal mechanism, entering through an air inlet valve after passing through an air filter.
