Purpose, function
The check valve maintain the pressure in the fuel tank at constant pressure.
Construction
The check valve is installed to the side of the charcoal canister.

Mainly consists of valve, umbrella, and spring.

Operation
The valve moves in response to the difference in air pressure between the fuel tank side and the atmospheric side, thereby changing the path of airflow.
When the pressure in the fuel tank becomes negative due to fuel consumption or other factors, the path opens, drawing atmospheric air into the fuel tank.
