ABSTRACT:
A device combines a fuel control valve in a hollow can and a carbon canister, which can be further combined with a fuel tank. The device has a first chamber for preventing draining fuel and a second chamber containing active carbon. The first chamber is formed with a gas tube which is connected to the fuel tank and a gas channel connected to the second chamber. The second chamber is formed with a gas return tube. As such, the device combining the fuel control valve and the carbon canister is constructed. The hollow can is assembled to a lateral wall of the fuel tank and the gas tube can be connect with the fuel tank to form an integral structure.
