Abstract
A device combining a two-way valve and a carbon canister includes a hollow can, which can be further combined with a fuel tank. The device has a first chamber for regulating inner pressure of the fuel tank and a second chamber containing active carbon. The first chamber is installed with a gas tube which is connected to the fuel tank and a gas channel connected to the second chamber. The second chamber is installed with a gas return tube so as to form the device combining the two-way valve and the carbon canister. The hollow can is assembled to a lateral wall of the fuel tank and the gas tube can be embedded into the fuel tank to form an integral structure.
