Fuel Tank having Functions of Adjusting Press Produced by Fuel Volatilizing and Preventing Fuel Overflowing |
摘要 |
A fuel tank includes a canister and a fuel control valve arranged in an expanding room. The canister has two guiding pipes communicated respectively with an entrance of an engine and environment. The fuel control valve is communicated with the expanding room. A double-lane valve is arranged between the canister and the fuel control valve. The double-lane valve has an entrance communicated with the fuel control valve, an exit communicated with the canister, a first valve and a second valve arranged between the entrance and the exit. The second valve withstands a spring and is arranged on the first valve. The first valve can detect an expending press produced by volatilized fuel gas to control whether the fuel gas enter into the entrance of the engine. The second valve can detects a vacuum press of the fuel tank to control whether air enter into the fuel tank.
