<p>PURPOSE:To keep and control the inner pressure of a tank at a low pressure when an engine is driven, and prevent overcharge of oil during oil feeding. CONSTITUTION:A fuel storage device is provided with a fuel tank 1, a canister 19, a path 20 for fuel vapor, a positive pressure valve 31, a solenoid valve 44, and a closing valve 49. The fuel tank 1 stores a liquid fuel F for supplying it to an automobile engine E. The canister 19 can absorb the fuel vapor V. The path 20 for the fuel vapor connects the fuel tank 1 to the canister 19. The positive pressure valve 31 is arranged in the path 20 for the fuel vapor to adjust the pressure in the fuel tank 1 by use of a spring energizing force. The solenoid valve 44 is arranged in the path 20 for the fuel vapor to open so as to run off the fuel vapor V to the canister 19 side on driving the engine. The closing valve 49 is arranged in the path 20 for the fuel vapor to shut the path 20 on feeding fuel into the fuel tank 1.</p> |
