Abstract
Fuel reservoir apparatus can maintain and control pressure within a fuel tank at a low level during an operation of an engine, and also can prevent excessive refuelling. The fuel reservoir apparatus includes the fuel tank, a canister, a fuel vapor passage, a positive pressure valve, a solenoid valve, and a closure valve. The fuel tank stores liquid fuel to be supplied to the engine of an automobile. The canister can adsorb the fuel vapor. The fuel vapor passage connects the fuel tank to the canister. The positive pressure valve is provided in the fuel vapor passage for controlling pressure within the fuel tank, using a spring force. The solenoid valve is provided in the fuel vapor passage and adapted for opening during the operation of the engine to flow the fuel vapor towards the canister. The closure valve is provided in the fuel vapor passage for closing the fuel vapor passage when fuel is supplied to the fuel tank.
