Granted: 2003-08-19
Abstract: A fuel reservoir for storing a fuel, provided with a wall which divides the inner space of the reservoir into a fuel chamber and an air chamber and is variable in shape depending upon the amount of fuel in the fuel chamber, a discharge passage opened to a space formed above a fuel liquid surface in the fuel chamber, and a shut-off valve for normally shutting off the discharge passage. When the shut-off valve is opened, a gas is discharged from the space through the discharge passage. If the amount of the gas is greater than a predetermined amount, the shut-off valve is opened so as to discharge the gas out of the space. On the other hand, if the amount of the gas is less than the predetermined amount, the shut-off valve is closed to stop discharge of the gas.
