Claims

[Scope of utility model registration request]

It has a main tank and a sub-tank that communicate with each other through a conduit, and the conduit is provided with a solenoid valve for cutting off the flow of fuel between both tanks, and at least one of the tanks is provided with a liquid level detector. In a vehicle fuel tank, a solenoid valve is provided in which the solenoid valve is closed to block the fuel flow between the two tanks when the fuel level in the tank exceeds a predetermined value. A relay circuit is provided to control the supply of excitation current to the solenoid valve, and the relay circuit is provided with a time constant circuit that supplies an excitation signal to the solenoid valve until the full tank detection signal of the liquid level detector continues for a certain period of time. A vehicle fuel tank characterized by preventing chattering of a solenoid valve.
