Description

Background

Along with the development of economy, the requirements of people on automobiles are also higher and higher, and in order to meet the requirement of super-endurance, the design of double oil tanks is increased for part of automobile types. Since the fuel supply system of the vehicle further comprises a return line, i.e. a portion of the fuel is returned to the fuel tank after the fuel supplied from the fuel tank has entered the engine. Thus, the double fuel tank system must ensure that fuel flowing out of the working fuel tank flows back to the working fuel tank, and avoid the fuel flowing into the other fuel tank from exceeding the self-volume of the other fuel tank to cause the fuel leakage.

Usually, a three-way valve is added to ensure that fuel from the engine flows back to the working fuel tank. However, in order to ensure the convenience of operation, the three-way valve is generally controlled by an electrical signal, so that the three-way valve cannot realize a switching function once a circuit or a motor of the three-way valve fails. This results in the possibility of fuel flowing into other fuel tanks causing fuel leakage.

Therefore, in the prior art, the technical problem that fuel cannot flow back to a specified fuel tank and fuel leaks due to the failure of an electric valve circuit exists.
