ABSTRACT:
The present invention relates to a solenoid valve disposed over a fuel tank and incorporating a liquid surface detecting valve for detecting the liquid surface in a fuel tank. The solenoid valve comprises a plunger and an adhesion preventive pin wherein the adhesion preventive pin is lowered in the direction of the liquid surface detecting valve at the time of opening of the solenoid valve and the same pin pushes the liquid surface detecting valve downward at the time when the liquid surface detecting valve is attached and adhered to a valve seat thereof, whereby the liquid surface detecting valve is open with assurance.
