ABSTRACT:
Disclosed is a valve for preventing fuel from flowing from the vent of an automobile fuel tank comprising a valve compartment and a float vertically movable in the valve compartment, said float having a longitudinal hole communicating with vent holes made in the ceiling of the flat body or in the seat of a head fixed to the ceiling of the float body, thereby allowing the vapor of the fuel to ascend through the longitudinal hole of the float body and fill the upper space defined by the inner surface of the valve compartment and the outer surface of the head of the float thus to maintain the same pressure in the upper space as in the fuel tank at all times. Thus, the float can descend immediately when the automobile returns from an inclined position to the horizontal position.
