ABSTRACT:
A vapor vent valve for a fuel tank that includes a vapor outlet that connects an interior of the fuel tank with an exterior of the fuel tank. The vent valve also includes a fill cup that has an opening at one end and a sidewall that extends from the open end. A shell defines an interior space and is disposed partially in the fill cup. The shell includes a sidewall that has an opening and an upper edge. A flow passage is defined between the fill cup's sidewall and the shell sidewall to allow fluid which flows into the opening of the fill cup to enter the interior space through the opening in the sidewall of the shell. A float is received in the interior space and is responsive to the level of liquid fuel in the interior space. A closure pivotally carried by the shell is movable to a closed position to prevent fluid flow through the vapor outlet. The closure is also movable to an open position which allows fuel vapor to exit the fuel tank. The closure includes a carrier plate that has an elastomeric layer attached to the carrier plate. The elastomeric layer includes a portion that is attached to the float for actuating the closure to the open and closed positions.
