Abstract
The float has an elastomeric valve disk with an annular bead rim caged for limited lost motion movement on the top of the float. A rigid backing plate for the valve disk is pivoted on a curved surface on the top of the float to ensure self-alignment of the valve disk on the vent port seat when the float is moved upward by the rising liquid level for closing the vent during refueling. As fuel is used from the tank, the float drops and the angled top of the cage contacts the bead rim on the valve disk and effects a peel-away re-opening of the valve.
