Abstract
An apparatus is provided for controlling flow of fuel vapor and liquid fuel through an aperture in a fuel tank. The apparatus comprises a housing mounted in the aperature, a float valve, a ball, and a mechanism for supporting the ball. The housing is formed to include an outlet, and the float valve is movable in the housing between a closed position blocking flow of fuel vapor and liquid fuel through the outlet and an open position allowing flow of fuel vapor through the outlet. The float valve is formed to include a float chamber and the ball is positioned in the float chamber. The mechanism for supporting the ball is movable relative to the housing. The support mechanism is configured to support the ball in the float chamber so that the ball is able to move in the float chamber in response to movement of the fuel tank to urge the float valve to its closed position.
