Abstract
A fuel vapor control valve is provided for controlling the flow of fuel vapor and liquid fuel through an aperture in a fuel tank. The fuel vapor control valve includes a housing mounted in the aperture. The housing is formed to include an inlet in fluid communication with the fuel tank and an outlet. A valve is movable in the housing between a blocking position blocking flow of fuel vapor between the inlet and the outlet and a venting position allowing flow of fuel vapor between the inlet and the outlet. The fuel vapor control valve also includes a spring for biasing the valve toward its blocking position and a mechanism for using fuel vapor from the fuel tank to move the valve toward its venting position. A ball is movably positioned in the venting control chamber to selectively interrupt the fluid communication between the inlet and the outlet.
