Abstract
An apparatus is provided for controlling discharge of fuel vapor from within a vehicle fuel tank. The apparatus includes a valve container with an inlet, an outlet, and a chamber, a valve member formed for movement between an open position allowing fuel vapor flow through outlet and a closed position blocking fuel vapor flow through outlet, and a secondary float valve disposed between inlet and valve member. The valve member includes a central post and wing segments defining flow passages sized to permit fuel vapor flow therethrough and to block momentarily liquid fuel flow therethrough. The secondary float valve moves between an open position allowing fuel vapor flow to the wing segments and a closed position blocking liquid fuel flow to the wing segments.
