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.

Tank venting control system

An apparatus is provided that includes a valve container with a vapor inlet adapted for communicating with an interior region of the fuel tank and a vapor outlet, a baffle including an upper end coupled to the vapor inlet, an open lower end spaced-apart from the upper end, and a skirt extending between the upper and lower ends, and a float valve disposed in the valve container and movable between an opened position allowing flow of fuel vapor through the vapor outlet and a closed position preventing flow of fuel vapor through the vapor outlet. The skirt of the baffle includes at least one slot therethrough and the float valve is positioned to lie between the vapor inlet and the slot of the baffle when in both the opened and closed positions.

Liquid fuel baffle for vent apparatus

An apparatus includes a valve container and a valve member. The valve container is formed to include an inlet in fluid communication with a fuel tank, an outlet, a side wall extending between the inlet and outlet, and a chamber in fluid communication with the inlet and the outlet. The valve member is disposed in the chamber and includes a central post and wing segments positioned to lie in a spaced apart relationship about the post. The wing segments are formed to define flow passages therethrough that are sized to permit the flow of fuel vapor therethrough and to momentarily block the flow of liquid fuel therethrough.
