Abstract

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.
