ROLLOVER VALVE
NOTE
See Figure 4-6. When the vehicle is upright the check ball
holds the post to one side allowing hydrocarbon vapors to be
released into the atmosphere or into a charcoal canister (Cal-
ifornia). When the vehicle is tipped, the check ball moves
away from the post, which is spring loaded, allowing the post
to seal the opening preventing loss of gasoline through the
vent tube.
