id0116q2122900
Purpose, Function
• The rollover valve prevents fuel flow into the evaporative gas passage during sudden cornering or vehicle rollover.
Construction
• The rollover valve is located inside the fuel tank.
Fuel tank type A
Fuel tank type B
• The rollover valve consists of a float (valve), O-ring, and spring.
Operation
• Because the float (valve) is normally open, evaporative gas in the fuel tank is introduced to the charcoal canister.
• When the float (valve) is immersed in the fuel during sudden cornering or vehicle rollover, the passage is blocked by spring force and the ascending force of the float (valve).
