ROLLOVER VALVE CONSTRUCTION/OPERATION [MZR 1.6]
id011607103000
Construction
• The rollover valve is built into the fuel tank.
• 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).
