Rollover Valve: Description and Operation
Roll-over Shut-off Valve
The roll-over shut-off valve closes only if the car rolls over, preventing fuel leaks.
There is a line connecting the valve with the emission canister. Expansion vapors in the tank are let out through the valve and the emission canister.
