<p>PURPOSE: A roll over valve for a vehicle is provided to simplify the structure of a roll over valve and to exactly input fuel. CONSTITUTION: When a fuel surface is low inside a fuel tank, gas evaporated from the fuel passes a first and a second flue tube(4,7) through an inlet tube(1) and is collected to a canister through an outlet tube(3) installed in a ball case(10). The fuel is smoothly input in the fuel tank while the fuel the gas inside the fuel tank is discharged through the inlet tube(1) and the outlet tube(3). When it is close to the full state of fuel, the oil surface reaches around the inlet tube. Further, when the oil surface reaches over the height of the inlet tube, the inlet tube is stuck, and the gas is not discharged so that the input of fuel is stopped.</p> |
