ABSTRACT:
A float valve for use in a fuel tank, having a float for regulating air flow out of an air outflow channel provided in an upper portion of the fuel tank. An air flow deflecting portion provided on the float prevents the float from being lifted as air and fuel vapors displaced when the fuel tank is filled-up escape the tank. When the fuel level in the tank rises to a filled-up position, the outflow of air is stopped by the float.
