Abstract
A tank venting apparatus or a fill-limit and tank ventilation valve is disclosed for use with a fuel tank. The valve has a housing which contains a first valve assembly, second valve assembly, third valve assembly and fourth valve assembly. The first valve assembly primarily communicates with the fuel tank. The fourth valve assembly communicates with a vapor recover canister and a filler neck to the tank. The first valve assembly also communicates with the third valve assembly and the second valve assembly. The second valve assembly generally communicates with the first valve assembly and the third valve assembly. The third valve assembly communicates with the first valve assembly, second valve assembly and fourth valve assembly. The third valve assembly prevents passage of liquid fuel from the tank to the canister. The fourth valve assembly manages flow from the valve.
