Abstract
A tank venting control valve assembly is provided to regulate discharge of liquid fuel and fuel vapor from a fuel tank. The assembly closes automatically to prevent discharge of agitated liquid fuel from the tank or block overfilling of the tank. The assembly opens automatically after agitation of liquid fuel in the tank has subsided or refueling has been completed to cause the fuel level in the tank to fall.
