ABSTRACT:
A one-way flow valve quick connector is used in automotive fuel tank filler systems to interconnect the fuel filler tube with the fuel tank without the use of tools or special equipment. The quick connector includes a check valve to establish a substantially hermetic seal between the tank and the environment at all times to prevent the escape of liquid fuel during the refueling process as well as the escape of toxic vapors. A bypass vent operates during the refueling process to draw any vapors escaping from the tank or entering through the fuel fill tube inlet, filtering and returning them to the fuel tank.
