ABSTRACT:
A fuel vapor treatment device or canister for a vehicle evaporative emission control system has a casing filled with a fuel vapor absorbent material in its chamber. A relay pipe projects outwardly from one end the casing and communicates with the chamber. A liquid-fuel separator having a cavity is sealingly mounted to the one end of the casing so that the relay pipe extends into the cavity. Inlet and outlet pipes, which communicate with the cavity and fuel vapor, are formed in the separator. A fuel vapor outflow passage is formed inside the separator and communicates with the outlet pipe. The suction pipe has a reduced size section with an orifice. A liquid-fuel suction pipe, which communicates with the outflow passage through the orifice, extends perpendicularly downwardly from the outflow passage. The suction pipe extends from the orifice to the area where the liquid-fuel collects.
