摘要： An evaporative fuel treatment apparatus for a vehicle includes a direct purge channel for supplying evaporative fuel to a purge channel without involving a canister; a purge control valve for controlling communications between the canister and an air-intake system of an internal combustion engine by an opening and closing operation; a direct purge control valve for controlling communications between a fuel tank and the air-intake system by another opening and closing operation; and a two-way valve provided in a charge channel. During a purge mode of the apparatus, evaporative fuel adsorbed in the canister is purged to the air-intake system by closing the direct purge control valve and opening the purge control valve during operation of engine. During a direct purge mode of the apparatus, evaporative fuel in the fuel tank is purged to the air-intake system by closing the purge control valve and opening the direct purge control valve.

摘要： An evaporated fuel treatment device is provided to treat evaporated fuel by using a fuel supply cap with a small size while the flowout of fuel can also be suitably prevented. The evaporated fuel treatment device includes a positive pressure adjusting valve which opens when an inner pressure of a fuel tank becomes a predetermined pressure or more, and a spherical rollover valve which closes the positive pressure adjusting valve when the fuel tank is inclined at an angle equal to or larger than a predetermined angle. The positive pressure adjusting valve and the spherical rollover valve are mounted on one cylindrical portion formed on a fuel supply cap.
