Abstract:
1. A fuel vapor processing apparatus comprising: a vapor passage capable of introducing fuel vapor into a canister, the fuel vapor being produced within a fuel tank of an automobile: an atmospheric-side opening and closing device provided at the canister; a negative pressure generating device disposed within the fuel tank and capable of generating a negative pressure; a recovery passage communicating between the negative pressure generating device and the canister, so that fuel vapor contained within the canister can be recovered into the fuel tank through the recovery passage by the operation of the negative pressure generating device; and a vapor passage opening and closing device capable of opening and closing the vapor passage; a separating device capable of separating gas, which is introduced from within the fuel tank, into an air component and a fuel component; wherein during recovering of fuel vapor within the canister into the fuel tank by the operation of the negative pressure generating device, on the condition that the atmospheric-side opening and closing mechanism and the vapor passage opening and closing device are closed, the air component separated from the gas by the separation device can be supplied to the canister.
