ABSTRACT:
A canister device is used to collect fuel vapors generated in a vapor space within a gasoline tank and those generated in a filler neck thereof while the tank is being filled in a vapor absorbing material accommodated therein. The accumulated fuel vapors are purged from the canister utilizing the source of vacuum generated in an intake manifold while the engine is running. The canister device includes a casing accommodating a vapor absorbing material layer, a first intake port provided at the intermediate portion of the casing and communicating with the vapor space in the fuel tank, a second intake port provided in one side wall of the casing and communicating with the interior of the filler neck of the fuel tank, an air port provided on the other side wall of the casing and opened into air ambient the casing, and a purge port communicating with the source of vacuum and positioned at a location or two of the casing such that the air flowing into the canister through the air port is discharged through the vapor absorbing material layer.
