FUEL VAPOR RECOVERY APPARATUS

摘要

A fuel vapor recovery apparatus includes an adsorbent canister capable of capturing fuel vapor produced in a fuel tank, a purge passage connecting the adsorbent canister to an intake passage of an engine, and a purge pump for delivering fuel vapor from the adsorbent canister to the intake passage via the purge passage. The purge pump has a pump part and a motor part configured to drive the pump part. The fuel vapor recovery apparatus further includes a prevention mechanism for preventing liquid fuel liquefied from the fuel vapor in the purge passage from entering the motor part through the pump part.
