Abstract: 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.

Abstract: An evaporated fuel processing device includes a fuel tank, a canister, an atmospheric passage, a vapor passage, an intake pipe, a purge passage, a purge pump, and a flow rate control valve. The evaporated fuel is desorbed utilizing only negative pressure in the intake pipe when sufficient negative pressure is generated in the intake pipe. The purge pump is driven to desorb the evaporated from the canister when sufficient negative pressure is not generated in the intake pipe. The purge pump and the flow rate control valve may be provided in the purge passage. The purge pump is a vortex pump through which the gas can flow even when drive is stopped. The minimum cross-sectional area of the internal space of the flow passage of the purge pump is equal to or larger than the minimum cross-sectional area of the internal space of the other parts of the purge passage.
