Patent ID: 8474439

Claim:
A fuel vapor processor comprising: a fuel tank; a canister for trapping fuel vapor generated in the fuel tank; a vapor pipe for leading the fuel vapor from the fuel tank into the canister; a recovery pipe for recovering the fuel vapor trapped in the canister into the fuel tank; a fuel pump provided in the fuel tank; a negative pressure generator for generating negative pressure depending on an amount of fuel supplied to the negative pressure generator from the fuel pump, where the fuel vapor trapped in the canister is recovered through the recovery pipe into the fuel tank due to the negative pressure; a pressure regulator connected with the fuel pump for returning excess fuel discharged from the fuel pump into the fuel tank; a fuel intake pipe for directly connecting the negative pressure generator with the fuel pump; and a fuel intake regulator disposed on the fuel intake pipe for controlling the amount of the fuel supplied to the negative pressure generator from the fuel pump.
