Patent ID: 7255094

Claim:
A fuel vapor recovery canister comprising an elongated housing having a length and formed to include an inlet end, an exit end, and an interior region extending therebetween, a vapor-cleaning material located in the interior region, wherein the elongated housing includes a high-speed flow pipe and a tube that has a first cross-sectional area, the high-speed flow pipe has an opened end exposed to the atmosphere and a second cross-sectional area that is relatively smaller than the first cross-sectional area to cause a stream of fuel vapor flowing in the interior region of the elongated housing toward the inlet end in response to a vacuum applied to the interior region of the elongated housing at the inlet end to flow at a first velocity in the tube and at a faster second velocity in the high-speed flow pipe to hasten release of hydrocarbon material adsorbed on a portion of the vapor-cleaning material located in the high-speed flow pipe into the stream of fuel vapor flowing in the tube toward the inlet end, and wherein the exit end includes a conduit extending generally in the direction of the length of the housing for providing flow into and out of the exit end.
