Patent ID: 8375988

Claim:
A baffle device configured to be disposed near an outlet of a fuel tank having a fuel-containing space, the baffle device comprising: a fitting having an aperture therethrough; a first baffle including a passageway in fluid communication with the aperture in the fitting; an opening positioned opposite the fitting and directly exposing the passageway to the fuel-containing space; a first baffle length; a first baffle aperture configured to permit entry of fuel vapor into the passageway and exit of fuel vapor from the passageway; and a second baffle overlying at least a portion of the first baffle aperture and including a second baffle length; a second baffle aperture configured to be positioned in the fuel-containing space and configured as a longitudinal slot in the second baffle extending the entire length of the second baffle; wherein the first and second baffles define a gap therebetween through which fuel vapor is permitted to flow, and wherein the first baffle length is greater than the second baffle length, thereby inhibiting coalescence of fuel in the gap.
