| 20090173231 | Carbon canister with valve activated by weight of saturated carbon - A carbon canister with a valve activated by the weight of nearly saturated or saturated carbon communicates with piping from an underground tank. The invention includes carbon within a casing inside a canister, a weight actuated valve, and piping in communication with the atmosphere. When an ORVR vehicle refuels, the pressure lowers in the tank that draws air into the canister. After refueling, the tank remains subject to conditions that generate hydrocarbon vapors. Those vapors then return to the canister and adhere to the surface of the carbon. The carbon, heavier with hydrocarbons, lowers the canister and closes the weight actuated valve. Closing the valve returns pressure control to an external pressure vacuum relief valve. The next refueling draws in atmospheric air to purge the hydrocarbons in the canister and thus lighten it. A secondary purge valve also removes hydrocarbons from the canister. Once the carbon lightens, the inlet valve opens and the vapors return to the canister for adsorption. This cycle regenerates the carbon. | 07-09-2009 |
