CLOSURE DEVICE FOR CONTROLLING EVAPORATIVE EMISSIONS FROM A FUEL TANK |
| 摘要 |
A closure device, such as a fuel cap, for controlling evaporative emissions from a fuel tank. In one aspect, the invention comprises: a housing defining an internal chamber about a central axis; a diffuser plate positioned within the internal chamber that separates the internal chamber into an upper zone and a lower zone; a hydrocarbon adsorbing media disposed in the upper zone of the internal chamber; an inlet passageway for introducing fuel vapor from a fuel vapor inlet port to the lower zone of the internal chamber; and at least one outlet passageway extending from the upper zone of the internal chamber to an atmospheric air outlet port. |
