    摘要: A vapor storage canister incorporates a liquid trap that protects the carbon bed, but which avoids purging liquid directly out of the trap. The trap consists of a cup that forms an interior cavity at the bottom of, and surrounded by, the carbon bed. The purge tube does not enter the trap directly, but instead runs to a plenum that draws from the bottom face of the carbon bed. The trap, in turn, is open to the interior of the carbon bed only through a screen mesh grid. Consequently, vapor can be pulled from the trap at purge, but not liquid.

    摘要: A fuel tank filler neck has a partition providing a vent orifice for vapor flow from a fuel introduction tube to a vapor discharge fitting. A ball valve guided beneath the orifice is adapted to float into engagement across the orifice to prevent liquid fuel from passing through said orifice. A filler neck restrictor plate is carried on an actuating arm that has a cam surface engaging the ball valve. The cam surface engages the ball valve across the orifice to inhibit flow of fuel vapor through the orifice when the restrictor plate inhibits introduction of fuel through the filler neck, and permits the ball valve to drop away from the orifice to permit flow of fuel vapor through said orifice when the restrictor plate permits introduction of fuel through the filler neck.

    摘要: A fuel vapor storage canister includes a vapor inlet for introducing vapor into the canister and a bed of adsorbant material in fluid communication with the inlet for adsorbing vapor within the canister. A vapor purge tube is in fluid communication with the bed for purging fuel vapor from the bed. A thermoelectric cooler/heater selectively cools the inlet tube to promote condensation of vapors therein and selectively and alternatively heats the bed to promote purging of vapors from the bed and the remainder of the canister.
