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 canister adapted to store fuel vapor discharged from a fuel tank has an inlet chamber that forms a trap for liquid fuel. Fuel is purged from the canister through a purge tube that has a small liquid purge hole at the bottom of the chamber and a large vapor purge hole spaced above the bottom of the chamber.

摘要: A purge control device for an evaporative control system comprises a single housing having two solenoid actuated valves controlling parallel orifices leading from an inlet chamber to an exit flow path. The two solenoid valves have different sized orifices to provide different flow capacities. Purge flow is controlled by an electronic control module which regulates the duty cycle of the solenoids. Each valve receives its own signal so that the flow through the orifices is individually controlled.

摘要: A TVVA with a buoyant overfill protection float contains the float closely and axially slidably within a sleeve, and feeds a negative pressure created by the rapid flow of fill vapors over the outside of the sleeve into the sleeve to hold the float down and prevent it from corking.

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.

摘要: A tank vapor vent valve assembly uses a spring loaded sealing flapper door located below a normally open float chamber. The flapper door spring is specifically designed to open when the tank pressure falls, allowing make up air to pull the flapper door down and draw in make up air through the canister inlet.

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.
