초록 ▼

An apparatus is provided for controlling discharge of fuel vapor from an aperture in a vehicle fuel tank. The apparatus includes a housing mounted in the aperture and a vent valve received in the housing for movement between a closed position blocking flow of fuel vapor from the vehicle fuel tank to a vapor recovery canister and an open position allowing flow of fuel vapor from the fuel tank to the vapor recovery canister. The apparatus also is configured to use vacuum from an external supply source to move the vent valve from the closed position to the open position.

An apparatus for controlling discharge of fuel vapor from an aperture in a vehicle fuel tank, the apparatus comprising a housing mounted in the aperture, the housing being formed to include a hollow interior having a vent chamber, an outlet chamber, and a valve chamber, first partition means for providing a partition between the outlet chamber and the vent chamber, the first partition means being formed to include a first vent opening, second partition means for providing a partition between the vent chamber and the valve chamber, the second partition means being formed to include a second vent opening, means for blocking flow of fuel vapor and liquid fuel through the second vent opening in response to a change in vehicle fuel tank attitude in excess of a predetermined amount, the blocking means being received in the valve chamber for movement therein, a vent valve mounted in the housing for movement between a closed position blocking the flow of fuel vapor between the vent chamber and the outlet chamber through the first vent opening and an open position allowing flow of fuel vapor from the vent chamber through the first vent opening to the outlet chamber, means for using vacuum to move the vent valve from the closed position to the open position, the using means including a control chamber and an external vacuum supply line, the vent valve being mounted to communicate with vacuum extant in the control chamber, conduit means for communicating negative pressure from the vehicle fuel tank through the second vent opening to the control chamber in the using means to generate a vacuum in the control chamber without using the external vacuum supply line, the conduit means extending through the vent valve, and a relief valve positioned in the conduit means and movable between a closed position blocking flow of air from the control chamber in the using means through the conduit means to the vehicle fuel tank and an open position allowing flow of negative pressure from the vehicle fuel tank through the conduit means and through the second vent opening to the control chamber to generate a suction force moving the vent valve from the closed position to the open position in response to reduction of fuel vapor pressure in the vehicle fuel tank to below a predetermined level so that ambient air in the outlet chamber flows into the vehicle fuel tank through the first vent opening to increase the fuel vapor pressure in the vehicle fuel tank.
