Flange mounted valve manifold
View Patent ↗A flange assembly 10 is provided for a fuel supply unit of a vehicle. The assembly 10 includes a flange 12 constructed and arranged to cover an opening in a fuel tank. The flange has an interior portion constructed and arranged to be exposed to fuel. The interior portion is in communication with an outlet 15 provided at an exterior of the flange. A plastic manifold 16 is mounted to the interior portion of the flange so as to communicate with the outlet. The manifold is constructed and arranged to mount at least one fuel supply component 22 thereon.
1. A flange assembly for a fuel supply unit of a vehicle, the assembly comprising:
a flange constructed and arranged to cover an opening in a fuel tank, the flange having an interior portion constructed and arranged to be exposed to fuel, the interior portion being in communication with a vapor receiving outlet provided at an exterior of the flange,
a plastic manifold separate from and mounted to the interior portion of the flange so as to communicate with the vapor receiving outlet, the manifold being constructed and arranged to mount at least one fuel supply component thereon, and
a seal between the manifold and the interior portion of the flange,
wherein the assembly is in combination with a vapor vent valve as the at least one component, the vapor vent valve being separate from and mounted to the manifold and in direct communication with the vapor receiving outlet such that vapor in the fuel tank may pass through the vent valve and to the vapor receiving outlet, and
wherein the interior portion includes a boss extending from an interior surface of the flange, the manifold being coupled to the boss in a snap-fit arrangement.
2. The assembly of claim 1 , wherein the flange is metal.
3. The assembly of claim 1 , in further combination with a grade vent valve constructed and arranged to permit fuel vapor to pass there-through in the event of a vehicle roll-over, the manifold including a portion in communication with the outlet, the portion receiving the grade vent valve.
4. The assembly of claim 1 , wherein the seal is an O-ring.
5. The assembly of claim 1 , wherein the manifold includes at least one support member constructed and arranged to couple with the vent valve in the snap fit arrangement.
6. The assembly of claim 1 , wherein the manifold includes surfaces defining a generally cylindrical opening that communicates with the outlet, a portion of the vent valve being received in the generally cylindrical opening.
7. A flange assembly for a fuel supply unit of a vehicle, the assembly comprising:
a flange constructed and arranged to cover an opening in a fuel tank, the flange having an interior portion constructed and arranged to be exposed to fuel, the interior portion being in communication with a vapor receiving outlet provided at an exterior of the flange,
means for mounting at least one fuel supply component thereon, the means for mounting being separate from and coupled to the interior portion of the flange so as to communicate with the vapor receiving outlet, and
a seal between the means for mounting and the interior portion of the flange,
wherein the assembly is in combination with a vapor vent valve as the at least one component, the vapor vent valve being separate from and mounted to the means for mounting and being in direct communication with the vapor receiving outlet such that vapor in the fuel tank may pass through the vent valve and to the vapor receiving outlet, and
wherein the interior portion includes a boss extending from an interior surface of the flange, the means for mounting being coupled to the boss in a snap-fit arrangement.
8. The assembly of claim 7 , wherein the flange is of metal material and the means for mounting is of plastic material.
9. The assembly of claim 7 , in further combination with a grade vent valve constructed and arranged to permit fuel vapor to pass there-through in the event of a vehicle roll-over, the means for mounting including a portion in communication with the outlet, the portion receiving the grade vent valve.
10. The assembly of claim 7 , wherein the seal is an O-ring.
11. The assembly of claim 7 , wherein the means for mounting includes at least one support member constructed and arranged to couple with the vent valve in the snap fit arrangement.
12. The assembly of claim 7 , wherein the means for mounting includes surfaces defining a generally cylindrical opening that communicates with the outlet, a portion of the vent valve being received in the generally cylindrical opening.
13. A method of providing a flange assembly for a fuel supply unit of a vehicle, the method includes:
providing a flange constructed and arranged to cover an opening in a fuel tank, the flange having an interior portion constructed and arranged to be exposed to fuel, the interior portion being in communication with a vapor receiving outlet provided at an exterior of the flange,
mounting a plastic manifold separate from the flange to a boss, extending from the interior portion of the flange, in a snap-fit arrangement so as to communicate with the vapor receiving outlet,
providing a seal between the manifold and the flange, and
mounting at least one fuel supply component on the manifold, wherein the at least one fuel supply component is a vapor vent valve separate from the manifold and in direct communication with the vapor receiving outlet.
14. The method of claim 13 , wherein the step of providing the seal includes providing an O-ring as the seal.
