6 0 -2- FUEL DISPENSING SYSTEM The present invention relates to fuel dispensing systems and more particularly to fuel dispensing systems for dispensing gasoline, liquefied petroleum gas or diesel engine fuel for automotive use.
Conventionally, filling stations for dispensing fuel for automotive use comprise a series of pumping or dispensing units on the forecourt of the filling station. Each unit is connected to a remote storage tank from which fuel is withdrawn when a user removes the 10 filling nozzle from a storage cradle on the dispensing unit and actuates the dispensing trigger on the nozzle. The dispensing unit may have a single outlet or multiple outlets. For each respective outlet the dispensing unit includes a meter and an air eliminator/solenoid valve within the fuel line upstream of a connector for the dispensing hose. The meter accurately records the amount of fuel dispensed at each operation with corresponding data being transmitted to a display at or adjacent to the dispensing unit and, usually, also to a cashier's unit. The air eliminator acts to eliminate air from the fuel line while the solenoid valve opens or closes the fuel line to control the flow of fuel to the dispensing hose.
Traditionally, each dispensing unit is mounted above-ground on a suitable base, with the meters and air eliminator/solenoid valves and other pumping-associated equipment being installed within the lower part of the casing of the dispensing unit. _As a result, the casing of the dispensing unit at least in its lower part is relatively bulky. The bulkiness of the casing restricts access to the dispensing unit and as a result access is normally restricted to a predetermined position in a lane at one or both sides of the dispensing unit. Also, the dispensing unit is prone to damage by careless drivers, resulting in the necessity for relatively frequent repair of the casing and of components within the casing which might be damaged as a result of low speed impact by a vehicle.
According to the present invention, there is provided a dispensing system for automotive fuel, said system comprising a casing mounted within the ground and containing p:\opER\RSH\PP0407-9.SPE 10111/98 -3a fuel flow meter and an associated valve, said meter being linked by a fuel line to a fuel tank, said dispensing system further comprising above-ground structure supporting a dispensing hose to which the meter and associated valve within the casing are linked.
Preferably the meter and associated valve within the casing are linked by a delivery line passing externally of the casing, the casing being adjacent to but separate from the aboveground structure whereby the above-ground structure is mounted independently of the casing.
Further according to the invention, there is provided a dispensing system for S° automotive fuel, said system comprising a casing mounted within the ground and containing a fuel flow meter and an associated valve, said meter being linked by a fuel line to a fuel S: tank, said dispensing system further comprising above-ground structure supporting a dispensing hose to which the meter and associated valve within the casing are linked by a delivery line passing externally of the casing, the casing being adjacent to but separate from the above-ground structure whereby the above-ground structure can be located (and preferably 15 is located) in a selected position independent of the position of the casing.
S@ 0.
S•Still further according to the invention, there is provided a dispensing system for oooo• automotive fuel, said system comprising a casing mounted within the ground and containing Sa fuel flow meter and an associated valve, said meter being linked by a fuel line to a fuel 20 tank, said dispensing system further comprising above-ground structure supporting a dispensing hose to which the meter and associated valve within the casing are linked by a delivery line passing externally of the casing, the casing being separate from the aboveground structure whereby the structure can be located (and preferably is located) in a selected position wholly to one side of the casing.
Still further according to the invention, there is provided a dispensing system for automotive fuel, said system comprising a casing mounted within the ground and containing a fuel flow meter and an associated valve, said meter being linked by a fuel line to a fuel tank, said dispensing system further comprising above-ground structure supporting a dispensing hose to which the meter and associated valve within the casing are linked by a P:\PER\R\PL0407-9.SPE 10111/98 -4delivery line passing externally of the casing, the casing being adjacent to but separate from the above-ground structure whereby each is supported from the ground independently of the other. There may be more than one above-ground structure (supporting a hose), and at least one of said structures is supported by the ground independently of another.
When the dispensing system has multiple outlets, the housing within the ground includes a meter and associated valve for each outlet, and the above-ground structure carries a hose for each outlet.
Advantageously, the housing within the ground has a removable cover at or adjacent ground level, the cover preferably being of sufficient strength to carry the weight of a vehicle.
Advantageously, the above-ground structure can be in the form of a column.
15 An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: S• Figure 1 is a schematic vertical section of a dispensing system in accordance with a 00* S" preferred embodiment of the invention and comprising an in-ground housing and aboveground structure; and 20 Figure 2 is a plan view showing schematically the arrangement of components within the in-ground housing.
The dispensing system of the preferred embodiment of the invention has conventional flow meters 2 and air eliminator/solenoid valves 4 housed within a casing or sump 6 within the ground and closed by a cover 8 substantially at ground level, the casing 6 having a bottom wall 6a and a side wall 6b. The casing 6 may also contain associated electronic components such as electrical switching boxes and junction boxes. With this arrangement the substantive structure of the dispensing system situated above ground level adjacent to the casing 6 can then simply consist of structure 10 sufficient to carry the dispensing hoses 12 and cradles 14 for the nozzles, and also a display 16 for viewing by the user, eg. of sales information such as volume and/or sales price of fuel. More particularly, the structure 10 can thus be in the p:\OPER\RSHPP0407-9.SPE 10/11/98 form of a relatively slender column 18 and/or may be a hollow structure comprising a support column having external cladding 26 as shown. As shown, fuel lines 20 extend from the casing 6 downstream of the air eliminator/solenoid valves 4 and pass through the column foundation 24 via flexible connections 28 and then upwardly along the column 18 or preferably through the column 18 especially inside the cladding 26 to upper hose connectors 22, the fuel lines 20 preferably exiting the casing 6 by passage through the side wall 6a. The dispensing hoses 12 hanging downwardly from the connectors 22 have conventional nozzles S. at their outlet ends and the lower part of the structure 10 simply needs to be of sufficient size to accommodate a respective cradle 14 for the or each of the nozzles.
The system just described is designed for dispensing gasoline or diesel fuel. A corresponding system for dispensing liquefied petroleum gas (LPG) will be substantially the same as that described but with the meters and associated valving within the casing 6 being of a design appropriate to that particular fuel.
By the step of mounting the fuel meters, air eliminator/solenoid valves and possibly other components in a separate casing beneath the ground rather than in an above-ground casing, the area of the above-ground structure can be significantly reduced, particularly the S* area of the lower part thereof. This provides a number of significant advantages. The 000 20 reduced area of the lower part of the above-ground structure enables greater access to vehicles within a given forecourt area which can, in turn, lead to the possibility of significant redesign away from the traditional concept of filling lanes arranged in parallel. In other words it provides far greater versatility in the design of the layout of the forecourt enabling within the area of the forecourt a greater number of dispensing outlets and/or quicker access of vehicles to and from each outlet, particularly when the upper surface of the cover 8 is at ground level and is designed to carry the weight of a vehicle whereby vehicles could possibly be driven across the cover 8. Also the location of the meters and air eliminator/solenoid valves in a separate casing underground removes these relatively sensitive components from the risk of damage arising from low speed impact by a vehicle. Although the dispensing system still has above-ground structure which might be damaged by a vehicle, that structure is not enclosing damage-sensitive components. At most, damage arising from vehicle impact is likely to involve replacement of one or two relatively inexpensive metal or plastics panels which may have been used for cladding in the above-ground structure eg. the column. It would be P:\PER\RSH\PP0407-9.SPE 10/11/98 -6possible for the above-ground structure just to consist of a substantially solid column for supporting the hoses, nozzles, and display and which could be almost totally resistant to most low speed vehicle impacts which are likely to occur in practice.
It will be noted from Figure 1 that due to the separation of the in-ground casing 6 and above-ground structure 10 these components are separately mounted to the ground with the structure 10 being to one side of the casing 6. This means that there is added versatility in the relative placement of the casing 6 and above-ground structure 10 to suit the required design of the forecourt. Also as there is no structural relationship between the casing 6 and 10 above-ground structure 10, the casing 6 does not impose constraints on the design of the Sstructure 10 and, hence, there is significant versatility in the design of the structure 10; for *0ee* example although as previously discussed the structure 10 could consist of a column which could be quite slender if it is just supporting the hoses, nozzles and display, the structure could form a more substantial column which also acts as a support for the overhead canopy S- 15 or roof of the forecourt. There may also be a canopy or roof (not shown) but with at least one above-ground structure (supporting the hose 12) independent thereof and not supporting the canopy or roof.
embodiment has been described by way of example only and modifications are possible within the scope of the invention.
