Definitions

  • the Present invention relates to a system for providing a fuel meter in a fuel dispensing unit.
  • the system comprises a fuel volume metering housing having an inlet side, an outlet side, and two independently operable volume metering chambers connecting the inlet side and the outlet side.
  • fuel meters are arranged in the fuel dispensing unit. Today several different fuel meters exist, and it is common to differently arrange the meters within the fuel dispensing unit in order to achieve a specific fuel dispensing unit configuration.
  • fuel dispensing unit configuration is a dispenser providing one fuel quality, e.g. 95 octane petrol, from a fuel hose on one side (A-side) of the fuel dispensing unit, and another quality, e.g. 98 octane petrol, from a fuel hose on the other side (B-side) of the fuel dispensing unit.
  • Another fuel dispensing unit configuration is a dispenser providing the same fuel quality on both sides (A-side and B-side) of the dispensing unit.
  • fuel may simultaneously be dispensed from both sides of the dispenser, both in case of same type of fuel on both dispenser sides and in case of different fuel types on the dispenser sides.
  • Yet another configuration is a fuel dispensing unit providing fuel only on the A-side, and yet another is a fuel dispensing unit providing fuel only on the B-side.
  • fuel meter devices are arranged in pair for reflecting the A-side and B-side of the dispenser, and usually two fuel meter devices are connected to, for example, a common pumping unit arranged in the dispenser.
  • fuel dispensing configurations exist were the fuel meter is connected to different sources of fuel flow, resulting in different fuel meters. Yet another fuel meter configuration consists of different fuel flow outputs from the fuel meter, since specific and different national maintenance needs must be satisfied.
  • a problem with present fuel meters is that they require complex connections and additional piping devices if all the fuel dispensing unit configurations described above shall be achieved.
  • a particular object is to provide a fuel meter arrangement where the need for complex connections and piping is obviated, or at least alleviated, while a plurality of fuel dispensing unit configurations still are to be achieved.
  • Yet another object is to provide a fuel meter arrangement having a low material cost, a simple manufacturing process and an efficient assembly procedure.
  • a system for providing a fuel meter in a fuel dispensing unit comprising:
  • the different variants of the inlet interface component provides a possibility to control how the flow of fuel is directed to and/or cut of from respective metering chamber. Said control is achieved by, during assembly, selecting appropriate inlet interface component and optionally by associating each metering chamber with a respective fuel dispenser side.
  • the system providing the fuel meter is highly advantageous since it facilitates the provision of different fuel dispenser configurations due to the different variants of the inlet interface component.
  • the inlet interface component has a relatively low cost owing to a simple mechanical construction.
  • the invention reduces the overall cost for arranging a fuel meter in a fuel dispenser by providing a modular system, in which a single base unit, which is the same for all dispensing unit configurations, is combined with different inlet components.
  • the at least two mutually different variants of the inlet interface component may be any two of:
  • the first inlet interface variant is adapted for inletting a single fuel quality to both volume metering chambers and the second inlet interface variant is adapted for inletting different fuel qualities to the respective fuel volume metering chambers.
  • the third inlet interface variant blocks the inlet of one fuel volume metering chambers, and is hence adapted for fuel flow through only one of the fuel volume metering chambers, while the fourth inlet interface variant is adapted for inletting fuel from at least two fuel sources to only one of the fuel volume metering chambers.
  • the system may comprise at least two further mutually different variants of the inlet interface component, where the first inlet interface variant has the form of a piping component for connecting at least one fuel conduit to the volume metering housing, and the second inlet interface variant has the form of a fuel pump section for connecting a fuel pump to the volume metering housing.
  • This first inlet interface variant is hence adapted for being connected to a fuel dispensing unit element, while the second inlet interface variant is adapted for being integrated with a fuel pumping device.
  • these two variants may be freely combined with any of the earlier four described variants of the inlet interface component, thus creating totally eight variants.
  • connection to a fuel dispensing unit element or a fuel pumping device makes the system more versatile, and since the inlet interface component has a low cost of manufacture, more cost efficient dispenser configurations are again possible.
  • the fuel volume metering housing may be connectable to the inlet interface component in at least two mutually different positions, said volume metering housing and inlet interface component in the second position being rotated 180° relative to each other as compared to the first position.
  • Interchanging the respective positions provides, for example, when single sided dispenser configuration is desired, a possibility to select from which side of the fuel dispensing unit the fuel shall be dispensed.
  • the selection is done by flipping the metering housing between two mounting position on the inlet interface component, causing the respective positions of the two volume metering chambers to mutually change.
  • the volume metering housing has one of its volume metering chambers associated with one side of the dispenser, and the other volume metering chamber associated with the other side of the dispenser.
  • the system may comprise at least two mutually different variants of the outlet interface component, which are interchangeably connectable to the outlet side of the fuel volume metering housing.
  • the different variants of the outlet interface component provides a possibility to control how the flow of fuel is directed and/or prevented from respective metering chamber. Said control is achieved by, during assembly, selecting appropriate outlet interface component.
  • the inlet interface component has a relatively low cost owing to a simple mechanical construction, and combining different outlet components with a single base unit further reduces the overall cost for arranging a fuel meter in a fuel dispenser.
  • outlet interface variants make it possible to direct fuel in several different ways to a fuel dispensing nozzle, by applying a low cost interface component that is conveniently connected to the chambers.
  • the at least two mutually different variants of the outlet interface component may be any two of:
  • the first outlet interface variant is adapted for directing fuel to fuel nozzles arranged on different sides of the fuel dispenser.
  • the second outlet interface variant is adapted for directing fuel to only one side of the dispenser, since this outlet interface variant blocks the outlet of one of the volume metering chambers.
  • the third outlet interface is adapted for an increased flow of fuel to a nozzle, since the flow of fuel through both of the of the volume metering chambers are combined after exiting the chambers.
  • At least one of the at least two mutually different variants of the outlet interface component may comprise at least one check valve opening or check and release valve opening.
  • a check valve satisfies national regulations and consumer demands, and may be employed with any of the outlet interface variants.
  • the fuel volume metering housing may be connectable to the outlet interface component in at least two different mutual positions, said volume metering housing and outlet interface component in the second position being rotated 180° relative to each other as compared to the first position.
  • the system may have only one of the independently operable volume metering chambers provided with metering means for generating a volume metering signal, or the system my have both independently operable volume metering chambers provided with a respective metering means, each metering means generating a respective volume metering signal.
  • outlet interface components may be connected to an outlet interface component of another fuel volume metering housing, for the purpose of common fuel communication.
  • an increased flow of fuel may be dispensed from a fuel nozzle on one side of the fuel dispenser.
  • the different inlet interface components and/or the outlet interface component may be cast or sintered in a metallic material or composite material.
  • a system having two mutually different variants of the outlet interface component provides the advantages discussed above, and this system may be combined with any variant of inlet and outlet interfaces described above, including how they are positioned in relation to other components.
  • fuel dispensing units comprising at least one of the above described inlet interface components, and/or at least one of the above described outlet interface component.
  • the dispensing units also comprise the variants of how interface components in relation to other components are positioned.
  • Fig. 1 and 7 illustrate a fuel meter system 2 for providing a fuel meter in a fuel dispensing unit 1 having a first side A and a second side B.
  • the system 2 comprises a fuel volume metering housing 3 having an inlet side 4, an outlet side 5, and two independently operable volume metering chambers 6a, 6b connecting the inlet side 4 and the outlet side 5.
  • An inlet interface component 7 is connected to the inlet side 4 of the fuel volume metering housing 3, and an outlet interface component 8 is connected to the outlet side 5 of the fuel volume metering housing 3, and thereby the inlets and outlets of the volume metering chambers 6a, 6b are covered by the interface components 7, 8.
  • Metering means 13 are arranged in a metering chamber 6a, 6b, and have the form of a screw spindle counter adapted to generate electronic pulses corresponding to the fuel flow rate when dispensing fuel from the dispensing unit 1.
  • two metering means are arranged in respective metering chamber, as described below.
  • One metering chamber 6a associated with the first side A of the dispenser 1 is, via the outlet interface component 8 and a fuel hose 20a, connected to a dispenser nozzle 21a.
  • the same metering chamber 6a is upstream, via the inlet interface component 7 and an upstream fuel line 23a, connected to a fuel tank 22a.
  • the other metering chamber 6b is correspondingly associated with a nozzle 21b, hose 20b, an upstream fuel line 23b and fuel tank 22b.
  • the upstream fuel lines 23a, 23b incorporate pumping means (not shown) for transporting the fuel, and the fuel dispenser 1 has control means (not shown) for controlling the dispenser 1 and flow of fuel.
  • the fuel flow enters the inlet interface component 7 via the upstream fuel line 23a, 23b, passes the inlet interface component 7 and enters the fuel volume metering housing 3 on its inlet side 4.
  • the fuel flows through the metering chambers 6a, 6b, which causes a rotation of the metering means 13, and then the fuel exits the volume metering housing 3 via its outlet side 5.
  • the fuel enters the outlet interface component 8, and finally exits the outlet opening 16 of the outlet interface component 8, which outlet is connected to the fuel hose 20a, 20b.
  • Inlet and outlet interface components 7, 8 are preferably made of a cast or sintered metal alloy, a composite material and/or a combination thereof.
  • the interface components 7, 8 are typically directly mounted to the metering housing 3 by means of convectional machine screws (not shown), preferably with elastomeric sealing members in-between.
  • Fig. 2a and 2b illustrates two variants 9, 10 of the inlet interface component 7, were the one variant 9 has one fuel port 18 that is common for both metering chambers 6a, 6b of the volume metering housing 3.
  • the other variant 10 has two independent fuel ports 18a, 18b connected to one metering chamber 6a, 6b respectively, for purpose of keeping different fuel types separated.
  • the fuel lines 23a, 23b upstream the fuel ports 18a, 18b are separated all the way from the fuel tanks 22a, 22b, while the former variant 9 has a common inlet. Since fuel are passing both metering chambers 6a, 6b, metering means 13 are arranged in both chambers 6a, 6b.
  • fuel exit the outlet interface component still separated and flows to respective fuel nozzle 21a, 21b.
  • Fig. 5a, 5b, 6a and 6b illustrate another variant were fuel flows only through one of the metering chambers 6a, 6b, and metering means 13 are arranged only in said one metering chamber 6a or 6b.
  • the other chamber is blocked, either i) by a blocked fuel port in the inlet interface component, ii) by the chamber 6a or 6b being blocked, or iii) by the outlet interface component not providing an inlet for the fuel.
  • This variant is used when fuel shall be directed to the first side A of the fuel dispenser, and by changing what port is blocked, fuel is directed to the second side B of the dispenser, thus providing a fourth variant.
  • a connection component 19 By arranging a connection component 19 on an interface component 7 having a fuel port common for both metering chambers, the port may be converted to a single port for fuel communication with only one chamber.
  • a fuel port of an inlet interface component is provided for only one metering chamber 6a, 6b, and by associating fuel dispenser sides A, B with the chambers, it is possible, by correctly flipping and mounting corresponding metering chamber to the fuel port, to utilize the same inlet interface component for both dispenser sides.
