Abstract

A series of specifically shaped hollow pipe plugs and correspondingly shaped hollow sockets arrangements that only fit each other. The hollow plugs of a specific shape fit over the end of/or replace existing round fuel pump nozzles. The hollow sockets with corresponding shape fit inside the vehicle's fuel filler pipe aperture. <IMAGE>

Description

WRONG FUEL ELIMINTORS This invention relates t Fuel Pump Nozzles.

In Britain the Filling stations are equipped with fuel pump nozzles that allow all types of fuel to be put into any type of vehicle regardless of whether the engine requires Diesel, leaded petrol or unleaded petrol Not that long ago, most vehicles ran on petrol of various octane or Star rating and it did not do any harm if the wrong petrol was used occasionally.

A few vehicles, mostly commercials, ran on diesel and these diesel pumps were usually to be found at the rear of the filling station or at least well away from the petrol pumps.

With the recent increase in diesel engined cars these diesel pumps have found their way on to the main isles in the filling stations alongside petrol pumps.

A few years ags with the introduction of Unleaded petrol many people had conversions carried out to their vehicles to allow them to run on unleaded. The conversions allowed the vehicles t run on both leaded and unleaded petrol, however with the intrc.ductic.n of catalytic converters, it is now essential to avoid leaded petrol if expensive replacement catalytic converters are to be avoided.

Modern Filling station forecourts have improvement a great deal over the last 15 Years, being much cleaner and pleasanter places ts visit but as the various fuels are often dispensed from the same pump unit, they are not as "USER FRIENDLY" as they could be and make it very easy t fill up with the wrong fuel Filling vehicles with the wrong fuel results in unnecessary expense, i.e. vehicle transportation to the main dealers f.Dr engine repairs, fuel line flushing and wasted fuel the minimum.

The contaminated fuel can nt be reused and has t be disposed of. The petrol companies may not bothered about wasted fuel despite the "GREEN ISSUE" but this type of human error can be avoided with the introduction of a small device fitted inside the vehicle filler pipe and an amendment or addition to the pump nozzles. Vehicles could be fitted with sockets to c,Drresp.-.nd with the correct fuel nozzle for their vehicle. The shape of the new nozzles would be of an overall size still small enough to fit in t.-, the existing filler pipes to ensure the filling station suffers no loss of custom.

n specific embodiment of the invention will now be described by way of example with reference t the accompanying drawings in which: Figure 1 shows an elevation of a pump nozzle assembly wit-h one of the new end type plug fittings.

Figure 2 shows an end view of the leaded petrol plug and socket type fittings.

Figure 3 shows an end view of the Diesel fuel plug and socket type fittings.

Figure 4 shows an end view cf the Unleaded petrol plug and socket type fittings.

Figure 5 shows the amended pump nozzle assembly with one Qf the new fittings located in a vehicle filler pipe.

Figure 6 shows the vehicle filler pipe with a specific fuel type socket fitted and the filler ca@ removed b unscrewing. Pump nozzle assemblies can be manufactured as an independent add on unit or as a new complete unit. The socket inserts f.vr the vehicle filler pipes could be push fits and or screwed in through the existing threaded filler cap assembly and secured with adhesive. New vehicles would be fitted with a pacifically designed filler pipe.

Referring to the drawing the pump nozzles would fit over the existing fuel pump nozzles to form a determined shape fcr the various types of fuel and the correspondingly shaped sockets.

Claims

1. A range of fuel pump nozzles in the form of specifically shaped hollow tube which only fit into correspondingly shaped tube socket arrangements that only fit each other, thus only allowing a specific liquid fuel to travel frcim feeder pipe tc filler pipe. The cverall shape of the nozzles are of a size that will allow entry intbD existing standard round fuel filler pipes cf vehicles not fitted with sets but small enough tc allow the fitting of the corresponding sockets in to existing vehicle filler pipes.

2. A fuel filling system that eliminates the human errcr of filling vehicles with the wrong fuel.

3. A two part fitting as claimed in Claim 1 or 2. which when fitted t the leaded petrol pump/line and vehicles that only run on leaded petrol will prevent other fuel pump nozzles from entering the vehicles filler pipe.

4. A twc part fitting as claimed in Claim 1 cir 2. which when fitted to the Diesel pump/line and vehicles that cnly run on Diesel will prevent other fuel pump nozzles from entering the vehicles filler pipe.

5. A two part fitting as claimed in Claim 1 or t which when fitted to the Unleaded petrol pump/line and vehicles that cnly run on Unleaded petrol will prevent c'ther fuel pump nozzles from entering the vehicles filler pipe.

6. A fuel filling system substantially as described herein with reference to Figures 1-6 of the accompanying drawing.

Amendments to the claims have been filed as follows CLAIMS 1. A range of fuel pump nozzles in the form of specifically shaped hollow tube which only fit into correspondingly shaped tube socket arrangements that only fit each other, thus only allowing a specific liquid fuel to travel from feeder pipe to filler pipe.

The The overall shape of the nozzles are of a size that will allow entry into existing standard round fuel filler pipes of vehicles not fitted with sockets but small enough to allow the fittinq of the corresponding sockets in to existing vehicle filler piDes.

3. A fuel filling system that eliminates the human error of fillina vehicles with the wrong fuel.

4. A two part fitting as claimed in Claim 1 - 3 which when fitted t the leaded petrol pump/line and vehicles that only run on leaded petrol will prevent other fuel pump nozzles from entering the vehicles filler pipe.

5. A twc part fitting as claimed in Claim 1 - 3 which when fitted to the Diesel pump/line and vehicles that only run on Diesel will prevent other fuel pump nozzles from entering the vehicles filler pipe.

6. A two part fitting as claimed in Claim 1 - 3 which when fitted t the Unleaded petrcl pmp/line and vehicles that only run on Unleaded petrol will prevent other fuel pump nczzles from entering the vehicles filler pipe.

7. A fuel filling system substantially as described herein with reference to Figures 1-6 of the accompanying drawing.
