    'lä FUEL BLEÉNDING HÜSEÉ AND FUEL DlSPENSlNG UNlT 'fechnical fieldThe invention relates to a fuel liose for delivering rriultiple~gr'ades offuel, and a fuel dispensing unit having such a fuel hose, Background artSolna fuel dispensing systems include rnultiplegrade fuel sources with single or multiple fuel outlets for dispensing various grades of fuel. Each fuelsource ntay include a pump to dispense the fuel from its source to itsrespective meter for measuring the volume of fuel. The fuel then remains inits original concentration or it is olended with other fuels to form a separateconcentration before teaching the filel outlet. A problem with these systemsoccurs when a single fuel outlet or fuel line dispenses multiple grades of fuel.Lower grades of fuel cart rernain in the system while the user attempts toobtain a higher grade of fuel. This contamination can often present a lowergrade of fuel than required. One solution is to leave the lower grade of fuel inthe system and combine it with higher grade, hoping that the combinationwould have sufficient grade to satisfy state and federal regulations. However,this can he disadvantageoiis for users who only dispense a small volume offuel since the volume within the systern creates a large variation on the gradeof the fuel and places a design lirnitation on the system due to the smallvolume. Artother solution is to place residual high grade fuel in the systern inorder to compensate for the lower grade fuel previously dispensed. However,this can cornplicate the system and fail to give the user the expected grade offuel when the highest grade has been selected or a small volume is desired.US~5,908,055 discloses a fuel dispenser for dispensing different typesof fuel. The fuel dispenser has a dispenser housing and a fuel pumping unitfor each type of fuel to be dispensed mounted in the dispenser housing, Thefuel dispenser further has a hose comprisiitg three separate fuel lines fordispensing three various grades of fuel. A problem with such a hose is that itrequires a large diameter which makes the hose inflexiole. Another problem is 2G that since the ftiel lines will have to he small in order to fit within the hose, thefuel flow rate in said fuel lines will oe limited.
    Summarv of the inventiori lt is an objective of the present invention to provide en iniproverrierit ofthe ahove technique and prior art. More particularly, it is an objective of thisinvention to provide an improved fuel hose for dispensmg several differentgrades of fuel with rniriirriai oontantination.
    According to a first aspect, these and other objects, and/or advantagesthat will he apparent from the following description of ernbodiinents, areachieved, in full or at least in part, hy a fuel hose for delivering mtiltiplegrades of fuel, comprising a first hose portion having a first length and a firstdiameter, and a second hose portion having a second length and e seconddiameter. The first hose portion coniprises a first fuel line and a second fuelline, and the second hose portion comorises a third fuel line, the first fuel lineand the second fuel line being fluidly connected to the third fuel line. The fuelhose is oharacterized in that the first diameter of the first itose portion issubstantially larger than the second diameter of the second hose portion. Thefuel lines are separated in the first hose portion and the problem ofcontarninatiori is therefore iiinited to the second hose portion. The fuel hose isfurther advantageous in that the second diameter of the second hose portion,which is the hose portion that is moved around and handed by the user duringrefueling, is smaller than the diameter of the first hose portion, This allows thefirst hose portion to accomrnodate a plurality of fuel lines while the secondhose portion (accornmodating one fuel line only) will be kept flexiole and user-friendly due to its srnailer diameter. Further, the larger diameter of the firsthose portion rnay accornmodate fuel lines having a diameter that provides fora satisfying fuel flow rate in the fuel hose.
    The first length of the first hose portion may be longer than the secondlength of the second hose portion. This is adventageous in that the part of thehose that risks oontarninating the fuel, when a user attempts to obtain ahigher grade of fuel and there are remains of lower grades of fuel left in thehose, will be kept to a lninimum. The fuel lines are separated in the first hose CF: portion end the proolern of conternination is therefore limited to the secondhose portion, which portion has a iengtli sniailer' than the iength of the firsthose portion ln one preferred ernbodiment of the invention, the first fuei line inay headapted to deliver e fuel of a first grade, the second fuei iine is adapted todeiiver a fuel of a second grade, and the third fuel line is adapted to deiiver afuei of the first grade, the second grade or a ntix of the first grade and thesecond grade. The first grade may ioe 92 octane, the second grade ntay he98 octene, and the mix of the first grade and the second grade nway he 95ootane.
    The first fuel line and the second fuel ilne may be coaxially arranged inthe first hose portion, which is a space efficient solution that helps keeping thefirst diameter of the first hose portion to a minimum.
    The fuel hose may further cornprise a vapour recovery line extendingwithin the first hose portion and the second hose portion. The vapourreoovery is performed hy a system which is incorporeted in the fueldispensing unit, such that vapour of hydrooarbons are prevented fromesoaping to the erivironnient outside the tank of the motor vehicle. Thevapour recovery line, the first fuel line and the second fuel line is prefershlycoaxially arrenged in the first hose portion of the fuel hose, and the vepourrecovery line and the third fuel line is preferably coaxiaily arranged in thesecond hose portion of the fuel hose.
    The first hose portion may suhstantially extend from a top section of afuel dlspensing unit to a bottom section of the fuel disperising unit, artd thesecond hose portion may substantielly extend from the bottom section of thefuel dispensing unit to a mid section of the fuel dispensing unit. This way, thepart of the fuel hose with the smaller diameter' (ie. the second hose portion)will constitute the part of the fuel hose that is moved around and handed hythe user during refueling. in turn, the fuel hose wiil he flexihle and user-friendly. Preferahly, the first length of first hose portion oonstitutes at least 4/7of the entire length of the fuel hose. Natureliy, other cortfigurations of the fuelhose ere possible. For example, the first hose portion may suhstantiallyextend from the mid section of the fuel dispensing unit to the top section of 'iO the fuei disperisiitg unit and frorn the top section of the tuei dispertsirtg unit tothe bottom section of the fuel dispensing unit, and the second hose portionrnay stihstantiaiiy extend front the bottom section of the tue! dispensing unit tothe rnid section of the fuet dispensing Linit.
    Tho first ltose portion may be connected to the second hose portion hymeans of a connection means, or the first hose portion and the second hoseportion may he integraily torrned. Both are preferred ernbodirnents of theinvenfion.
    According to a second aspect, these and other objects are achieved, inftili or at least in part, hy e fuei dispensing unit for retueiing a vehicle,comprisiitg e fuel hose according to the features described shove.
