Uppfinnare: E T Young Prioritet beglird Iran den november 1955 (USA) Foreliggande uppfinning hanfor sig till en apparat for utminutering av endera av tva vatskor eller en blandning av dessa i en av ett flertal forutbestamda proportioner, vilken apparat är sarskilt lamplig for bestamning av mangdf5rhallanden mellan grundkomponenten och tillsatskomponenten hos ett motorbransle. Inventor: ET Young Priority Accompanied by Iran in November 1955 (USA) The present invention relates to an apparatus for minimizing either of two water shoes or a mixture thereof in one of a plurality of predetermined proportions, which apparatus is particularly suitable for determining the diversity ratios between the basic component and the additive component of a motor fuel.

Numera forsaljas bilbranslen allmant i olika kvalitetsklasser, vilka utmarka sig genom olika oktantal och vilka skilj a sig till sin sammansattning framfor allt betraffande andelen av sadana material som tetraetylbly, som forlanar branslena knackningsfrihet. De av ett visst bolag salda branslena med hogre oktanvfirde Oro dyrare an av samma bolag salda branslen med lagre oktanvarde. Vanligtvis silljer varje enskilt bolag endast tva typer, namligen dels normal bensin och dels den bathe kvaliteten, som betecknas som hOgoktanig eller qiremium»-bensin, etc. Nowadays, the car industries are generally sold in different quality classes, which are distinguished by different octane numbers and which differ in their composition, above all as regards the proportion of such materials as tetraethyl lead, which gives the industries freedom of knocking. The industries sold by a certain company with higher octane values are more expensive than the industries sold by the same company with lower octane values. Usually, each individual company produces only two types, namely normal petrol and the good quality, which is described as high-octane or gyremium »petrol, etc.

Den apparattyp, has vilken uppfinningen är avsedd att tillampas, bestar av en pump, en strOmningsledning, en matare och en ventil i stromningsledningen for vardera vatskan, ett gemensamt utmatningsmunstycke, vid vilket namnda stromningsledningar sluta, och en mataraxel, som Or samordnad med varsin av matarna och som drives av den genom mataren flytande vatskan, varvid de bada mataraxlarna Over en utvfixlingsmekanism aro forbundna med en differential, som Er forbunden med namnda ventiler. En dylik apparat kannetecknas enligt uppfinningen darav, att ett par motsatt anordnade trappkugghjul Oro fastgjorda vid trappkugghjulens axlar, att kugghjul aro forbundna med vaxelhjulsaxlar och samordnade med var slit av trappkugghjulen i och for kuggingrepp efter val med de olika stegen ph trappkugghjulen, varvid namnda mataraxlar och en kugghjulsdifferen- tial aro utvaxlingsbart kopplade med utvaxlingsmekanismen over namnda trappkugghjuls- och vaxelhjulsaxlar och kugghjulsdifferentialen lr anordnad att pa.verka namnda ventiler i och fOr dessas instiillning, i fall trappkugghj ulsaxlarnasrotationshastighet joke overensstammer med det i forvag valda mangdforhallandet mellan vatskorna, sadant det bestammes genom kugghjulens ingrepp med det valda steget pa trappkugghjulen, att en inkopplingsaxel är anordnad att manovreras fOr hand frau apparatens utsida fOr att fora kugghjulen och trappkugghjulen ur kuggingrepp, att fjaderanordningar Oro anordnade att fora kugghjulen och trappkugghjulen i kuggingrepp, och att en steginstallningsaxel Or anordnad att manovreras for hand fran apparatens utsida for forflyttning av kugghjulen steg for steg utmed trappkugghjulen i dessas langdriktning till lagen motsvarande valda steg pa trappkugghjulen fOr installning av proportionen mellan vatskekomponenterna, nfir kugghjulen och trappkugghjulen Oro ur kuggingrepp. The type of apparatus to which the invention is intended to consist consists of a pump, a flow line, a feeder and a valve in the flow line for each liquid, a common discharge nozzle at which said flow lines end, and a feed shaft which is coordinated with each of the feeders and which are driven by the liquid flowing through the feeder, the two feed shafts via an exchange mechanism being connected to a differential, which are connected to said valves. Such an apparatus can be characterized according to the invention in that a pair of oppositely arranged stair gears are attached to the axles of the stair gears, that gears are connected to gear shafts and coordinated with each wear of the stair gears in and for gear engagement after selection with the various steps. a gear differential is interchangeably coupled to the gear mechanism over said stair gears and gear shafts and the gear differential is arranged to act on said valves in and for their adjustment, in the engagement of the gears with the selected step on the stair gears, that a coupling shaft is arranged to be maneuvered by hand from the outside of the apparatus to drive the gears and the gears out of the gear engagement, that spring devices are arranged to feed the gears and the gears in a gear engagement, and that a step installation shaft is arranged to be maneuvered by hand from the outside of the apparatus for moving the gears step by step along the stair gears in their longitudinal direction to the law corresponding to selected steps on the stair gears for installing the ratio of the watertight gears

Foreliggande uppfinning avser en apparat, anordnad att sakerstalla att bensinkoparen betalar fOr det han far, Oven am det han fOr mojligtvis icke Or bestambart med hog noggrannhet. Ett bestamt pris per liter Or fast-stain for grundkomponenten och ett bestamt pris per liter Or faststallt for tillsatskomponenten. Grundkomponenten och tillsatskomponenten uppmatas darefter var for sig, varvid de angivna mangderna av vardera komponenten indikeras exakt och priserna raknas individuellt och laggas ihop till det totala fOrsOljningspriset. Vad som levereras till kunden or en blandning soul miipigtvis joke har na'- gon exakt bestambar sammansattning i am grund- och tillsatskomponenter. Av tva kunder, vilka begara samma kvalitet ben- 2— sin kan den ene i verkligheten vid en speciell forsaljning erhalla en storre andel tillsatskomponent i forhallande till grundkomponenten an den andre. Priset for ett givet antal liter av bensinblandningen kommer att vara storre for den forsta kunden an for den andra, men komma hada att erhalla exakt det de betala for mom granserna for lagligen godtagbara avvikelser. De hada blandningarna, vilka avgivas pa detta salt och vilka nominellt Oro av samma kvalitet, komma dock att vara godtagbart likartade och komma att uppvisa atminstone det oktanvarde, som nominellt tillskrives kvaliteten. Sasom kommer att framga, Or i sjAlva verket felet i bestamningen av forhallandet mellan grund- och tillsatskomponenten ganska litet, och i avseende a kundens ansprak skulle han knappast kunna finna nagon skillnad mellan de tva nagot awikande blandningarna, vilka kunna levereras till honom vid skilda tillfallen, d?t han be-gar gamma kvalitet. Dessutom kommer skillnaden i det pris, som han maste betala vid olika tillfallen for samma mangd bensin av samma kvalitet att uppga till ett obetydligt be-'app. The present invention relates to an apparatus arranged to ensure that the petrol buyer pays for what he receives, even though he may not be able to determine it with high accuracy. A fixed price per liter Or fast-stain for the basic component and a fixed price per liter Or fixed for the additive component. The basic component and the additive component are then fed separately, the specified quantities of each component being indicated precisely and the prices being individually calculated and added together to the total sales price. What is delivered to the customer or a mix of soul miipigtvis joke has some exact determinable composition in am basic and additive components. Of two customers who demand the same quality, one can in reality, in the event of a special sale, obtain a larger share of additive component in relation to the basic component than the other. The price for a given number of liters of the petrol mixture will be greater for the first customer than for the second, but will have to receive exactly what they pay for the VAT limits for legally acceptable deviations. The had mixtures, which are given off on this salt and which nominally are of the same quality, will, however, be acceptably similar and will exhibit at least the octane value, which is nominally attributed to the quality. As will be seen, the error in determining the ratio between the basic and additive component is in fact quite small, and as to the customer's claim he could hardly find any difference between the two slightly different mixtures, which could be delivered to him on different occasions. , that he begs for gamma quality. In addition, the difference in the price he has to pay on different occasions for the same amount of petrol of the same quality will amount to an insignificant amount.

Uttrycket vgrundkomponenb anvandes i ovan angivna bemarkelse sasom beteckning for en bensin av lagre kvalitet. Uttrycket »tillsatskomponenb anvandes sasom beteckning for ett hogvardigt tillsatsmaterial, som i sig sjalv kan vara ett av vissa kunder begart bransIe. Tillsatskomponenten kan givetvis Oven vara ett bransle med betydligt hogre kvalitet On vad som efterfragas. Sasom ovan. framhallits, Or det speciella syftet med uppfinningen att mojliggora leverans av 100 %-ig tillsatskomponent. Uppfinningen Or foljaktli gen speciellt inriktad pa leverans av tillsatskomponenten sasom omedelhart anvandbart bransle, men uppfinningen Or joke begransad dartill och nedan beskrivna mekanism kan Oven anvandas for utminutering av blandningar, i vilka tillsatskomponenten har en kvalitetsgrad, som aldrig begares enbart. The term basic component b is used in the above remark as a designation for a petrol of lower quality. The term "additive component" is used as a term for a high-quality additive material, which in itself may be an industry requested by some customers. The additive component can of course also be an industry with significantly higher quality than what is in demand. As above. The particular object of the invention is to enable the delivery of a 100% additive component. Accordingly, the invention is particularly directed to the delivery of the additive component as an immediately usable industry, but the invention is limited thereto and the mechanism described below may also be used to minimize mixtures in which the additive component has a degree of quality which is never required solely.

I fig. 1 visas overdelen 2 av det vanliga holjet hos en bensinpump, vilket i storsta allmanhet innefattar ett hus med dari anordnad bensinpump och drivmotor jamte en bensinmatare. I overdelen av ett sadant holje Or ett rakneverk anordnat, som innefattar en s. k. variator och ranare. Hittills har variatorn varit anordnad att mottaga en vrideffekt fran branslemataren och variatorn innefattade en installbar mekanism for installning av ett literpris, som visades genom ett eller flera fonster i pumpen. Den. fran mataren mottagna vrideffekten passerade genom variatorn for manovrering av en raknare, som indikerade antalet angivna liter bransle. En andra, fran variatorn utgaende vrideffekt manovrerade en. andra ranare, som indikerade det totala priset, beraknat pa matarens ineffekt och installningen for literpriset. SO- vOltotala antalet som det totala priset vi- sades genom fonster i holjet. Dylika matare innefattade Oven raknare for angivande av den totalt fran pumpen forsalda mangden samt voro utrustade med mekanismer for noll-installning av indikeringarna betraffande det totala literantalet och det totala priset av en forsaljning. Dessa vanliga mekanismer omnamnas ddrfor att enligt uppfinningen variatorer av vanlig typ anvandas, och raneanordningarna i storsta allmanhet Oro av normal typ med narmare beskrivna avvikelser i mekaniskt avseende. Fig. 1 shows the upper part 2 of the usual housing of a petrol pump, which in general generally comprises a housing with a petrol pump and drive motor arranged therein as well as a petrol feeder. In the upper part of such a casing Or a razor is arranged, which comprises a so-called variator and robber. Hitherto, the variator has been arranged to receive a torque from the fuel feeder and the variator included an installable mechanism for installing a liter price, which was displayed through one or more windows in the pump. The. The torque received from the feeder passed through the variator for maneuvering a rake, which indicated the number of liters of fuel specified. A second torque output from the variator maneuvered one. other robbers, who indicated the total price, calculated on the power of the feeder and the installation for the price per liter. SOVOLTOTAL NUMBER as the total price was displayed through windows in the cover. Such feeders also included ovens for indicating the total quantity sold from the pump and were equipped with mechanisms for zero installation of the indications concerning the total number of liters and the total price of a sale. These usual mechanisms are renamed because, according to the invention, variators of the usual type are used, and the robber devices in general are of concern of the normal type with deviations described in more detail in mechanical terms.

Bensinpumpen enligt uppfinningen har i huvudsak det vanliga utseendet och Or, sasom antydes i fig. 2, forsedd med en grundkomponentpump 4, som p0 vanligt salt drives medelst en motor och som Or anordnad att genom ledningen 6 matas med del grundkomponenten bildande branslet fran en forradstank. Pa vanligt satt Or grundbranslepumpen 4 forsedd med en fiSrbiledning 8, i vilken en avlastningsventil 10 Or anordnad, varigenom grundbranslepumpen kan fortsatta att arbeta Oven sedan fyllningsslangens utlopp tillslutits, genom att grundbranslet cirkulerar genom ventilen 10 fran pumpens utlopp till dess inlopp. Branslet utmatas fran grundbranslepumpen genom ett nor 12, som avgiver bensinen genom grundbranslemataren 14, vii-ken kan vara av normal typ. Denna matare angiver exakt den darigenom utmatade mangden bensin med den av myndigheterna foreskrivna noggrannheten. Fran mataren 14 fly-ter grundbranslet genom ett ror 18 med en backventil 16. The petrol pump according to the invention has essentially the usual appearance and Or, as indicated in Fig. 2, is provided with a basic component pump 4, which on ordinary salt is driven by a motor and which Or is arranged to be fed through the line 6 with the basic component forming fuel from a storage tank. . Normally, the base fuel pump 4 is provided with a guide line 8, in which a relief valve 10 is provided, whereby the base fuel pump can continue to operate even after the filling hose outlet is closed, by the base fuel circulating through the valve 10 from the pump outlet to its inlet. The fuel is discharged from the base fuel pump through a no 12, which discharges the gasoline through the base fuel feeder 14, which may be of the normal type. This feeder indicates exactly the amount of petrol discharged thereby with the accuracy prescribed by the authorities. From the feeder 14 the base fuel flows through a tube 18 with a non-return valve 16.

En pump 22 for tillsatsbranslet tillfores detta bransle fran en tank genom en riirledning — 17, 503 —3 20. Pumpen 22 kan vara av samma typ som grundbranslepumpen och är forsedd med en forbiledning 24 med en avlastningsventil 26. A pump 22 for the additive fuel is supplied to this fuel from a tank through a line - 17, 503 - 3 20. The pump 22 may be of the same type as the base fuel pump and is provided with a bypass 24 with a relief valve 26.

Tillsatsbranslepumpen 22 utmatar tillsatsbransle genom en ledning 28 till en matare 30, som kan vara av samma typ som grundbranslemataren. Utmatning fran mataren 30 sker genom en ledning 32, i vilken en backventil 34 ãr anordnad. The auxiliary fuel pump 22 discharges auxiliary fuel through a line 28 to a feeder 30, which may be of the same type as the base fuel feeder. Discharge from the feeder 30 takes place through a line 32, in which a non-return valve 34 is arranged.

Tillforseln av grundbranslet och tillsatsbranslet fran ledningen 18 resp. 32, regleras med hjalp av ventiler 36 resp. 38, varifran de flyta genom ledningar 37 resp. 39, vilka komma att beskrivas narmare har nedan. The supply of the basic fuel and the additional fuel from line 18 resp. 32, is regulated by means of valves 36 resp. 38, from which they flow through lines 37 resp. 39, which will be described in more detail below.

De heldragna, med pilar forsedda forbindelselinjerna i fig. 2 angiva mekaniska forbindelser och visas i storre konstruktiv detalj i fig. 1, varvid dock vissa av forbindelserna Aro interna delar i har nedan beskrivna apparater. Grundbranslemataren 14 Or forbunden med grundbranslevariatorn 44 genom mekaniska forbindelseeelement 40 och 42. Dessa forbindelseelement Oro av vanlig typ och variatorn innehaller de vanliga installbara organen for inforande av ett pris och astadkommande av en uteffekt vid 48 till en i sin helhet med 46 i fig. 1 betecknad totalsammanraknare, som innefattar olika element, vilka vart och ett angivas genom block i fig. 2. Grundbranslemataren tillfor vid 50 en. in-of fekt till differentialen 52. The solid, arrowed connecting lines in Fig. 2 indicate mechanical connections and are shown in greater constructive detail in Fig. 1, however, some of the connections Aro internal parts i have apparatus described below. The base fuel feeder 14 is connected to the base fuel variator 44 by mechanical connectors 40 and 42. These connectors are of the conventional type and the variator includes the usual installable means for introducing a price and providing an output power at 48 to a total of 46 in FIG. designated total aggregator, which comprises various elements, each of which is indicated by blocks in Fig. 2. The basic fuel feeder is supplied at 50 a. input to the differential 52.

Tillsatsbranslemataren 30 astadkommer vid 51 en utgaende yrideffekt, som over fOrbindelsen 56 matar en tillsatsbranslevariator 58, I vilken literpriset for tillsatsbranslet infores for erhallande av en uteffekt vid 64 motsvarande tillsatsbranslets totala pris. Uteffekten Iran tillsatsbranslematarcn 30 tillfOres differentialen 52 Over en forbindelse 60. Variatorerna 44 och 58 kunna vara av normalt utRwanda och behOva icke beskrivas 1 detalj. The auxiliary fuel feeder 30 produces at 51 an output noise effect, which over the connection 56 feeds an auxiliary fuel variator 58, into which the liter price of the auxiliary fuel is introduced to obtain an output power at 64 corresponding to the total price of the auxiliary fuel. The output of the auxiliary fuel supply 30 is supplied to the differential 52 via a connection 60. The variators 44 and 58 may be of normal nature and need not be described in detail.

De fran grundbranslemataren och tillsatsbranslemataren harledda vrideffekterna motsvarande resp. mangder av grundbransle och tillsatsbransle inmatas i en differential 52, som summerar de IA& mangderna och avgiver en uteffekt till totalmangdra.knaren 62. The rotational effects from the basic fuel feeder and the additional fuel feeder have the corresponding corresponding quantities of base fuel and auxiliary fuel are fed into a differential 52, which sums the IA & quantities and delivers an output power to the total quantity extractor 62.

Differentialen 66 mottager uteffekterna frau grundbranslevariatorn 44 och tillsatsbranslevariatorn 58, vilka uteffekter representera priserna for de avgivna mangderna grundbransle och tillsatsbransle. Dessa priser adderas i differentialen ()eh tillfOras prisraknaren 68. Den avgivna totala litermangden och totalpriset visas genom Hester i branslepumpen (fig. 1) och dessutom visas literpriset for grundbranslet vid 70 och literpriset for tillsatsbranslet vid 72. Dessa bada indikeringar forklaras givetvis genom en lamplig text pa pumpens yta. The differential 66 receives the outputs from the base fuel variator 44 and the auxiliary fuel variator 58, which outputs represent the prices for the quantities of base fuel and auxiliary fuel delivered. These prices are added in the differential () eh supplied to the price calculator 68. The delivered total liter quantity and the total price are shown by Hester in the fuel pump (fig. 1) and in addition the liter price for the base fuel is shown at 70 and the liter price for the additive fuel at 72. These two indications are of course explained by a light text on the surface of the pump.

Endast ovan angivna indikeringar behOya vara synliga for kunden, som Or intresserad av grundbranslepriset, tillsatsbranslepriset, det totala literantalet och totalpriset. If all sarskilda bensinkvaliteter erbjudas, kan Oven en indikering av kvalitetsklassen forekomma, men detta Or i regel obehovligt. Av beskrivningen av mekanismen for installning av kvalitetstypen kommer att framga, att indikering kan givas pa nagot av manga mojliga satt. Only the above indications should be visible to the customer, who are interested in the basic fuel price, the additional fuel price, the total number of liters and the total price. If all special petrol qualities are offered, an indication of the quality class may occur, but this is usually unnecessary. From the description of the mechanism for installation of the quality type it will be seen that indication can be given in any of many possible ways.

Alit som hittills framhallits i stOrsta allmanhet, avser det salt, pa vilket kunden un- derrattas om bensinmangden och totalpri- set. Han underrattas saledes om summan ay de av grundbransle- och tillsatsbranslematar- na uppmatta mangderna och han kommer att betala det pris, som Or summan av priserna for det grun.dbransle och tillsatsbransle, som han faktiskt erhaller. Den mekanism, som stracker sig fran ineffekterna 40 och 54 till raknarna 62 och 68 kan vara av tidigare beskriven typ. Mekanismen mojliggor atminstone i for praktiken tillracklig approximation en bestamning av andelarna av grundbranslet och tillsatsbranslet i enlighet med eLt fOrutbestamt forhallande. All that has hitherto been emphasized in the greatest publicity refers to the salt on which the customer is informed about the amount of petrol and the total price. He will thus be informed of the sum of the quantities supplied by the basic fuel and ancillary fuel feeds, and he will pay the price which Or sums up the prices for the basic fuel and ancillary fuel which he actually receives. The mechanism extending from the inputs 40 and 54 to the racks 62 and 68 may be of the type previously described. The mechanism makes it possible, at least in an approximation sufficient for practice, to determine the proportions of the base fuel and the additive fuel in accordance with a predetermined ratio.

Grundbranslemataren och tillsatsbranslemataren astadkomma Over mekaniska forbindelser 71 resp. 78 ineffekter till motsvarande vaxellador 80 resp. 82, vilka i sin fur Astadkomma ineffekter till en differential 84, som Over mekaniska fiirbindelser 86 styr grundbransleventilen 36 och tillsatsbransleventilen 38. Namnda organ komma nu att beskrivas I detalj. The basic fuel feeder and the additional fuel feeder provide Over mechanical connections 71 resp. 78 input effects to the corresponding gearboxes 80 resp. 82, which in their effect provide inputs to a differential 84, which over mechanical connections 86 controls the base fuel valve 36 and the auxiliary fuel valve 38. said means will now be described in detail.

Harigenom erhalles en kopplingsanordning i det att axeln. 184 Or kopplad med hjulsegmentet 180, nar tappen 188 Or i ingreppslage mellan tapparna 182. Nar handtaget 152 Or i sitt normala upplyfta lage, befinner sig axeln 150 i sitt ytterlage medurs, sett frau apparatens framsida, och nyss beskrivna kopplingsanordning Or frikopplad. As shown in Fig. 6, the shaft 156 is provided with a screw wheel drive 178, which Or engages a wheel segment 180 (Fig. 8), provided with a pair of radially projecting pins 182. The segment 180 Or is mounted on an axle! 184, on which a part 186 is wedged, which carries a conical pin 188, arranged for engagement between the pins 182. The part 186 is provided with a track extending around the circumference for engagement with segment parts, which are supported by the fork-shaped spirit of a long 190, which is pivotally mounted to an arm 192, which is suspended by the shaft 150. Thereby a coupling device is obtained in that the shaft. 184 Or connected to the wheel segment 180, when the pin 188 Or in engagement position between the pins 182. When the handle 152 Or is in its normal raised position, the shaft 150 is in its outer layer clockwise, seen from the front of the apparatus, and the coupling device just described Or disengaged.

A gear 202 (Fig. 6), which Or is attached to the shaft 104, engages a gear 204, which Or is rotatable about the shaft 106 and which carries bearing pins for the planet gears 206, which Or is engaged with the sun gear 208, which Or is attached to the shaft 106. The planet gears 206 are integral with smaller gears 210, which are engaged with a central gear 212, to which a gear 214 is attached, which is engaged with a gear 216 mounted on the shaft 198. An even spring is actuated. pin 218 is supported by a part 220 attached to the shaft 198 and by engaging a shallow opening in the gear 216 forms a resilient drive connection between the gear 216 and the shaft 198. Under normal operating conditions the gear 216 can be considered attached to the shaft 198, but the spar device Or arranged to yield when clamping to prevent damage by interrupting the connection between the gear and the shaft.

Sasom visas i fig. 5 och 6, forbinder en kugghjulsserie 222, 224 och 226 axeln 88 med den utgaende forbindelsen 228 (fig. 6), som leder till raknaren, sasom visas i fig. 1. Detta Or endast ett lampligt salt att astadkomma en forbindelse fran grundbranslemataren 14 till raknaren. As shown in Figs. 5 and 6, a series of gears 222, 224 and 226 connect the shaft 88 to the output connection 228 (Fig. 6), which leads to the rake, as shown in Fig. 1. This Or only a suitable salt to provide a connection from the base fuel feeder 14 to the shredder.

En tapp 230 (fig. 13) stracker sig nedat Iran armen 200 och Or i ingrepp med en slits i en. arm 232, som fir fastgjord vid en axel 234, vilken uppbar de fjaderpaverkade ventilorganen 236 och 238, fOrsedda med cylindriska ytor i ingrepp med innervaggen av en borrning i ett ventilhus 239. Oppningar 240 och 242 (fig. 12) samverka med ventilerna 236 resp. 238 for reglering av flodet av branslebestandsdelarna. Grundbranslet intrader i kammaren 244 i ventilhuset genom forbindelsen 248 och tillsatsbranslet intrader i kammaren 246 genom forbindelsen 250. De hada kamrarna Oro skilda genom en vagg 247. Oppningen 240 Or i forbindelse med en kanal 252 (fig. 11 och 12), varifran branslet strommar in i ett synglas 254, i vilket plastkulor 256 kunna vara anordnade for indikering av pa, gaende stromning. Fran synglaset 254 striimmar branslet genom kanalen 258 till roret 260, som Or anslutet till det inre roret 262 (fig. 14) av en pafyllningsslang. Oppningen 242 fir direkt forbindelse med ett synglas 264, som avenledes innehaller plastkulor och fran vilket branslet strommar genom kanalen 266 och forbindelsen 268 in i det yttre roret av pa, fyllningsslangen. Sasom visas sarskilt i fig. 1, har pafyllningsslangen en konstruktion, vid vilken munstycket 272 regleras av en ventil 274, som manovreras medelst en havarm 276 for reglering air flodet till utloppet 278. Det inre roret 262 Or forbundet med ett ror 280, som mynnar vid 282 nara intill ventilen. Tydligen sker icke nagon blandning av de hada komponenterna, vilka flyta genom Oct inre roret 262 resp. det yttre roret 270, forran de kommit fram till stallet 282. Eftersom delta Jigger nara intill ventilen 274, innehaller — — slangen icke flagon namnvard mangd av blandade komponenter, varfor en palyllning I huvudsak Iran borjan sker med det onskade blandningsforhallandet av komponenterna. A pin 230 (Fig. 13) extends down the Iran arm 200 and Or engages a slot in one. arm 232, which is attached to a shaft 234 which supported the spring-actuated valve members 236 and 238, provided with cylindrical surfaces in engagement with the inner cradle of a bore in a valve housing 239. Apertures 240 and 242 (Fig. 12) cooperate with the valves 236 and 236, respectively. . 238 for regulating the flow of industry components. The base fuel enters the chamber 244 in the valve housing through the connection 248 and the additive fuel enters the chamber 246 through the connection 250. The had chambers are separated by a cradle 247. The opening 240 Or in connection with a channel 252 (Figs. 11 and 12), from which the industry flows into a sight glass 254, in which plastic balls 256 may be arranged to indicate ongoing flow. From the sight glass 254, the fuel flows through the channel 258 to the tube 260, which is connected to the inner tube 262 (Fig. 14) by a filling hose. The opening 242 communicates directly with a sight glass 264, which in turn contains plastic balls and from which the fuel flows through the channel 266 and the connection 268 into the outer tube of the filling hose. As shown separately in Fig. 1, the filling hose has a structure in which the nozzle 272 is controlled by a valve 274 which is operated by means of a lever 276 for regulating the air flow to the outlet 278. The inner tube 262 is connected to a tube 280 which opens at 282 near the valve. Apparently no mixing of the hada components takes place, which flow through the Oct inner tube 262 resp. the outer rudder 270, before they arrive at the stable 282. Since the delta jigger is close to the valve 274, the hose does not contain a large number of mixed components, for which a pilling is mainly performed in Iran with the desired mixing ratio of the components.

Driftsprincipen fir apparaten bestir dari, att vid avgivande av en blandning av bestandsdelarna kugghjulen 100 och 102 aro i ingrepp med motsvarande kuggelement pa de koniska kugghjulen 108 och 110 (fig. 6). Ineffekterna Iran matarna over forbindelserna 74 och 78 driva axlarna 104 och 106 i enlighet med den valda installningen och diff erential-kugghjulsforbindelsen 204-212 lamnar en uteffekt, som fir lika med differensen i axlarnas 104 och 106 vridningsvarv. Om flodet genom mfitarna ar sadant, att denna uteffekt ãr lika med noll, innebar detta, att flodena genom de hada matarna sta i ett forhallande, som motsvarar kugghjulens install-fling. Om Om flodena ickc aro i detta forhallande, erhalles en uteffekt frail differentialkugghjulsforbindelsen, som astaclkommer en omstfillning av ventilerna 236 och 238 Mr okning av flodet av den ena komponenten och minskning av floclet av den andra for uppnaende av det onskade forhallandet. Jamvikt skulle uppnas i detta fall, nar flodena uppvisa det genom kugghjulsinstallningen bestamda forhallandet. I regel sker viss pendling kring det exakta jamviktslaget. Det bor dock observeras, att bortsett fran den mojligheten, att sliming upptrader i matarna, de avgivna mangderna i huvudsak integreras, och Over en utstrackt utmatningstid kommer felet i proportionsbestamningen endast att uppga till det varde, som heron pt omstallningen fran en foregaende ventilinstallning till i huvudsak den instfillning, som reglerar den korrekta installningen av blandningsforhallandet. Nagot kumulativt fel upptrader icke. The operating principle of the apparatus consists in that when dispensing a mixture of the constituents, the gears 100 and 102 are in engagement with the corresponding gear elements on the bevel gears 108 and 110 (Fig. 6). The inputs Iran feeds over the connections 74 and 78 drive the shafts 104 and 106 in accordance with the selected installation and the differential gear connection 204-212 leaves an output power equal to the difference in the rotational turns of the shafts 104 and 106. If the flow through the mites is such that this output power is equal to zero, this means that the rivers through the hot feeds are in a ratio corresponding to the installation of the gears. If the rivers are not in this ratio, an output effect is obtained from the differential gear connection, which results in a reversal of the valves 236 and 238, increasing the flow of one component and decreasing the floc of the other to achieve the desired ratio. Equilibrium would be reached in this case, when the rivers exhibit the ratio determined by the gear installation. As a rule, some commuting takes place around the exact equilibrium stroke. It should be noted, however, that apart from the possibility that sliming occurs in the feeds, the amounts released are mainly integrated, and over an extended discharge time, the error in the proportion determination will only amount to the value at which the conversion from a previous valve installation to essentially the setting, which regulates the correct installation of the mixing ratio. No cumulative error occurs.

Det har omnanants, att ett tel kan upptrada till foljd av den omstandigheten, att i bor.- jan av en utportionering ventilerna kunna ha varit installda for ett belt annat blandningsfOrhallande an det onskade. Under tiden for justeringen av ventilinstallningen forekommer en avvikelse fran det onskade blandningsforhallandet. Enligt foreliggande uppfinning minskas inflytandet av detta tel genom att ventilerna for hand installas i det narmaste till det onskade laget. It has omnanants that a tel can occur as a result of the fact that at the beginning of a portioning out the valves could have been installed for a slightly different mixing ratio than desired. During the time of the adjustment of the valve installation, a deviation from the desired mixing ratio occurs. According to the present invention, the influence of this tel is reduced by manually installing the valves closest to the desired layer.

Nar mekanismen befinner sig i vila, leder handtagets frigivning till att axeln 156 fast-Mlles i ingreppslage genom ingreppet av hakpartiet 170 pa havarmen 172 mellan ett par tappar 168 (fig. 7). Omstallning av axeln 156 kan endast astadkommas genom svangning av axeln 150 med hjalp av handtaget 152. Genom axelns 150 svangning frigivas icke endast kugghjulen. 100 och 102 fran ingreppet och hakpartiet 170 frail tapparna utan fire tapparnas fullstandiga frigivning pressas genom axelns 150 vridning moturs den koniska tappen 188 (fig. 6) till ingreppslage mellan tapparna 182, varigenom axeln 184 kopplas med hjulsegmentet 180. Eftersom man kan antaga, att bortsett frail pendlingsfel, yentilerna aro i det lage, som betingas av den foregaende manovreringen och den i huvudsak motsvarar det blandningsfOrhallande, som astadkommits darvid, kommer tappen 188 att intrada i mellanrummet mellan tapparna 182 och vid dess forflyttning at hoger I fig. 6 kan axeln 184 vridas nagot genom den darvid upptradande kamverkan, varigenom en Nit justering av ventillagena uppnas. La-get for segmentet 180 kommer i det narmaste att svara mot ventilernas lage f Or korrekt avgivande av varje instant forhallande. Medan handtaget 152 halles nedtryckt, vrides knappen 154 till installningslaget for det vid nasta utportionering 6nskade blandningsforhallandet. Da denna installning utfOres, flyttas icke endast kugghjulen 100 och 102 axiellt mot det onskade laget for ingrepp med de koniska kugghjulen, utan drives aven axeln 184 fOr injustering av ventilerna 236 och 238 till lagen, vilka i det narmaste aro korrekta for den nya utportioneringen. Nan handtaget 152 darefter frigives, lases axeln 156 pa nytt och tappen 188 drages tillbaka for frikoppling av axeln 184 fran segmentet 180, och kugghjulen 100 och 102 tillatas komma i ingrepp under fjadrarnas 140 och 142 inverkan. Genom nyss beskrivna atgarder installas ventilerna 236 och 238 pa ett ungefar for hand i den for foljande utminutering erforderliga installningen, och da utminuteringen paborjas, sker endast en forhallandevis obetydlig justering av ventilerna, vilket innebar, att utminuteringen borjar i det narmaste med det ratta blandningsforhallandet. Viss injustering kommer givetvis att upptrada, men begynnelsefelet minskas betydligt. Matarna avlastas aven frau den pakanningen att i stor utstrackning behova injustera ventilerna och denna belastningsminskning nedsatter matningsf elet. When the mechanism is at rest, the release of the handle causes the shaft 156 to be locked in engagement position by the engagement of the hook portion 170 on the lever arm 172 between a pair of pins 168 (Fig. 7). Adjustment of the shaft 156 can only be effected by pivoting the shaft 150 with the aid of the handle 152. Not only the gears are released by the pivoting of the shaft 150. 100 and 102 from the engagement and the hook portion 170 of the pins without the complete release of the four pins are pressed by the rotation of the shaft 150 counterclockwise the conical pin 188 (Fig. 6) to the engaging position between the pins 182, whereby the shaft 184 is coupled to the wheel segment 180. apart from the oscillating error, the yentiles are in the position which is due to the previous maneuvering and which substantially corresponds to the mixing ratio obtained thereby, the pin 188 will enter the space between the pins 182 and when it moves higher in Fig. 6 the shaft 184 is turned slightly by the resulting cam action, whereby a rivet adjustment of the valve layers is achieved. The position of the segment 180 will almost correspond to the position of the valves for the correct delivery of each instantaneous delay. While holding down the handle 152, turn the knob 154 to the installation layer for the desired mixing ratio at the next dispensing. When this installation is performed, not only are the gears 100 and 102 moved axially toward the desired bearing engagement ring, but also the shaft 184 is driven to adjust the valves 236 and 238 to the bearings, which are substantially correct for the new alignment. After the handle 152 is subsequently released, the shaft 156 is read again and the pin 188 is retracted to disengage the shaft 184 from the segment 180, and the gears 100 and 102 are allowed to engage under the action of the springs 140 and 142. By means of the measures just described, the valves 236 and 238 are installed approximately in a manual manner in the installation required for the next minute, and when the minute is started, only a relatively insignificant adjustment of the valves takes place, which means that the minute starts almost with the correct mixing ratio. Some adjustment will of course occur, but the initial error is significantly reduced. The feeders are also relieved from the packing that to a large extent need to adjust the valves and this load reduction reduces the feed error.

Det har ovan antagits, att de hada branslekomponenterna avgivas. Automatisk drift av kugghjulsforbindelsen och differentialen upptrader endast pa detta villkor. Om daremot endast en av komponenterna skall avgivas, sker installningen for hand med endast den ena eller den andra av ventilerna 236 och 238 fullstandigt tillsluten och den andra vidoppen. For att astadkomma utminutering av endast en komponent, nedtryckes handtaget 152 med ovan beskriven pafoljd, varefter knappen 154 installes till ett lage, i vilket mellanrummet tappen 168B och nargransande tapp 168 (fig. 7) eller mellan tappen 168A och narmaste tapp 168 infores i linje med hakpartiet 170 pa havarmen 172. Under installningen kopplar tappar 182 axeln 184 till segmentet 180, varigenom axelns 156 installning flyttar den ena eller den andra av ventilerna 6— — 236 och 238 till helt slutet lage och den andra till helt 6ppet lage. Genom att handtaget 152 darefter frigives, kan hakpartiet 170 tranga in i mellanrummet mellan tapparna, men handtaget och axeln 150 kunna icke aterga till normalt lage genom att den ena eller andra av tapparna 174 och 176 farts i vagen. Genom att axeln 150 hindras fran att aterga helt, fasthallas kugghjulen 100 och 102 ur ingreppslaget och forhindras fullstandigt tillbakadragning av tappen 188. Utminuteringen sker darefter endast betraffande en komponent och kugghjulsforbindelsen är overksam, varvid det ena eller andra av kugghjulen 100 och 102 ga'r tomt. It has been assumed above that the hated industry components will be released. Automatic operation of the gear connection and differential occurs only on this condition. If, on the other hand, only one of the components is to be delivered, the installation is done by hand with only one or the other of the valves 236 and 238 completely closed and the other wide open. To minimize only one component, the handle 152 is pressed with the pawl sequence described above, after which the button 154 is installed to a position in which the gap pin 168B and adjacent pin 168 (Fig. 7) or between pin 168A and nearest pin 168 are inserted in line with the hook portion 170 on the sea arm 172. During installation, pins 182 connect the shaft 184 to the segment 180, whereby the installation of the shaft 156 moves one or the other of the valves 6-23 and 238 to the fully closed bearing and the other to the fully closed bearing. By subsequently releasing the handle 152, the hook portion 170 can penetrate into the space between the pins, but the handle and the shaft 150 cannot return to normal position by one or the other of the pins 174 and 176 being moved in the carriage. By preventing the shaft 150 from returning completely, the gears 100 and 102 are retained from the engaging stroke and complete retraction of the pin 188 is prevented. The minimization then takes place only with respect to one component and the gear connection is inactive, one or the other of the gears 100 and 102 plot.

Av ritningen framgar att oppningarna 240 och 242 aro i huvudsak rektangulara och att ventilerna ligga radiellt i linje sa att till fOljd av Oppningarnas inbordes vinkelfOrskjutning den ena oppningens tillslutning intraffar, dá den andra oppnas. Med hansyn till den automatiska driften har det i praktiken visat sig onodigt att tillampa en speciell form hos Oppningarna, men detta kan goras, om sã onskas, for att sakerstalla en annu mera exakt manuell installning av ventilerna i motsvarighet till det blandningsforhallande, pa vilket apparaten blivit installd. Det Mir emellertid framhallas, alt ventilerna icke ha nagot med nodvandighet bestamt lage i forballande till sina oppningar for uppnaende av ratt blandningsforhallande, utan att proportioneringen astadkommes medelst en anordning, som utOr en tillbakamatningsslinga genom mãtarna. Detta star i motsats till tidigare i liknande sammanhang gjorda forslag, enligt vilka bestamda ventillagen utnyttjas for proportioneringen. I dylika fall är det vasentligt, att ventilerna och oppningarna utformas och samordnas med storsta omsorg, och det liar dessutom varit nodvandigt att for erhallande av vederborlig noggrannhet vid bIandningen infora en kompensation for olika hydrostatiska nivaer hos komponenterna, for ternperaturvariationer eller dylikt. Alla sadana anordningar goras overflodiga i enlighet med foreliggande uppfinning, enligt vilken ett noggrant innehallande av blandningsforhallandet uteslutande beror pa den noggrannhet, med vilken matarna arbeta. The drawing shows that the openings 240 and 242 are substantially rectangular and that the valves are radially aligned so that due to the angular displacement of the inlets of the inlets, the closure of one opening occurs when the other is opened. With regard to the automatic operation, it has in practice proved unnecessary to apply a special shape to the openings, but this can be done, if desired, to ensure an even more precise manual installation of the valves in accordance with the mixing ratio at which the apparatus has been installed. It should be noted, however, that the valves do not necessarily have anything to pack in their openings to achieve a straight mixing ratio, without the proportioning being achieved by means of a device which emits a feed loop through the meters. This is in contrast to previous proposals made in similar contexts, according to which certain valve laws are used for proportioning. In such cases it is essential that the valves and openings be designed and coordinated with the utmost care, and it has also been necessary to introduce a compensation for different hydrostatic levels of the components, for temperature variations or the like, in order to obtain proper accuracy in mixing. All such devices are made redundant in accordance with the present invention, according to which an accurate containment of the mixing ratio depends solely on the accuracy with which the feeders operate.

Smarre avvikelser fran ett onskat blandningsforhallande kunna forekomma, framfor alit vid avgivande av sma branslemangder och till foljd av en eventuellt darvid erforderlig omstallning av ventilerna (vilket fel dock enligt ovan kan hallas vid ett litet varde). I ett sadant fall ãr anordningen sadan, att kunden endast betalar for vad han 'far. Han kan erhalla ett fran det begarda nagot avvikande blandningsforhallande mellan bestandsdelarna, men avvikelsen ãr praktiskt taget utan betydelse och skulle icke kunna upptaekas vid driften av den med bransleblandningen arbetande maskinen. Det är att marka att vid fel i anordningen, t. ex. nar en veatil hanger upp sig, skador pa kugghjulsforbindelsen undvikas genom att tappen 218 kan giva efter for frigivande av drivfOrbindelsen mellan kugghjulen och axeln 198. Om axeln 184 och ventilerna icke fran barjan installas fOr hand till det ungefarliga laget for det ratta blandningsfOrhallandet, kan det aven intraffa att vissa delar lasa sig under injusteringen, varvid ventilerna foras till nagot extremt lage. Den ungefarliga, Mr hand foretagna installningen sakerstaller dock att endast sma justeringar av ventilernas installning erfordras. Minor deviations from a desired mixing ratio may occur, rather than during the delivery of small amounts of fuel and as a result of any necessary adjustment of the valves (which error, however, as above can be kept at a small value). In such a case, the device is such that the customer only pays for what he gets. He can obtain a slightly different mixing ratio between the components from the required, but the deviation is practically insignificant and could not be detected during the operation of the machine working with the fuel mixture. It should be noted that in the event of a fault in the device, e.g. When a valve is suspended, damage to the gear connection is avoided by allowing the pin 218 to yield to release the drive connection between the gears and the shaft 198. If the shaft 184 and the valves are not installed from the start by hand to the safe layer of the steering gear ratio, it may It also happens that certain parts become loose during the adjustment, whereby the valves are led to something extremely low. The safe, Mr. hand-made installation, however, means that only small adjustments to the installation of the valves are required.
