Abstract

An apparatus for automatically limited delivery of a flow of liquid, e.g. gasol in its liquid phase, from a store (1) provided with pressurizing means (3) to a tank (2), e.g. a vehicle tank. The delivery takes place via a supply line (4) connectable to a tank inlet line (7). A non-return valve (30) is disposed in or downstream of a connection means (6) for the supply line in the tank inlet line. An overfill monitor (8 - 10) breaks off the delivery by closing a filling valve (10). The filling valve is situated down-stream of the non-return valve and implemented with a constricted bypass passage affording, in the closed position of the valve, pressure equalizition between the inlet and outlet of said valve.

Figm 3 är ett funktionsschema som illustrerar sam- verkan mellan anordningens komponenter.Fig. 3 is a functional diagram illustrating the interaction between the components of the device.

Den i fig, 1 schematiskt visade anordningen är in- rättad att från ett förråd 1 av gas i vätskefas ombesörja en automatiskt begränsad tillförsel av ett flöde av gasen till en tank 2. Tanken 2 kan vara anordnad som drivmedels- tank i ett fordon, varvid gasen utgöres av motorgas, före- trädesvis kommersiell butan eller propan eller blandningar därav. Förrâdet 1 är därvid förlagt till en mack och ut- rustat med ett tryckstegringsorgan 3 samt (icke visade) flödesmäcande utminuteringsorgan för motorgasen i vätska- fas. vätskan ledes via en matarledning 4, som i ett av- slutande parti utgörs av en slang med en tankpistol 5 i sin ntloppsände. Tankpistolen 5 är kopplingsbar till ett anslut- ningsorgan 6 i uppströmsänden av en tankinloppsledning 7.The device shown diagrammatically in Fig. 1 is arranged to provide from an storage 1 of gas in the liquid phase an automatically limited supply of a flow of the gas to a tank 2. The tank 2 can be arranged as a fuel tank in a vehicle, wherein the gas consists of motor gas, preferably commercial butane or propane or mixtures thereof. The supply 1 is then located in a gas station and equipped with a pressure boosting means 3 and (not shown) flow-reducing minimizing means for the motor gas in liquid phase. the liquid is led via a supply line 4, which in a closing portion consists of a hose with a tank gun 5 at its discharge end. The tank gun 5 can be connected to a connecting member 6 at the upstream end of a tank inlet line 7.

En backventil 30 är anordnad i anslutningsorganet strax nedströms om detta i tankinloppsledningen 7.A non-return valve 30 is arranged in the connecting means just downstream thereof in the tank inlet line 7.

At the same time, the now closed switch 13, likewise via the electronics 11, causes the refueling valve 10 to open, so that refueling can take place. Suitably the resistor 12 and the level indicator 20 are also activated.

Pig, 3, som avser att illustrera i första hand uppfinningens tillämpning vid tankning av motorgas i ett fordons drivmedelstank, visar vidare att brytaren 13 är anordnad i en krets 14 som även uppvisar ett relä 15. När donets startmotorkrets 16 (med startmotorn 17), varigenom fordonet ej kan startas så länge tankningstryck kvarstar på brytaren 13, Fordonet är enligt g. 3 också utrustat med en strömställare utgörande väl re 18 för val mellan bensin- ja drift, läge B, och gasoldrift, läge G. När läget G valts är, som synes, samtliga PTC-motstånden 8, 9 och 12 aktiverade för att indikera vätskenivån i tanken 2, förutsatt aLt ocksa serie med väljaren 18 anordnade tändningslàset 19 av läge T. Mätresultatet det i konventionellt slag är inställt i uttages via elek“ronikdonen 11 till níväindikatorn 20.Fig. 3, which is intended to illustrate primarily the application of the invention when refueling engine gas in a vehicle's fuel tank, further shows that the switch 13 is arranged in a circuit 14 which also has a relay 15. When the device's starter motor circuit 16 (with the starter motor 17), whereby the vehicle can not be started as long as refueling pressure remains on the switch 13, The vehicle is according to g. 3 also equipped with a switch constituting well re 18 for selection between petrol and operation, position B, and gasoline operation, position G. When position G is selected is , as can be seen, all the PTC resistors 8, 9 and 12 are activated to indicate the liquid level in the tank 2, provided that the ignition lock 19 of position T is also arranged in series with the selector 18. The measuring result it is conventionally set in is taken out via the electronics 11 to the nine indicator 20.

Vid körning på motorgas matas sålunda den elektro- ntrustningen med spänning från tändningslåset 19 över fä jaren 15, varvid såväl givarens motstand 8, 9, 12 som nivaindikatorn 20 är aktiverade, däremot ej de elektronik- organ, som bringar tankningsventilen 10 att öppna.When driving on engine gas, the electron equipment is thus supplied with voltage from the ignition lock 19 over the vessel 15, whereby both the sensor resistance 8, 9, 12 and the level indicator 20 are activated, but not the electronic means which cause the refueling valve 10 to open.

Tankningsventilen 10 är, som framgår av tig. 1, placerad nedströms backventilen 30 i tankinloppsledningen 7, Den är, som visas i fig. 2, utförd med en förblgångs- 21 som i ventilens stängda läge erbjuder trycket- å (D 1.: l-'J m :Ü s” .entilens inlopp 22 och utlopp 23.

Ventilkroppen är försedd med ett ankare 28 som är påverkbart medelst en spole 29.The refueling valve 10 is, as shown in FIG. 1, located downstream of the non-return valve 30 in the tank inlet line 7.

Normalt innebär detta att pumpen stannar eller shuntas, varvid räkneverket stannar, och att man sedan släpper greppcL Jm tankyiatoiens avtryokare, så att tankpietolenn ventil utünger och förbindelsen med anslutningsorganet 6 kan brytas genom av- lägsnande av tankpistolen.The pre-flow passage 21 is so dimensioned that, at the pressure normally present in the supply line H during refueling, it produces such a rapid equalization of pressure that the refueling valve 10 is able to open within about 5 seconds after the supply line tank gun 5 is connected to the connecting member. 6. In other words, Betta is a dimensioning basis that requires a certain minimum spaciousness of the passage of the bypass passage, ie. a certain maximum permissible pressure drop flowing across the passage. A requirement in the opposite direction, which the passage mdutc satisfies, is requested in that it must be so narrow, i.e. offer such a large pressure number that the flow-measuring discharge means of the storage when closing the refueling valve bring out of operation. Normally this means that the pump stops or is shunted, whereby the counter stops, and that the gripper of the tankyiatoi is then released, so that the tank pistol valve expires and the connection to the connecting means 6 can be broken by removing the tank gun.

En lämplig vidd på det parti av förbigångspassagen Kl som n;pvl,Lr minsta genomströmningstvärsnittet är, för motor- gas: en diameter av 0,5 - 1 mm, företrädesvis eza 0,8 mm.A suitable width on the portion of the bypass passage K1 which n; pvl, Lr is the smallest flow cross-section is, for motor gas: a diameter of 0.5 - 1 mm, preferably eza 0.8 mm.

Förbigàngspassegens 21 tryckfall och backventilens 30 e 1;' kraft kan vara så avvägda att backventilen 30 stänger, när tankningsventilen 10 stänger, varigenom gasför- 3 .usten mid avlägsnande av tankpistolen nedbringas till ett ECrni¿àngapassagen_21 behöver icke nödvändigtvis vara nad i ventilkroppen 27 utan kan exempelvis vara för- ilhuset BM eller till en (icke visad) fri- v en* -nantledning. I de båda sistnämnda fallen kan den Ãghet inrättas injusterbar medelst något enkelt ventilorgan, t.ex. en som nälventil utförd ställskruv.The pressure drop of the bypass passage 21 and the check valve 30 e 1; force may be so balanced that the non-return valve 30 closes, when the refueling valve 10 closes, whereby the gas leakage during removal of the tank gun is reduced to an inlet passage_21 need not necessarily be present in the valve body 27 but may for example be the pre-housing BM or a (not shown) free- v a * -nant line. In the latter two cases, the unit can be arranged adjustable by means of some simple valve means, e.g. an adjusting screw made as a needle valve.

Anordningarna för att Iorhindra start eller för- flyttning av fordonet under tankning kan vara av annat 7... slag än vad som beskrivits. Sålunda nan motorns tändninge- krets och/eller annan krets; som styr motorns startande eller fordonet förflyttning påverkas, när den tryckkäns- s liga brytaren 13 eller något annat tankningstryckets före- konst eller tankpistolens 5 förefintlighet i anslutnings- organet 6 avkännande don anger, att förbindelse med gas- förràdet 1 upprättatso förni_5ngspassage utrustade tankningsven- tilen behover ej heller vara en magnetventil, utan även andra slafi eller indirekt elektriskt styrda ven- tiler kan användas.The devices for preventing the start or movement of the vehicle during refueling may be of a different 7 ... type than that described. Thus nan engine ignition circuit and / or other circuit; which controls the starting of the engine or the movement of the vehicle is affected when the pressure-sensitive switch 13 or some other pre-pressure of the refueling pressure or the presence of the refueling gun 5 in the connecting means 6 sensing means indicates that a connection to the gas supply 1 has been established. does not need to be a solenoid valve, but other other or indirectly electrically controlled valves can also be used.
