Abstract
The invention concerns a device for the measured transferring of several liquids of the same kind, in particular a petrol pump for liquid fuels wherein the liquid extracted from a tank (8, 9, 10) using one of the pumps (5, 6, 7) allocated to the respective liquid is transferred from one of the fuel dispensers (2, 3, 4) allocated to the respective liquid whilst being measured at the same time. What is new is a common liquid measuring device (1) for the liquids with valves (13 to 18) arranged upstream and downstream forming a delivery connection from one of the pumps (5 to 7) via the measuring device (1) to the allocated fuel dispenser (2, 3, 4).

C~vices ac~r~ y to the generic terms of claim 1 are kno~n f~om ~e sbte of ~e art A fuel pump for Jifl~r~nt types of liquid fuels, such as p~trol, contains a plurali~y of ~uel dispenser~, such as deli~ ery, ~ s, which are 11tted to the end of the delive~y hose. Each of such fuel dispensers is ~ssiy~lGJ to a par~cular ~rpe of fuel and each of such fuel dispen~r~ is cor",e~ ugh a supply line to the con~, on~l;.,g supply 1~nk. I~ ed l,~ dispe.,ser and its cGr._,pon~ing supply tank, each supply line confains a ~e'r~_.r pump ànd an ssoci~tc~l measuring device for liquids. If, for exan~ple, ~ petrol pump contains ~ree delivery ~uel .Jbpensers for normal petrol, Su~er and Super Plus, *en altoy~ r three n.~ ring devi~s are in use hr types of fuel, which are basically similar. 1~ s ~ing devicos such as theso ar~ Lshre and require re calibraffon from time to ffme.

WO 98/00359 ~CT/EP97102671 any one time, whilst the other huel ~ispe- ,sers are idle. To disp~ay ~e amount of fuel trans~erred, a common display is provided It has been e~tablished, that the fuel remaining in the common liquid measuring d~vicQ ren~ains below the cGr-espo..ding calibra~on tolerance, so that it must be a;~"~ble, that sG."ao,.e, who for example draws normal petrol, also ~~ i~ves a small amount of Super petrol, which had been sel~h~ by ~e person before him. For pr~ference, a screw spindl~ anye.,.~.~t is sel~t~ as li~id measuring device, such as the one d~s_~iL~J in ~E-OS 41 42 062. The cl~rance volume ~f the two intermeshing screw spindles, one of which is oonnected to a rotational counter, is very small anJ in ~e order of about 13 cma With a t~picalrninimum amount of 51 of fuel dispensed, this amount is ~er~ore below ~e caliL~.,tiG-- toleranQ In a pr~,f~n~ ~ ..yement of the i~,~n~ , a valYe has been fi~ed d~u ,s~leam of each pump and a valvo tlas been fi~ upsl..,_.., of each fuel cl;~e,.~er. The ~No resulting amnge.~ ~ of valves, are connected in the shape of a triple-way or multi~vay valve. The c~ on li~uid measuring device is ;~ ed b~Heen ~ese valve arrangements, so ~at by sui~able sefflng of ~e of ~e 'aiple way or mul~way valv~s the liquid m~suring device is be ccl-ne~,t.3d be~een a fuel ~isp6n~er and its ~I.espondirq supply ~nk.

An electronic circuit may then ensure, ~at, to prevent ihCG- ~~cL op-raffon, ~e fuel supply is cut ofl if more ~an one delivery nozlc is used simulbneously. For such a purpose it could be arranged, that the operation d ~e manually op~r.-~l valve conta;ned in the delivery n~le ~enerat3~ an ~lecbic signal, which is taken to a solenoid and which on ~he simulla~ous arri~al of two such signals closes the upstream valves This causes in elec~ric blocking The valves contained in tlle delively nozzles could contain a non-return fundion.
wo ssroo3ss ~CT/EPg7/02671 For preference, valves could be constructed in such a manner that they only open at a ~r~d~t~rl..ined pressure, such as 08 bar, to ensure, that wllen operating more than one deli~ nozle, no liquid can e~i~ since the up~ . ., valve is chss~l.

In r~s~ of fur~er features of the liquid ~neasurement device, reference is made to C)E 41 42 ~62. The con~ersion of te2t values and tl~e display of ~alues of the example correspond to DE 41 52 062, whereby for WO 3~tU0359 rCT~t~ r/02671 each completed supply link individual cal,~r~tion and conversion parameter for volume and price display are provid~d on the co.,.,~Gr, d;splay unit.

With valves 16, 17, 18 clc66~1, pressures in the delive~y hose falls below~e ~--issiGn pressure so ~at ~e manually C6~ valves contained in the delivery nozles remain closed.

Claims (9)
1. Device for the metered transfer of several but similar liquids, especially a fuel pump for liquid fuels, whereby the liquid supplied from a supply tank (8, 9, 10) by means of a corresponding pump (5, 6, 7) is delivered to the associated fuel dispenser (2, 3, 4) whilst simultaneously determining the fuel volume, characterised by a common liquid measuring device (1) in the form of a screw spindle arrangement for the fluids, fitted with upstream and downstream valves (13 to 18) to provide a supply link at any one time from one of the pumps (5 to 7) through the measuring device (1) and to the corresponding fuel dispenser (2, 3, 4).
2. Device according to claim 1, characterised in that the clearance volume of the liquid measuring device (1) is less than the calibration tolerance permissible for liquids.
3. Device according to claim 1 or 2, characterised in that the clearance volume of the liquid measuring device (1) is less than 20 cm3.
4. Device according to one or more of the previous claims, characterised in thatupstream and downstream of the liquid measuring device (1) a three-way or muti-way valve arrangement (11, 12) has been inserted.
5. Device according to one or more of the previous claims, characterised in thatvalves (13, 14, 15) of the downstream multi-way arrangement (11) are interconnected in pairs with valves (16, 17, 18) of the upstream multi-way arrangement (12).
6. Device according to claim 5, characterised in that the downstream valves (13, 14, 15) are non-return valves.
7. Device according claim 5 or 6, characterised in that the downstream valves are associated with the corresponding delivery nozzle (2, 3, 4).
8. Device according to one or more of the previous claims, characterised in thatthe valves contained in the delivery nozzles (2, 3, 4) are manually operated and are associated with an electric signal generator which supplies a valve operating signal to an electronic circuit.
9 Device according to one or more of the previous claims, characterised in that the electronic circuit will close all upstream valves (16, 17, 1 8) if more than one delivery nozzle (2, 3, 4) is activated.
