As can be seen in particular from Figures 1 to 5,

There is a fuel _{dispensing device, which comprises an embodiment:} form of a counter according to the invention, from a pair of motor-driven pumps 12 for delivering individual types of fuel to a nozzle, not shown, via a proportional valve 14 and a pair of measuring devices 16 for measuring the individual types of fuel . ^ The outputs of the measuring devices are from a differential. 2o combined to drive a suitable mixing gear 24 depending on the total amount of fluid dispensed. The outputs of the mixing gear 24 and one of the measuring devices 16 are compared with one another by means of a subtracting differential 26 in order to control the proportioning valve 14 and thus determine the ratio of each type of liquid as a function of the setting of the mixing gear 24.

W The counter includes a variator 3o and a cost

r-egister J2, which is driven by the variator, to 'To register the cost of the fuel dispensed as a function of a price per unit volume, wherein this price is fixed by the setting of the variator. The cost register is preferably in more common use Type can be reset before the start of each fuel delivery.

1Q9818 / U79

The variator ° consists of a unitary rotor or such a pulse disk 34 which is driven by the measuring devices 16 via the differential 2o and a suitable gear 35. Furthermore, a plurality of elongated, calibrated radially extending output heads 36, 37 and 38 are provided, which are angularly spaced from one another around the axis of rotation of the disk 34. An output head is provided for each of the three lowest digits of a four-digit range for the price per unit volume of the variator. It can be set depending on the desired price per volume unit. If, for example, a three-digit price per volume unit of 32.9 (for example 32.9 cents per gallon) is to be set, the header 36 for the "tenths" or for the lowest digit is set to "9", the header JJ for the " One "or the middle digit is set to" 2 "and finally the head 38 for the" tens "or the highest digit is set to" 3 ".

As shown in Figures 2 and 3, a number of four are radial aligned lamps 39 to 42 in each output head 36 ™

with the three rows of radially aligned lamps. are arranged. Accordingly, the masks overlap with the pulse disk 34 and the associated row of lamps. Fifteen transparent openings or pulse selectors 54 are arranged on the dials 5o and 51 for the "tenths" and "ones", namely in four concentric selection circles 56 to 59 * which are tangent to the pulse actuator circles 44 to 47, respectively. The dial 52 for the “tens”, however, has 32 transparent openings or pulse dials 54 which are arranged in their four W concentric dialing circles 56 to 59.

The impulse actuator circuits 44 to 47 on the impulse disc 34 are each provided with 1, 2, 4 and 8 impulse actuators 43 in order to give the impulse actuator circuits respective values of 1, 2, 4 and 8. The pulse actuators 43 are arranged at the same angular distance of 24 °, and the heads J> 6 to 38 enclose such an angular distance with one another that only one pulse actuator 43 is aligned with a lamp at any one time. For example, the heads 36 to 38 can maintain an angular spacing of 80 °, so that one of the pulse actuators 43 is aligned with one of the lamps after each rotation of the disk 34 through 8 °. Alternatively, the pulse actuators 43 can be angularly distributed within a sector (for example a 75 ° sector) of the disk

A photoelectric scanner 70, preferably comprised of a single photoelectric cell as shown in FIG. 3, is aligned in each output head with the associated row of lamps 39-42 on the opposite side of the pulse dial 34 and the associated dial. Each photoelectric scanner is accordingly arranged so that it can be actuated by any pulse operator 43 on the pulse disk 34 in order to generate a track of spaced apart electrical pulses. The number of such pulses per revolution of the pulse disc 34 can range from zero to fifteen, depending on which, if any, of the pulse actuator circuits 44 to 47 are operated thereby ^? ** ·!]! ¹ that a selection opening 54 is aligned with an associated lamp 39 to 42.

dialing stations lying one above the other on the disks 5o, 5I arise which respectively represent the values 0 to 9 in succession according to FIG. 2B, and that 16 in the same way Angular distance to one another arranged dialing stations of the disk 52 arise, which according to FIG. 2C in succession each represent the values O to I5. Since the available pulse range goes from 0 to I5 for a single revolution, the dial is 52 for the output head 38 of the highest point with a Area of Otts 15 provided so that the price per Vo- * · Lumen unit in a price range between 000.0 and

159.9 can be set. The pulse selectors 54 of the opening circles 56 to 59 in the disks 50 to 52 thus each have the valences 1, -2,4 and 8, land they "are arranged on the dialing circles in such a way that they emit the valency associated with each dialing station. The number of The pulses generated by each scanner 70 for each revolution of the disk 54 therefore depend on the angular setting of the associated dial and correspond to ψ the total value of the pulse selectors 54 at the receiving station.

The disks 5o to 52 take one in the drawing Location of their dialing stations "9", "2" and "3" respectively cooperate with the output heads 36 to 38. Two selection openings 54 of the disk 50 are also aligned
