Dispenser for liquids

The invention relates to a dispensing device for liquids, especially propellants »with a measuring device for measuring the dispensed Liquid quantity and with at least one controlled by the measuring device Advertisement*

Such dispensing devices are mostly used to draw off liquid fuels based on carbon-hydrogen in the tanks of vehicles required »which is operated by an internal combustion engine will »The dispensers generally have one through one Volume meter for the dispensed liquid operated display to monitor the amount of the tapped liquid during the dispensing process itself To indicate fuel! usually a second advertisement is planned «, which also continuously displayed the price of the amount of liquid drawn

So far, the displays have been operated mechanically, which has a number of disadvantages. One such disadvantage is in particular the difficulty in adapting the spatial position of the driving and driven components to one another, and electrical drives for the displays have already been proposed use. The use of electrical actuation systems for the displays is, however, disadvantageous because it creates a risk of fire that requires the electrical components to be extremely safe against ignition sparks. This solution is therefore very useful

Based on this, the invention has set itself the task of providing a dispensing device without mechanical drive transmission means for create the displays and without using electrical systems © in ©

The dispenser illustrated in Figure 1 has a housing 20 in a generally rectangular shape when viewed from the front. The housing 20 stands on a base 21 on which a quantity measuring device 22 and a pump, not shown here, driven by an electric motor, are arranged, the pump serving to convey the liquid to be tapped from a storage tank into the quantity dispenser 22. On the upper side of the housing 20 a horizontal ¹ pivot arm 24 is attached, at one end of which one side of a filling hose 25 is attached, while at the other end of the pivot arm 24 there is a holding device for a tap 26, which is connected to the other side of the filling hose 25 is connected) thus the tap 26 can be hung on the horizontal swivel arm 24 when it is not in use , the horizontal arm located line 28 connected let · This in turn leads to the input side · de "FUnoouauehs 25. ■

The quantity measuring device SS has an output shaft 35 “the one air pulse generator 36 drives its air pulses for control the drive of the quantity display 32 and the price display 33 are used. These themselves are driven by an air-driven actuator, which constantly exerts a driving force on them « while the air pulses generated by the air pulse generator 36 a pawl assembly consisting of x-link disks and pawls control so that old feathers air impulse a latch is released, so that the pre-set joint table can be carried out =,

Since the quantity display 32 and the price display 33 are in the same Catfish are driven and controlled, only the drive and

As can be seen from FIGS. 12 and 13, the quantity display 32 in the usual Welsa contains a series of drums 37, 3d, 39 and 40 lying coaxially to one another, the drum 37 being driven directly by the air pulses generated by the air pulse generator _; 36 come from here. Thus, the drum 37 is steamed once for every tapped quantity, whereby it is provided with markings for fractions of this unit of measure, so that the drum 38 is driven by the drum 37 via a transfer device, conventional type, q © that the drum 38 during each revolution \ of the drum 37 carries out only a Zehntcldrehung · · a * correspond; The inaction then drives the following drum j mein, j

The control system is described below with reference to FIG The Zapf device "s described according to the" invention, the flawless " Ensures pin and prevents any incorrect function.

Duroh the suspension device for the tap 26 is a. .- '.' { Controlled air hold valve 166 which, when the tap 26 is attached, soles a line I67 and holds the air under pressure in it, whereby a hold valve 168 is kept closed, . device 169 separates. The air pressure prevailing in the line I67 also serves to hold the cylinder 145, which is connected via a line 171, in a position in which the device for resetting to the zero position is tensioned. When the tap 26 is removed from its hanger, the air escapes from the line I67 so that the switching valve I68 can open; so that air is given to the cylinder 94, so that the. Friction clutches 78 and 79 which drive the pulleys 71 and 72 of the air pulse generator come into engagement. The air pressure in the cylinder 145 can escape so that the quantity display 32 and the price display 33 can be reset to the zero position.

Air arrives from the switching valve 168 through the line 172 the line I36, the line I72 through a Deokel 173 of the cylinder 145 through to one end of a diametrically opposite one Channel P guided 1st (FIG. 14) j the other end of channel P is connected to line 136. The channel P is generally closed by the piston rod 148, only then not, when the piston 146 to reset the quantity display 32 and the price display 33 is shifted to the zero position and if so then a hanging groove 174 located in the piston rod 148 between the two parts of the channel P establishes a connection.

If there is air pressure at the known control inlet, the changeover switch 175 is actuated so that: Air coming from the switching valve 168 can open a second switching valve 176, whereby air enters the lines W and the turbine rudders 41 of the quantity display 22 and the price display can be driven »Air also reaches the line that feeds the air pulse generator 36; and to the corresponding line, which also acts on the air pulse generator for the price display y ^ . The opening of the switching valve 176 also causes a supply of air to a device (not shown), Ata actuates the electric motor of a drive pump, and an air supply to a device which opens the main valve 22.
