As soon as this temperature is reached, heat regulating devices interrupt the function of the cooling unit and afterwards switch themselves on again to the temperature "within a certain cn differential", taking into account the heat dissipation to the environment during refilling with drink, to be kept constant.

In some cases such agents squirt the drink against the walls and the lid of the container, which is a rioinent of attraction for those interested.

As to the class of so-called Ausschenkautoinaten properly may still those Ausschenkgerätc be considered in which the fully automatic Ausschcnkvorgang not nwurf by the Müiszoi but is triggered by depressing a Druckknopfew or ¹ key.

Such devices are intended for pouring points where a particularly 'fast and smooth administration' is desirable is.

Coming back to the description of how the hand-operated pouring device is offered by the Hünz pouring device (as well as: the DruclJ iiopf-Au ^ p.sclienkgcät) in general a difficult basic question, i.e. the non-availability of what is served. Amount even with a changing drink stand in the Bell a It er.

To solve this question, some manufacturers use a timer that does the job of t-ie Of f nr ng .sz ext c - des üclienkhalmes to control and constant to Julten, And they install a pump under pressure (the free beverage surface) in front of the tavern, which means a pressure control able to achieve global tracking; thereby use they are tapping under pressure during an equal Length of time, instead of free drainage of the drink.

Even if in theory the delivery head of the pump (which determines the discharge ^{pressure Le r} : ciiiunt) can be viewed independently of the current level of the beverage in the container, this is not the case in practice.

The limited size of the machine, the location in which the

Pump arranged opposite the free beverage surface the speed limits (and thus the pressure), which the jet to be metered by the The necessity to prevent splashing or overflow in the cup entails that the The delivery head on the pressure side is always influenced by the different beverage stands, so the disadvantage is not entirely eliminated by this.

Another solution to the problem is being sought by other manufacturers by providing the amount of drink to be administered in the dosJeren in advance, so that the use of a timer is not necessary.

In ßo ^ 'hen filling - inside the container - one with the tap connected dosing device arranged ^ de · en Capacity of the consistently administered accordingly.

The dosing device is driven by a pump (usually the same that also to Stirring the drink serves) always full held.

At the time when the pouring begins _s is the function of the Pumpο interrupted (the same device ^ that open the the Dohenkhah' it-causes also discontinues the pump feeding circuit), with the metering device emptied and the right, always the set measure, the same amount of beverages flows into the cup »

The disadvantage of this solution, which can solve the problem in principle, is the dosing device with a fixed capacity.

Every time the amount of drink to be administered is changed be foil, the dosing device must be with another

can be exchanged, which is undoubtedly a major limitation both in terms of production and use represents that a set of dosing devices with different capacities are provided or purchased

The aim of the invention is to completely solve the problem by ensuring the absolute constancy of the beverage administered.

If-

Amount ensured despite a change in the beverage level in the container and there is also the possibility of increasing or decreasing this amount depending on the operating requirements.

For this purpose, a dispensing device of the type is proposed which contains the following components: a container for the drink, a pouring cup attached to the bottom of the container

tap and a timer that shows the opening time of this tap controls, and characterized isv that a Rr * hr on the mentioned Hahn is connected that is perpendicular in the interior of the container extended and its mouth at its free end reaches a higher level than the maximum permissible beverage residue- ^ nd in the container, and that this pipe with the pressure line is connected to a pump, the suction line of which is connected to said container, the delivery rate of this Pump is greater than the flow rate of the swivel valve.

These and other terms, purposes, and advantages of the invention will become more apparent from the following description of an example referring to the attached, single sheet of drawings, where a preferred embodiment of an invention The pouring device appears to be shown in the table.

A cooling device 8 is provided on the bottom of the container 3, which x.

The swivel tap 22 is located above a display plate Si which protrudes from the dome substructure 2 and on which a cup 6 ccstel.lt vird,

The connecting piece 21 also has a radial bore 23, the function of which will be explained later.

The warmeregelude device 11, the feeler member rait the Evaporator 9 is in operation and is therefore able to Measuring the beverage temperature interrupts the function of the cooling unit 10 as soon as this temperature reaches the value selected in advance, and the cooling unit switches each time again to the temperature (within a certain differential) versus the heat dissipation to the environment and to keep constant after refilling with drink.

The impeller 12 of the pump, which is set under the pressure head (the free beverage surface) by the permanent magnet 13 in. UmJ on, sucks in drink through the suction opening 15a and conveys it under pressure to the pressure line 15. A rope of the drink runs from the line 15 directly back into the container 3, in a conventional manner via the free mouth 17 and the Running r-adially> -ien branches 16 and 18 of the same pipe.

The beverage jet flowing out of the end V] of the line 15 hits the inner surface of the lid 4 * where it breaks and distributes itself in such a way that it. the liquid falls like rain along the walls of the container, creating an optical effect that is suitable for attracting the attention of interested parties.

The stream of drinks flowing out of junction 16 calls out a rotating stream around the cooling unit 8, which improves the heat exchange between the cooling unit and the beverage.

The Ie beverage jet coming out of the junction 18 has the purpose of keeping the response temperature of the thermostat 11 constant. For further explanations in this regard, reference is made to the utility model No. 128 »120, which is in the name of the same Annielderin.
