AILUMASC LIMITED, London (Great Britain)

The invention relates to dispensing valves such as those used for serving draft beer or other air or gas containing ones Beverages with high dissolved gas content can be used with a valve plug that opens the valve is lifted by hand from a valve seat in the flow path between the inlet port of the nozzle and the outlet is arranged.

Such dispensing valves for serving high-gas beverages have the disadvantage that the drink is poured out often foams excessively. The invention is intended to avoid this.

The nozzle valve according to the invention of the type mentioned above is-i; characterized in that upstream of the valve seat the flow channel a throttle with widening, adjustable: contains cross-section.

It has been shown that the appropriate setting the throttle prevents excessive foaming: can be.

A particularly suitable embodiment of the invention

O35- (i5SO3 / 7O) -Bgn-r (4)

is designed in such a way that the throttle expands, adjustable cross-section of one in the direction of the Fluid flow widening frustoconical bore and a truncated conical plug that is axially adjustable in the bore is formed.

It is recommended that the flow channel leading to the valve seat have coaxial bores of a nozzle inlet connector and a telescopic adjustable push-on request tion contains and the tapered bore in the push-on extension and the plug in the inlet port is arranged.

This type of construction can be designed in such a way that the plug is attached to an axially pierced bushing is that the liquid over the further end of the frustoconical plug into the bore of this socket can flow, and that this socket is arranged coaxially slidably in the inlet port so that the plug from the Inlet port protrudes and into the frustoconical bore.

In all of these types it is recommended that the inlet connection and the push-on extension be connected to one another are connected by a tJberwurfmu-fctex * which is rotatable but * is mounted on one of these parts so that it can slide axially, the inlet connection and the extension together axially displaceable, but non-rotatable relative to each other are connected.

An exemplary embodiment of a tap according to the invention Valves for beverage aTisschänk is in the drawing dax-ge-Es demonstrate:

Fig. 2 is a partial view in the direction of arrow 2 of Fig. 1 with some parts broken away;

3 is a view of an individual part;

Figure h is a perspective view of an additional part which can be installed in the nozzle; and

Fig. 5 is a section along the line 5-5 of Fig. 4, showing the cooperation of this additional part with the nozzle shows.

The nozzle shown is of the type that is usual and is suitable for serving beverages such as beer, which gas, z. B. carbonic acid, contain that when pouring to isolate yourself quickly from the solution and should seeks to form excessive foam.

The nozzle shown in Fig. 1 includes a housing 1O with a side inlet port 11 and down directed pouring spout. The flow connection between these two is controlled by a valve plug 14, which, when closed, shut off the flow tightly by means of a rubber sealing ring 15, which opens a frustoconical valve seat 13 is seated, which around arranged a leading to the bore of the pouring spout 12 opening is.

The nozzle housing 10 also has an upward

directed nozzle, which is lined with a Fifihrungsbuchse 17, in which a shaft 16 of the valve closure piece 14 slides. In the outer circumferential surface of this guide bush 17, a circular profiled sealing ring 18 is arranged, which rests against the inner circumferential surface of the housing connector; another circular profiled sealing ring 2? is in a N "t disposed of the shank 16 of the Ventilversehluß- i tückes and opposite ddie inner wall of the bore of the sleeve 17 at. These two sealing rings separate the flow path of the fluid from the actuating linkage of the dispensing valve.

This operating linkage consists of a socket

19, which is inserted into the socket 17 and with an inside

flange 20 is provided which has a stop for a valve closing spring 25 forms which at its other end against a shoulder of the shaft 16 of the valve closure piece 14 is present. The socket 19 is held in place by a screwed plank plug 21, which has a recess 22 in its center, which the upper The end of the shaft 16 leads. The spring 25, which is the stem 16 surrounds, presses the valve closure piece 14 against his Seat 13 in the closed position.

The plug 21 also holds an operating lever 23 in place. The Xipp point of this lever is formed by a circular arc-shaped net 24 of the lever, which grips the edge of the housing wall at the bottom of a slot in the housing. The inner end of the lever 23 grips ± in a hole. 26 of the shaft 16 of the valve wear pad i4. When the outer end of the lever 23 is depressed, the locking piece 14 rises against the pressure of the spring 25

his seat 13 "and leaves the drink to be served flow from the inlet connection 11 to the pouring spout 12.

The actuating device described so far is not the subject of this invention.

In the case of beverages with a high gas content, a dispensing valve of the type described above can dispense the beverage allow excessive foaming «The device according to the invention can significantly reduce this disadvantage *

In the arrangement shown (in i * ig * 1-3) the inlet connection 11 with a push-on extension 30 Mistake; the inlet port and this extension are provided with coaxial bores and in the axial direction of the Bores adjustable relative to each other »The extension contains an adjustable throttle; this lets itself through Adjusting the position of the clip-on extension »

So that the position of the inlet connection 11 and the push-on extension 30 can be adjusted relative to one another, a union nut 31 is provided which has an inner flange which is axially fixed between a shoulder 32 of the inlet connection and a snap ring 33 which is attached to the inlet connection is sprinkled. The union nut 31 can therefore be rotated on the inlet connection 31, but not axially displaced. The thread of the union nut 31 engages the extension 30; it has a short axial slot 3 ^ »A * ¹ engaged by a nut screwed into the inlet connection piece set screw 35th Thus, by turning the nut 31, the inlet connection 11 and the extension 30 can be axially displaced relative to one another.

The bore of the attachment extension 30 is stranded with a conical part 36 which is straight in the direction of the flow to the nozzle size τνΐ-π. In this part there is a correspondingly gefoiater plug 37, which is attached in such a way that it retains its position in the inlet port 11 after adjusting the extension 30 and thus the side of the cylindrical outer surface of the plug 37 and the inner surface of the bore 3σ bex ± fidi ± es * s Spaltes -y ^ rä ^ äert «The outside clinging fluid flowed in a thin layer along a generally widening VBg ₃ which - depending on the width of the gap - the flow velocity -rermiiideri.

As the drawing shows, the plug 37 is connected by narrow webs 40 to a bushing 38 which is held in a widening of the bore of the inlet port and pressing on the plug 37 by means of circularly profiled sealing rings 39 arranged in its outer surface fluid pressure causes the plug when adjusting: the extension 30 follows the inlet fitting "through such adjustment, that is, by choosing the gap width, the foams can even heavily gas-containing beverages such. B. master beer.

Ash you can use the plug 37 as © in the shut-off valve, usa to be able to clean the valve closure piece 14 and its operating mechanism.

In Fig « U and Fig. 5 a device is shown with which you can lock the valve closure piece 1 * i in its open position.
