Dispensing arrangement for beer kegs and the like.

The present invention "relates generally to the art the liquid siphon unc in particular an improved one Tap adapter and a tap assembly for beer kegs and the like. for drawing liquids such as beer therefrom using a gas such as air or carbon dioxide as a print source.

The system of dispensing beer from kegs that has prevailed for many years required a wooden stopper, the one Opening in one end of the barrel locked. This stopper had to be removed from the bartender, who then made an elongated one Inserted a peg assembly into the hole, which was combined with a lifting assembly. Funds were provided to pressurized air or carbon dioxide gas through the power take-off assembly to be pressed into the keg, whereby the beer was pushed out of the keg through the siphon to a tap, who controlled the flow of beer from the keg.

After the available beer was withdrawn from the keg, the bartender took the peg assembly and lift assembly from the void. Pass out and the same procedure on one

3Ö9816 / Ö367

full barrel. Because you have the same PTO assembly and lifting equipment was used over and over again, it had to be cleaned frequently to remove yeast deposits and bacteria to remove so that the beer in the newly pierced keg was not contaminated.

Another problem with the aforementioned dispensing system was that after removing the plug, the opening of the empty barrel was not closed, whereby foreign substances and -body could get into the empty barrel. It was time to clean these barrels in the brewery before refilling them then time-consuming and costly.

Various beer dispensing arrangements are proposed each having an adapter mounted in the barrel and a spring-loaded valve that is closed remained in order to prevent the beer from escaping until the tapping device was attached to the adapter and actuated with a probe opening the valve and the beer flowing out under the pressure of compressed air or carbon dioxide let. Although these various forms of barrel adapters and dispensing arrangements according to the prior art already exist Brought improvements, they did not work completely satisfactorily, mainly because of the problems which apply when washing all parts and channels in the adapter, including the various Coil springs that close the valves or their parts held in mutual investment.

Another problem was that the power of the used to wash the barrels with the adapter inserted Water was usually not big enough to hold the main feather,

309816/0367

that kept the beer valve closed. For this reason, a finger fitting was required to counter the pretensioning of the various valves Fodem opened.

Another problem was posed by the coil spring that was used was to keep the main valve closed in front of the spigot. This spring "sat" in the compressed one Position, i.e. with the valve open, and could therefore open the main valve during transport after repeated use of the keg no longer close properly, which resulted in a loss of beer and pressure.

Another problem with the prior art arrangements The technology lies in the fact that it is for female bar staff it is often difficult to correctly place the tap assembly on the barrel adapter and then the probe for tapping the Barrel to operate.

Given the mentioned limitations and shortcomings of the Dispensing arrangements according to the prior art and difficulties encountered despite the improvements achieved It is the main object of the present invention to provide an improved keg adapter for beer kegs and the like., which contains relatively few parts and thus simplifies its cleaning. In particular, the barrel adapter according to the present invention relatively few parts, and these are simple in design, as well as the Adapter has relatively smooth beer and gas flow paths. IL.or can use the adapter with a minimum aη time and effort to clean while he is at the barrel to g (ibra cht i ί i t.

The advantages of the present invention can be achieved with a dispensing device from a barrel adapter and another tap assembly, the barrel adapter having a housing made of magnetic material that can be inserted into an opening in the barrel and has gas and liquid channels, which include valves that are resiliently biased closed by actuators that Permanent magnets included. The magnetic actuators keep the valves closed during the filling of the keg and during shipping, but can be opened by a water flow entering the channels easily into the open position bring, such as when the barrel is in front of a renewed Filling is washed. The dispensing assembly is connected to a source of pressurized gas and a beer tap has gas and gas that are in flow connection with these Liquid channels that are provided with valves to control the gas or liquid flows. the Dispensing assembly can be brought into engagement with the barrel adapter and has a dispensing rod which, when operated manually the dispensing assembly seals off tightly with respect to the adapter and opens the valves in the dispensing assembly, after which gas flow into the keg and the beer can be tapped from the tap.

Oblgeich the dispensing device according to the present Invention can be used to lift a number of different liquids from their containers is they are particularly suitable for tapping beer and being described here for this application. You can also see! that different types of pressurized gas, sources and taps can be used and that barrel and gas bottle under the counter £ a (tavern or bar or in the Cellar or storage room of a restaurant can be accommodated.

In FIG. 1, the reference number 12 generally designates a dispensing device according to the teaching of the present invention} as it is used in a conventional beer keg 13. This has a filler opening 14, which is through a Plug 15 is closed, and is via a hose 18 with a compressed air or fluorine dioxide bottle 16 and connected to a tap 20 via a hose 21.

The dispensing device 12 (FIG. 2) has a dispensing arrangement which can be inserted into the barrel adapter 24, the latter being located in an opening 26 in the wall 28 of the barrel is located.

The barrel opening 26 includes an inwardly directed lower flange portion 3o with a support surface 32 and is surrounded by an upwardly directed flange part 34 with an internal thread 36.

The barrel adapter 24 (Figure 2) has a cylindrical housing 38 made of magnetic material such as stainless steel with an outwardly directed upper flange part 4o, which has an O-Hing 42 on the mentioned support surface 32 rests.

The adapter is secured by a conventional retaining ring45 held in place; this rests on the upper surface of the paddling part 4o and has an inner recess 45 with opposing slots 4-7.

There is one in the upper end of the adapter housing Annular groove with a bottom surface 44 and an outer side wall 46 with a shoulder 48. Of the bottom wall 44 of the Groove extended two diametrically opposed gas, J channels 5o through the housing, each with a lower » Have inner wall 51 and a valve seat 52 in the upper part. A gas valve is located in each of the gas ducts in the preferred embodiment used, a separate valve member 56 consisting of a flavor and a odorless, resilient material such as neoprene and can apply to the valve seat 52, as well a valve actuator 58 made of a permanent magnet 6o, which sits in a smooth housing 62 which slidably rests against the lower wall 51 of the gas duct. Excellent results have been achieved with housings made of magnesium and plastic; those are made of stainless steel, also acceptable if the metal is so thin that it does not add materially to the weight of the actuator. The valve actuator should therefore be as light as sfj to be possible. The upper end of the housing can be closed with a Teflon insert that holds the magnet in place holds in position without any obstruction in the gas duct occurs.

As can be seen, the center of each magnet 6o from the center of the "" ground "of the metal adapter housing is j> 8

309816/0367

Moved down. As a result, each magnet tends to move within the gas channel 50 to the center of the housing, where there is less magnetic resistance and the magnetic lines of force have the shortest path through the housing 38; As already mentioned, this is also made of magnetic material - such as stainless steel. As a result, each valve member 56 is biased towards the closed position by the associated actuating member 58 and rests on the valve seat 52.

In the upper part of the adapter housing are diametrically opposed Gas passages 64 are provided which are in communication stand with the gas ducts and the valves. 56 adjacent are. This allows the gas to the valve members 56, if they are in the open position, flow past and into the interior of the barrel 14, as detailed below is described.

A extends from the center of the adapter housing 58 tubular bayonet part 66 upwards, which has an outer wall 68 with an outer annular groove which has a O-input 7o picks up.

The center of the tubular bayonet represents a beer channel 72 with a valve seat 74 (FIG. 2) and a lower one Inner wall 76, with the channel at its lower end is in fluid communication with a lifting tube 78 of conventional construction. This lift pipe is through one Removable threaded fitting at the lower end of the adapter housing j> 8 attached. As shown in Fig. 1, the Hc tubing 78 in the conventional manner up to the baht of the Bottom of barrel 14.

In the beer channel 72 is; Slidably mounted a beer valve assembly comprising a valve member So _1, which is preferably made of a viscous and odorless material such as neoprene, and a valve actuating member 82, these are shown here as separate elements. However, it is to be understood that the valve arrangement can also be made in one piece. The valve member 8o can bear against the valve seat? whose radial AhmeSrsungen are chosen so that the outer end faces slide against the wall 76. This prevents the valve member 8o from tilting and jamming in the channel 7? when moving relative to the valve seat 74- avoided.

Although the mentioned valve members 56 i & the gas channels are shown as provided with cylindrical bodies, it is advantageous, even with these valve members - similar as with the Ventifelied 8o in the beer channel - small radial flanges should be provided.

The valve actuator 82 has a permanent magnet; 88 on the sieve, in a housing 90. This has Also at the upper and lower ends there are short radial flanges 92 (FIG. 9), which slide on the wall 76 of the beer channel 72 issue. A small 9-4 Teflon pot can be placed in the top Housing 9o are used, mainly to hold the magnet 88 in position in the housing »As above Mentioned, it is advantageous to borrow the «housing from a # n To manufacture material.

As already mentioned above, the length and position of the magnet 88 are ^{offset from the center of the "mass 11" of} the housing, so that the valve actuator 82 presses the valve element 8o into the closed position, ie onto the valve seat 74.

As can be seen, form between the flanges 86 of the valve member 8o or the flanges 92 of the valve « Actuating member 82 and the inner wall of the beer channel free trees to be in the open position Valve member 8o to allow the free flow of beer, as described in detail below.

Near the lower end of the housing 38 (Figure 2) is a Sleeve 96 pressed into the beer channel 76 around a shoulder 98, which limits the downward movement of the actuator 92.

Vie stated above and known in the art is made before the keg adapter 24 / keg 14 when pouring the beer used, the retaining ring 43 him in ssiner position holds on. It is conventional practice to use a barrel of this type to fill through the opening 14 in the side wall of the barrel, the opening is then closed by a wooden plug 15.

As explained above, the actuation jsgliadej »5® W? 4 82 the assigned valve members in the §§hüej§tstellung | This prevents the beer from being poured in flows through the gas channels 5o and the beer channel 76.

Furthermore, the beer in the keg is subject to a residual or Filling pressure, which is usually around 9 to 34 p.Sii. (0.63 up to 2.39 kg / cm); this pressure obviously helps to keep the valves in the closed position.

However, if the barrel 14 is empty and the filler plug 15 was removed to wash out the barrel with the adapter 24 inserted, a water hose fitting (not shown) can be attached to the flange 34- (Fig. 2). The water pressure then releases the valve members 56 and 8o from the valve seats and allows the water to enter the keg through the beer channel 76 and the gas channels 50 and the passages 64 to reach. Because of the use of permanent magnets in housings designed to be aerodynamic, neither screw springs If there are still similar turns, the barrel adapter is cleaned quickly and effectively. As already mentioned, coil springs can "settle" with prolonged use as a result of material fatigue break and must therefore be replaced frequently. ImJ In contrast, the permanent magnets act as valve actuators used, the same service life as the drum adapter housing itself.

The lower end of the tap rod 12o is a fire chamber 156 drilled out with an inner wall surface 158, which slidably and sealingly rests against the outer wall 68 of the tubular bayonet element 66 of the fitting adapter. The lower one The end of the pivot rod 12o also has an edge 16o, which can be placed on the surface 44 of the adapter housing.

As shown in FIG. 2, the spring chamber 156 takes one Helical spring 162 with a free lower end, which on the Attack valve member 8o and remove it from its seat. .

The lower part of the lower peg housing 1o8 has a chamber which the lower end of the peg 12o and has an upper shoulder 164 which cooperates with the o-fiing 154 to form a valve. Farther there is an inner wall which is spaced from the outer surface of the pivot rod 12o in order to between to form a channel 166 for these parts.

An annular outer groove with one therein O-ring 168 is on the lower. End of the lower housing provided; the O-ring 168 can be placed against the shoulder 48 in a sealing manner.

Above the mentioned chamber and shoulder 164 is a channel which slidably receives the pivot rod 12o and is drilled out at the lower end to create a chamber 1? o to form that surrounds the pivot rod. Furthermore this is Channel also drilled open at the upper end to the ring wall 14o

of the actuating member and a shoulder 172 to form, which rests against the lower edge of the ring wall.

The gas channels are now to be described in detail with reference to FIG the pig. 3 to be described. The upper housing 1o6 is provided with a gas hose connection 174 to which the Hose 18 is attached. Furthermore, this is in flow connection with an L-shaped channel 176 * thereof lower end slidably and sealingly receives the upper end of a nipple 178 with a channel 18o.

The lower end of the nipple 178 is slidable and sealingly in channel 182 of the lower housing; this Channel itself is in flow connection with a pressure chamber 184 (FIG. 2) via passages 186 and 188 and 3)

As shown in Fig. 2, the pressure chamber 184 is through a narrowed channel 192, at one end of which a. Valve seat 194 is located, with one side of a diaphragm chamber in flow connection.

A conventionally designed membrane 196 extends through the aforementioned membrane chamber; it carries a valve body 198, the O-ring 2oo is arranged in a groove that is at its free end. The O-ring can be placed on the valve seat 194. The valve body 198 is conventional Way - for example. By a helical spring 212 - pretensioned in the open position.

Furthermore, a lower chamber 2o4 is connected to one side of the diaphragm chamber 19o, which is a resilient

"Duck bill" valve member 2ο6 receives. The movable one End of this "duck bill" valve extends through a passage 208 which is in preliminary communication with the chamber 170 which surrounds the pivot rod.

As will be explained in detail below, is between the upper and lower housings I06 and I08, respectively Limited vertical movement is possible in order to ensure a tight seal between the dispensing assembly 22 and the adapter 24 to care. The construction provided for this seal has two opposing bands 21o (FIG. 3), from which Fig. 3 shows only one.

The upper end of every tape 21o engages in a recess 212 in the upper housing and is, for example, by a screw 214 fastened in it. The middle section of each volume contains a slot 216 that receives the shaft of a screw 218 attached to the lower housing I08, wherein the S is slightly wider than the diameter of the screw shank is to allow the mutual movement mentioned above. There is a at the bottom of each band Hst part 22Ü, which extends ± hh through the slot 47 and engages in a groove 45 in retaining ring 43. Through this the tap assembly is attached to the barrel adapter.

In use, the adapters 24 are inserted into conventionally constructed barrels 14 and are through the conventional retaining rings 43 held in place.

The kegs are filled with beer through the openings 14 in the side wall, whereupon the opening is conventional Way closed with a stopper 15.

As mentioned above, the valve members 56 block the. Gas channels 5o and the valve member 8o the beer channel 72 as a result of the associated valve actuating members equipped with permanent magnets. As. also mentioned above, prevails in the barrel of a Fulldruek of about 9-34 psi (0.63 to 2.39 kg / cm ^2), äes helps to hold the mentioned valves closed.

To tap a full barrel 14, this is placed upright, as shown in FIG. 1, the barrel adapter 24 faces up. The tap assembly 222 is pushed down onto the barrel adapter 24 so that the Hook parts 22o of the straps 21ο into the slots 47 of the Retaining ring 43 and engage in the Hingnut 45. Farther the spring chamber 156 takes the bayonet part 66 'of the adapter, the OrRing 2o sealingly against the Inner wall 158 abuts; See * Fig. 2.

Then the tap assembly 22 is a total of about 90 ° rotated to move the hook portions 22o into the hat and out of the slots 47.

If the tapping arrangement has been used before or When the gas bottles 16 were initially opened, the compressed air or the carbon dioxide gas flows through the hose connection 174 and channels 176, I80, 182, 186, 188 into the Pressure chamber 134.

If the gas pressure is too high, the diaphragm 196 moves outward, causing the O-Bing 2oo to move onto the Valve seat 194 is in place and prevents gas flow in the area of the peg.

10-9818 / 0367

If the gas pressure is within the permissible value range, the gas flows through the diaphragm chamber 19o, the lower chamber 2o4, past the duckbill valve 2o6 and through the passage 2o8 into the annular chamber 17o, which surrounds the pivot rod 12o.

If the tapping arrangement has already been used for tapping beer was used, the beer channel 126 includes a beer column above the top of the dispensing rod 12o.

To initiate the tapping function, the handle 128 (Figures 3 and 6) about 180 ° clockwise from the clasp turned to the open position. This causes the armatures 122 and 123 of the actuator assembly to move relative to the upper housing 1o6 down and the Vand 13o descends from the head of the screw 142 until it is on top of the Tapping rod 12o rests and pushes it down until the lower edge 16o of the spring canopy wall to the horizontal Vand 44 of the adapter strikes.

This downward movement of the pivot rod 12o opens the gas channels and the beer channel as shown in Fig. 5 and on is explained below.

So when the pivot rod 12o is down and the Q-ring As the shoulder 164 passes, gas flows from the chamber 170 down through the chamber 166 and into the gas passages 5o above the valve members 56. The gas pressure lifts the valve members 56 from the valve seats against the force of the actuators and allows the gas to flow through the passages 64 in the barrel when the gas pressure in the container

309816/0367

higher than the gas pressure "· 'in the passport. This increases the pressure on the surface of the liquid, forcing it up into the tube 78.

With regard to the beer flow, the downward movement of the tubular fittings 122, 125 the O-ring 144 · on the Walk past shoulder 136, removing the beer from the canal mn the annular groove 148, through the passages 15o in the beer · Channel 146 in the tapping rod and in the spring of chamber 156 - flows over the valve member 8o.

With further downward movement of the tubular fittings 122, 123 and when the wall touches 1Jo with the upper one At the end of the pivot rod 12o, this is moved downwards, like already bescbj .- 'i'.ben, and the free end of the helical spring 162 moves the valve member 8o away from the valve seat 74, causing the beer in the siphon pipe up through the beer channel 72, past the valve member 8o and into the fire chamber 156 can flow wherever it is with the beer from the beer hose 21 mixes.

Obglebh this mixing of the old with the fresh beer in the counting arrangement may seem undesirable, it represents actually represents an advantage, since the beer column between the tap assembly 22 and the tap 2o prevents the beer becomes "wild", as would be the case if the beer line 21 were empty and the beer from the keg into the open one Hahn shoots into it. Obviously every time when the Ilahetn 2o is opened, beer from the keg through the various channels and the beer hose to the tap, since the gas pressure prevails at the tapping point of the keg.

Every time the gas pressure in the passport is below the gas pressure falls in the gas cylinder 16 and in the gas channels 5o the gas valves 54 pushed open to provide additional for the inflow Gas in the barrel.

As mentioned above, relative movement is possible between the upper and lower housings 196 and 108, respectively; this provides a good seal between the spigot assembly 22 and the mating adapter 24.

In describing the dispensing function, it was noted that the tubular fittings 122, 123 and the dispensing rod 12o can be moved down to the gas cylinder with the gas channels 5o and the tap 2o with the inside of the barrel connect to.

From Fig. 2 and 3 it can be seen that in the downward movement of the fittings 122, 123direct the operation of the handle 128 the lower edge of the hanging wall 14o of the upper housing rests against the shoulder 1.72 of the lower housing and thereby pushes the lower case downward away from the upper case. However, since the upper housing 1o6 by means of the straps 21o (Fig. 3) is attached to the retaining ring 43, arise through this Downward movement of the lower housing results in two results: First, the O-ring 168 (Pig.5) becomes sealing against the shoulder 48 pressed against the adapter 24, and secondly, the hook parts are o 22o (Figure 3) in firm engagement with the grooves 45 in the Retaining ring 43 brought.

To separate the tap assembly 22 from the adapter 24, wherein enter the various channels. Beer column is located, you turn the handle 128 counterclockwise to the

! Relieve the pressure between the lower edge of the single wall 14α and the shoulder 172 and cause the tubular fittings 122 »123 to move upwards relative to the upper and lower housings 1o6" and 1o8 and relative to the pivot rod 12o. When walking past the shoulder 136 At the Q-Bing 144, no beer can flow from the channel 146 into the tap rod and into the beer channel 126. If the O-ring 154 continues to run past the shoulder 152, no gas can flow from the hanging chamber 10 into the chamber 166 either stream.

If there is no more gas flow into the barrel and the gas pressure has equalized at the ends of the arrow members 56 and the actuating members 58, the actuating members 58 push the valve members £ 6 into the closed position and thus block the gas channels to the barrel,

Another upward movement of the PTO 12o - either under the pressure of the Bi he column in the channel 46 or by the application of the Vand IJo to the head of the screw 142 - moved the coil spring 162 mcfc open and leaves the force of the actuator 82, the beer valve member 8o in the Press closed position *

If the beer and gas valve © in the keg adapter are in the closed position and the gas and beer channels are still blocked in the dispensing arrangement, one can obviously remove the dispensing arrangement 22 from the fassadeßber 24, change it by turning it, the hook parts 22o of the straps 21 bit ο with the shit 4? of the retaining ring 45 are aligned.
