Definitions

  • the invention relates to a compensator tap for drinks, in particular beers, with a hand lever for adjusting the compensator tap from a closed position to an open position and back, an outflow spout for outflow of the beverage in the open position of the compensator tap and a flow chamber for flow of the beverage to the spout wherein the flow chamber has a portion tapering counter to the direction of flow of the beverage, wherein in the flow chamber a portion of a compensator tapering counter to the direction of flow of the beverage is provided, and wherein the compensator is connected to the lever such that the compensator is in the closed position the Kompensatorzapfhahns with sealing surfaces in contact with corresponding sealing surfaces of the flow chamber and thus closes the Kompensatorzapfhahn over a flow of the beverage.
  • a Kompensatorzapfhahn according to the introductory part of claim 1 is known from DE 42 02 633 A1 known.
  • Compensator taps are known in various designs and allow a gradual pressure drop of the beverage in the tap. This is particularly desirable when tapping beer or other carbonated beverages such as soft drinks, because a sudden pressure drop from a high line pressure to the ambient pressure can cause an excessive volume flow from the discharge spout shoots, the carbon dioxide dissolved in the beverage escapes, so that The cone is a shelled drink with a lot of foam is obtained.
  • the compensator of a Kompensatorzapfhahns has a conical end which sits in a likewise conical portion of a flow chamber in the housing of the Kompensatorzapfhahns.
  • the compensator is regularly adjustable in the housing of the compensator tap. If the compensator with its conical end pushed further into the cone of the flow chamber, the remaining free flow area for the drink is lower and the pressure loss through the compensator higher. The pressure of the drink is thus significantly reduced after passing through the compensator and preferably only so high that the drink with the desired quality can be tapped. Since the compensator is relatively long and the corresponding pressure drop is gradually over the length of the compensator, a larger proportion of carbon dioxide remains in the expiring from the spout.
  • the conical compensator may be further withdrawn from the conical portion of the flow chamber, increasing the free flow area and decreasing the pressure loss across the compensator. Nevertheless, since the pressure of the beverage applied to the compensator is lower, the pressure loss through the compensator is not too sudden and sufficient residual pressure remains to allow a sufficient volume flow of the beverage to flow out of the discharge spout.
  • the displacement of the compensator is accomplished via a lever provided on the compensator tap, which is provided in addition to the hand lever of the compensator tap, with which the compensator tap is moved from the closed to the open position and back.
  • a lever provided on the compensator tap which is provided in addition to the hand lever of the compensator tap, with which the compensator tap is moved from the closed to the open position and back.
  • the open position of the Kompensatorzapfhahns the drink flows out of the spout.
  • no beverage flows out of the spout.
  • a closing piston is provided in the flow chamber, which closes in the closed position downstream of the compensator flow opening in the flow chamber.
  • compensator taps are that they can be used very flexibly for different pre-pressures and for different drinks, especially for different beers.
  • compensator taps can be used to pour high-quality drinks.
  • the object of the present invention is to design and further develop the above-mentioned Kompensatorzapfhahn described in such a way that the output can be increased without increasing the production cost or to reduce the quality with which drinks can be tapped.
  • the compensator comprises at least one Kompensatorkanal for flowing through the compensator with the beverage in the direction of the tapered portion opposite annular outlet opening for the outflow of the beverage from the Kompensatorkanal.
  • the closing of the Kompensatorzapfhahns by the compensator in the closed position of the Kompensatorzapfhahns and the adjustment of the compensator by the hand lever for tapping the drink eliminating the need for a closing piston.
  • the invention has recognized that thereby the flow through the flow chamber after passing through the compensator can be improved so that sudden cross-sectional changes and / or flow deflections are largely avoided. As a result, the carbon dioxide tends to escape less and thus leads to the pin less foaming.
  • a closing piston By dispensing with a closing piston, a higher pressure can ultimately be tolerated downstream of the compensator in the direction of flow of the beverage, without resulting in excessive outgassing of carbon dioxide in the compensating tap.
  • the beverage is at a higher pressure after passing through the compensator and can be tapped faster. The number of drinks tapped per unit time can therefore be increased.
  • a tapered compensator can be understood as meaning a conical compensator or a compensator with a conical section.
  • the compensator can form a cone and the Flow chamber form a flow channel for receiving the compensator, which is also designed as a cone.
  • a corresponding tapering of the compensator or of the flow chamber can also be understood to mean that, in the mathematical sense, does not resemble any conical shape, but differs therefrom. However, this deviation is preferably not too great, since the function described above must be achieved further from the interaction of compensator and flow chamber.
  • the hand lever to which the compensator is connected means the hand lever operated by the operator to start, stop or stop the pin. Not meant, however, is an adjusting lever, which merely serves to adjust the compensator tap. Since the compensator is connected to the hand lever, it is necessary, if necessary, no further adjusting lever more, as provided in the prior art, for example, for adjusting the compensator.
  • the term hand lever can also include actuators that have no lever structure in the classical sense and / or not operated directly by hand. For ease of understanding, however, the term hand lever is still used because the design of the hand lever will be preferred as a hand lever in the classical sense, with the exception of specific exceptions.
  • the corresponding sealing surfaces of the compensator and the flow chamber are each provided in the tapered portion. In this way it is structurally particularly simple to close the flow chamber of the compensator tap and to prevent leakage of beverage from the spout, by merely adjusting the hand lever in the closed position.
  • the corresponding sealing surfaces of the compensator and the flow chamber may be circular or oval. However, the sealing surfaces can optionally be made simpler and more accurate if they just run are. Then several sealing surfaces are provided circumferentially for sealing the flow chamber. It can be provided in each case six to eight or even more sealing surfaces. The sealing surfaces are then easy and accurate to produce, with approximately a conical shape of the flow chamber and compensator can be maintained. However, it is also possible for a plurality of sealing surfaces to be provided on the compensator and / or on the flow chamber, which has a curvature or curvature, even if this is rather less preferred in terms of production technology.
  • the sealing surfaces of the compensator and / or the flow chamber can be rolled, whereby a very high tightness of the Kompensatorzapfhahns can be ensured in the closed position. A run-on or drop of drink is thus prevented.
  • a flow channel which is at least partially limited by flat surfaces of the flow chamber and / or the compensator.
  • Surrounding the flow channel are preferably, in particular in each case, at least six, eight or more, flat surfaces provided which can merge into one another.
  • the flat surfaces achieve a defined and even flow. For example, this may result in less foam.
  • the flow channel is formed circumferentially to the compensator.
  • the compensator carries a plastic coating. Chlorinated plastics, in particular polytetrafluoroethylene (PTFE), have proved to be particularly suitable in this context. Since appropriate deposits should also be avoided at the flow chamber, alternatively or additionally, the flow chamber can be internally coated with a plastic, preferably of the aforementioned type. If the Sealing surfaces of the compensator and / or the flow chamber are formed by a plastic, can also be increased by a certain elasticity of the plastic, the reliability of the seal.
  • PTFE polytetrafluoroethylene
  • the compensator can basically be made completely from a plastic. However, it is advisable if the compensator is formed, for reasons of dimensional stability, at least in its core of a metal. Aluminum is particularly preferred because the compensator assumes the temperature of the beverage very quickly and is less prone to heat the beverage when tapped. Likewise, it is preferred if the housing of the compensator tap is at least partially made of metal, in particular aluminum.
  • an adjustable stop can be provided.
  • the opening degree of the Kompensatorzapfhahns can be varied in the open position.
  • the stop serves to limit the adjustment of the compensator from the closed position of the Kompensatorzapfhahns in the open position of Kompensatorzapfhahns. This leads to a constructive simplification insofar as that the compensator is adjusted anyway via the hand lever between the open position and the closed position. So it can be reduced, the number of moving parts.
  • the stop is formed by a screw held in a thread of the housing of the compensator tap. In this case, too, it is generally preferred if the stop serves as a stop for the compensator in the closed position of the compensator tap. A further simplification can be achieved if the screw forming the stop is screwed from the front of the Kompensatorzapfhahns into a thread in the housing of Kompensatorzapfhahns.
  • a ventilation duct may be provided for ventilating the flow chamber.
  • the ventilation channel is provided so that in the closed position of the Kompensatorzapfhahns the compensator or a component connected to the compensator releases the ventilation duct. In the open position of the compensator tap, however, the compensator or a component connected to the compensator closes the ventilation duct.
  • a sealing means may be provided which cooperates with the compensator or with a component connected to the compensator so that the ventilation duct at the earliest shortly is opened in the closed position before the Kompensatorzapfahn completely closed.
  • the sealant is designed as a ring seal.
  • the sealing means is provided in the open position of the Kompensatorzapfhahns between the stop and either the compensator or a cooperating with the stop and connected to the compensator component.
  • the compensator is adjusted anyway between the open and the closed position of the Kompensatorzapfhahns.
  • the ventilation duct can alternatively or additionally be guided by the screw forming the stop.
  • the flow chamber may be formed at least in two parts. Then the flow chamber can be opened by separating the corresponding parts and cleaned from the inside. If the at least two parts of the flow chamber are connected to one another via a union nut, it can additionally be prevented that a screw connection of the parts of the flow chamber is contaminated by escaping beverage residues. Corresponding threads are difficult to clean. If necessary, the compensator may be formed in two parts, such as to make the compensator in the individual parts better, even if this requires a subsequent connection of the items.
  • the compensator channel can be designed as a channel open to the flow chamber, for example in the form of a channel.
  • the compensator channel runs at least partially closed in the compensator itself.
  • the compensator channel is then accessible only via at least one inlet opening and / or one outlet opening in the compensator, wherein the beverage flows through the at least one inlet opening into the compensator channel and / or through which at least one outlet opening flows out of the compensator channel.
  • a high flow rate and a particularly uniform flow of the beverage through the compensator channel is achieved if the at least one compensator channel at least partially has an annular cross section for flowing through the beverage.
  • the compensator has several, in particular at least two, inlet openings. These inlet openings are preferably arranged to further homogenization of the flow of the beverage, in particular evenly distributed over the circumference of the compensator. In case of two inlet openings are therefore preferably provided on opposite sides of the compensator.
  • the at least one inlet opening at the end of the tapered portion at the beginning of the non-tapered portion or in particular at the transition region between the tapered portion and is provided non-tapered section.
  • the at least one outlet opening is annular. This is particularly appropriate if the compensator channel also has an annular cross-section at least partially, in particular in the region of the at least one outlet opening.
  • the use of at least one rod element which can form the front end of the compensator, is necessary.
  • the rod element can be used to interact with the stop, the ventilation channel and / or the sealant.
  • the rod element can cooperate with a ventilation channel such that the ventilation channel is closed in the closed position of the compensator tap and opened in the open position of the compensator tap.
  • a sealing means such as in the form of a ring seal may be provided which ensure the seal, for example, ensures the ventilation duct.
  • the rod element can engage in the open position of the Kompensatorzapfhahns in an opening of the sealant.
  • the rod element can be at least partially enclosed by at least one Kompensatorkanal.
  • it can contribute if the Rod member at least partially limited at least one Kompensatorkanal, in particular to the inside.
  • the rod element can be arranged centrally and concentrically with at least one compensator channel.
  • the compensator is formed in two parts, this allows a simple production of Kompensatorkanals.
  • the rod element can be subsequently connected to the rest of the compensator. This is done very easily and reliably by screwing.
  • the compensator channel preferably does not extend over the entire tapered rear portion of the compensator, it may be desirable to connect the rod member to the tapered portion of the compensator. As a result, it can also be achieved that the compensator channel extends at least substantially over the entire non-tapering section, which is not formed solely by the rod element.
  • the Kompensatorkanal can then also be formed by a blind hole, in which subsequently the rod element is introduced.
  • a Kompensatorzapfhahn 1 for tapping beer or other, preferably carbonated drinks, shown in a side view.
  • the illustrated and so far preferred Kompensatorzapfhahn 1 has at its rear end a connector 2 for connection to a not shown beverage line in the form of a threaded connection. From the beverage line, the beverage flows into a flow chamber 3 in the housing 4 of the compensator tap 1.
  • a hand lever 5 is pivotally mounted, which can be pivoted from a rear closed position to a front open position.
  • the beverage flows through the flow chamber 3 and the downwardly facing and slightly forward discharge spout 6 from the Compensator tap 1 out.

  • the compensator 12 is connected via an eccentric 14 with the hand lever 5, so that the compensator 12 is displaced by the pivoting of the hand lever 5 along the flow chamber 3.
  • the eccentric 14 is rotatably held in the housing 4 of the Kompensatorzapfhahns 1 and engages with an eccentrically provided pin 15 in a corresponding receptacle in the compensator 12 a.
  • the compensator 12 therefore moves forward when the hand lever 5 is pivoted forward.
  • the compensator 12 is also displaced to the rear, when the hand lever 5 is pivoted to the rear, until the closed position of the Kompensatorzapfhahns 1 is reached.
  • the compensator 12 is screwed with its rear end in the flow direction with a pin-shaped component 18.
  • the pin-shaped component 18 points in the direction of the stop 16 and lies in the open position of the Kompensatorzapfhahns 1 to the stop 16, as shown in the Fig. 4 is shown. If necessary, but could also be dispensed with the pin-shaped member 18, so that the compensator 12 itself comes into contact with the stop 16.
  • a sealing means 19 and a ventilation channel 20 are shown.
  • the ventilation duct 20 is guided in the illustrated and so far preferred Kompensatorzapfhahn 1 by the seated in the housing 4 screw 10, in the present case in particular approximately centrally.
  • the pointing in the direction of the flow chamber 3 end of the screw 10 is frictionally seated in the sealing means 19, which in turn is positively received in a groove 23 in the housing 4 of the Kompensatorzapfhahns 1.
  • the sealant 19 is formed in the illustrated and so far preferred Kompensatorzapfhahn 1 as in the form of a ring seal. In principle, it may be sufficient if only the pin-shaped component 18 connected to the compensator 12 or the compensator 12 itself cooperates with the sealing means 19 for closing the ventilation channel 20.
