Compensator tap for wheat beer

The invention relates to a compensator tap for wheat beer with a device for releasing,

Conventional taps with a cock plug and sealing seat are usually used to tap wheat beer. in addition, a flow compensator is connected to the beer flow to reduce the pressure of the same.

A disadvantage of devices designed in this way for tapping wheat beer has proven to be that that the built-in components, such as cock plugs or '' Valve piston, sealing seat, spring, but possibly also the connection transitions between the compensator and tap, here are disturbing in the beer flow and must therefore be flowed around by it, which leads to undesirable effects fouling and thus leads to premature foam formation.

In a device designed in this way for tapping wheat beer, there must also be a disadvantage. will see that the choice of one to be added Compensator. " with regard to «a pressure reduction capacity wrongly and therefore unspecifically can, so that the required pressure reduction does not meet the given requirement.

The invention is based on the object · to avoid the disadvantages listed and a dispensing device for

To create wheat beer in which the beer flow »has no disruptive installations to flow around and between Tap and "accordingly · !!! compensator specific pressure reduction capacity structural affiliation exists.

The task of the invention is surprisingly simpler This is achieved by a tubular tap housing that extends in the direction of flow and has an inner designed as a cone seat flow channel and a here between its closed and open position longitudinally displaceable, in the locked position in the Conical seat of the tap housing lying, also frustoconical closure orgaa, which in Open tion position becomes effective as a compensator and its Guide piston together with the return spring and opening handle are arranged outside of the flow channel or the beer flow.

With such a design according to the invention of a tap for wheat beer, the flow channel τοη is not only achieved while dispensing with conventional cocking plugs or valve pistons and the relevant sealing seat disturbing, leading to eddy and foam formation to keep components free and a sufficiently high pressure to secure the expansion capacity of the expansion joint, but also for the closing function of the tap and the Compensation function only one organs - that frustoconical closure and compensator organ - to have to provide in the tap.

The guide piston of the closure and co-capacitor element is designed and arranged in such a way that the pressure of the beer stream acts on him in the closing direction. Offshore

the return spring secures the closed position, the • on the front side in the guide piston within a pot-shaped Recess is arranged and on the one hand the spring force via a spring cup on the tap housing transmits and on the other hand to an adjusting nut acting as a stop for the variable limitation of the opening stroke of the closure and compensator organ is applied.

The preferably designed as a toggle lever on the Tap housing supported opening handle enables Via a front side protruding from the guide piston, spring cup and spring penetrating and the Screw bolts carrying the adjusting nut allow the locking and compensator members to be opened by moving them longitudinally in the direction of flow or against the spring force of the return spring.

The essential effect sought and achieved with the invention becomes apparent when the compensator tap is opened. It forms in the flow channel in a conical annular gap that is increasingly widened in the direction of flow, as a result of which the beer flow changes into a corresponding annular, laminar flow course with increasing enlargement or diffusion of its annular cross-section. In connection with a flow-optimized compensator tip and a correspondingly shaped, ventilated outlet pipe at the outlet end of the tubular tap housing, such a flow guidance causes a gentle pressure reduction due to the friction and a gradual increase in cross-section, whereby vortex and foam formation and also a break in the beer flow cannot occur ^tei * i '.he tapping volume of about 2 liters per minute, a pressure reduction to 3 bar.

The new compensator tap offers practical use the advantages that are compared to «m their known Closure organs in the annular gap no deposits can form «that it closes automatically by spring force, that it can be easily disassembled can and easy cleaning, maintenance or repair is made possible, and that it is due to the adjustability the compensator stroke of each dispensing system can be specifically adapted. 10

The invention is shown in the drawing, for example, in a longitudinal section.

When the opening handle 1 is operated in the direction of the arrow 10, the closure and compensator element 2 is shown in FIG Direction of arrow 11 axially displaced and thereby between the conical seat-like flow channel of the tap housing 6 and the frustoconical closure and compensator member 2, an annular gap is formed and the flow released in the direction of arrow 12. Here is de? Annular gap dimensioned so that the beer flow is present as a laminar flow in its entire area. The area ratio of the annular gap expansion joint is chosen so that a break in the beer flow cannot occur.

The Stellaiutter 3 serves as a stop and limits the stroke of the closure and compensator organ 2 in the direction Tön arrow 11. By adjusting the nut 3, the stroke of the ring gap width in the open position is changed at the same time and the required pressure drop or flow rate.
