摘要

The present invention provides a dispensing unit (1), which is designed to be arranged on a predetermined beverage keg (10), and a combination with the beverage keg and a method for tapping a beverage until complete emptying by means of the combined arrangement of dispensing unit (1). and beverage keg (10). Here, the nozzle attachment (1) has a base body (2) with fastening element (2 '), a connection device (15) for a gas source (16), and a first valve arrangement (13) and a gas channel (5 "), wherein the first Valve arrangement (13) the gas passage (5 ") between the connecting device (15) and its mouth (50) opens or closes. The tap attachment (1) further has a second valve arrangement (3) and a riser channel (8) and a tap (9) with outlet (8 '), which is connected via the second valve arrangement (3) with the riser channel (8). The tapping attachment (1) further comprises a gas-tight expansion device (4) surrounding the gas passage (5 ") at its mouth (50) .The expansion device (4) is expandable by supplying gas from the gas source (16) and adapted to in the expanded state, it has a volume which corresponds at least to an internal volume of the predetermined beverage barrel (10) onto which the dispensing attachment (1) can be placed A stabilization device which is designed as a gas supply tube (5) with an internal channel (5 ') is that continues the gas channel (5 ') is surrounded by the expansion device (4) and stabilizes the expansion device (4) during expansion.
