ABSTRACT:
A device for tapping beer or the like from cans comprises a housing with an outlet closable by a tapping valve and an air pump. Attached to the housing is a piercing pipe which can be introduced into the can and forms a beer discharge channel which is in communication with the outlet. The air supplied by the air pump flows separately from the beer through lateral air outlet openings of the piercing pipe into the can above the level of the beer and applies pressure to the beer. The flow cross-section of the beer discharge channel in the piercing pipe is determined substantially throughout its entire length by the internal diameter of this pipe. A thin-walled sleeve of smaller external diameter than the internal diameter of the piercing pipe which separates the beer discharge channel from the flow path of the supplied air and which is sealed relative to this channel below the air outlet openings is provided in the upper region only of the piercing pipe.
