Pressure reducing and regulating valve comprising a tapping mechanism for a pressure cartridge that can be attached underneath a receptacle cover

Abstract

The invention relates to a valve unit () comprising a cartridge and valve holder (), which has means () for connecting the same to a cartridge protective housing (), means () for sealingly fastening the same in a hole () that is provided for this purpose in a liquid receptacle () as well as a lateral, continuous hole (), an internal housing (), which is mounted in the cartridge and valve holder (), in which a tapping tip () and a pressure-reducing valve unit () are located at the end of the internal housing () facing the cartridge protective housing (), wherein the pressure-reducing valve unit has a pressure-regulating chamber (), wherein the pressure-regulating chamber () encompasses a connection to the interior of the liquid receptacle () via a continuous hole () in the internal housing () and the lateral, continuous hole () in the cartridge and valve holder (), which [connection] is protected or can be blocked by a non-return valve. The unit forms a valve along with the cartridge protective housing and a cartridge that is located therein, which [valve] can be incorporated into a liquid receptacle, e.g., a 5-L keg of beer, in order to maintain a pressure level in the receptacle which ensures tapping of a fresh tasting, highly carbonated beverage even at a low filling level while using little space outside the receptacle.
