KEG BEER DISPENSATION DEVICE EQUIPPED WITH COMPRESSED GAS RESERVOIR Russian patent published in 2009 - IPC B67D1/04 

FIELD: food industry, equipment.

SUBSTANCE: invention proposed deals with devices for dispensation of alcoholic beverages, in particular - a household keg beer dispensation device. The device contains a keg with an internal bag filled with beer and a pressurisation system. The pressurisation system injects compressed air into the cavity between the keg wall inner surface and the internal bag forcing the beer contained inside towards the device outlet. The pressurisation system is equipped with a non-return air valve mounted onto the keg upper wall and providing for infusion of compressed air into the keg. The pressurisation system contains a compressed air reservoir mounted within the device system outside the keg. The reservoir communicates with the keg non-return valve providing for delivery of at least part of the compressed air contained in the reservoir into the keg through the non-return valve in the beer dispensation mode. The device may be equipped with a pressure measurement system that enables monitoring of the keg interior pressure change rate. The device is also equipped with a signalling unit that generates a signal correlating with the volume of beer currently contained in the keg based on the available information on the keg interior pressure change rate. The technical effect consists in enhanced energy efficiency of the device combined with improved serviceability.

EFFECT: enhanced energy efficiency of the device combined with improved serviceability.
