Abstract
Beverage dispensing apparatus comprising a self-regulating flow rate control means (5). It comprises: A pressurized container (30, 31) containing a beverage to be dispensed; A dispensing duct (1) defined by at least one wall and bringing in fluid communication the liquid beverage contained in the container through a first opening (1a) with the exterior via a valve (35) and out of a second opening (1b), for drawing beverage out of the container. At least a section (3) of the wall defining the dispensing duct is resiliently flexible and is such that its inner surface, facing the interior of the dispensing duct, is exposed to the pressure, P1, reigning in the duct at that level, and its outer surface, facing out of the duct is exposed to a pressure, P2, substantially equal to the pressure reigning in the container, the resiliently flexible section (3) being suitable for maintaining a substantially constant dispensing flow rate over a given range of operating pressure values, P2, in the container.
