Abstract: A beverage pressure control device, comprising a pressure regulating chamber and a pressure sensing chamber, separated by a movable or deformable wall part, wherein at least one gas inlet channel is provided for feeding gas under pressure into the pressure sensing chamber and at least one gas outlet channel for feeding gas from the gas sensing chamber, wherein the gas inlet channel can be closed by a valve operated by the movable or deformable wall part, depending on a pressure difference over said movable or deformable wall part, wherein an operating device is provided for regulating the flow through the at least one outlet channel.

Abstract: A dispensing unit for dispensing a liquid under pressure, the dispensing unit comprising a first coupling means for coupling to a liquid container adapted to store the liquid to be dispensed and a propellant gas at a first pressure and a pressure regulating means for generating said first pressure in the liquid container. The pressure regulating means have a second coupling means for coupling to a gas container adapted to store said propellant gas at a second pressure substantially higher than said first pressure and a first fluid communication path for the propellant gas between said gas container and said liquid container. Furthermore a dispensing path for dispensing the liquid from the liquid container and a first operating means for controlling the flow rate of the liquid along the liquid dispensing path during dispensing are provided.

Abstract: Container unit for beverage, comprising a beverage container with a body and a neck portion, wherein at least the body portion forms a first compartment for beverage, wherein a pressure control device is provided, preferably at least partly in the beverage container, for pressurising a beverage in the beverage container, which pressure control device comprises a gas container forming a second compartment for containing a propellant under pressure, wherein a dispensing unit is provided in and/or on the neck portion and the gas container is supported by the neck portion and/or the dispensing unit, wherein pressure regulating means are provided in the dispensing unit.
