Beverage dispensing system comprising a beverage container with a beverage compartment and a pressurizing system, wherein the pressurizing system comprises a gas container comprising pressurized gas, a closure closing the gas container and a pressure regulator operative for opening the closure for allowing gas to enter into the beverage compartment from the gas container, wherein the pressure regulator comprises a regulating chamber having at least a wall part movable and/or deformable based on pressure in the beverage compartment, wherein at least one opening is provided through a wall of the regulating chamber providing for at least part of a gas passage between the regulating chamber and the beverage compartment.

Beverage dispensing system, beverage container and pressurizing system for use in a beverage dispensing system or container. Beverage dispensing system 1 comprising a beverage container 2 with a beverage compartment 3 and a pressurizing system 10, wherein the pressurizing system 10 comprises a gas container 11 comprising pressurized gas, a closure 13 closing the gas container 11 and a pressure regulator 12 operative for opening the closure 13 for allowing gas to enter into the beverage compartment 3 from the gas container 11, wherein the pressure regulator 12 comprises a regulating chamber 15 having at least a wall part 17 movable and/or deformable based on pressure in the beverage compartment 3, wherein at least one opening 24 is provided through a wall 18 of the regulating chamber 15 providing for at least part of a gas passage between the regulating chamber 15 and the beverage compartment 3.

The invention relates to a pressure control device for attachment in a pressurized fluid container separating a dispersible fluid compartment and a propellant compartment, comprising a partition wall provided with at least one passage opening; and a closing element attached to the partition wall moveable between a passage opening release position and a passage opening closing position. The invention also relates to a pressurized fluid container provided with a such pressure control device.

A pressure regulating system for a beverage container system, comprising a first compartment for containing a pressurized, in fluid communication with a surrounding space through at least a gas valve for opening and closing a passage between the first compartment and surrounding space, wherein a gas valve control system is provided, comprising a deformable and/or movable wall or wall part, wherein said deformable and/or movable wall part is operably in contact with said gas valve for opening and/or closing said gas valve, wherein a second compartment is provided at a side of the said deformable and/or movable wall part, said movable and/or deformable wall part forming a wall of said second compartment, wherein the second compartment forms a pressure regulating space and comprises a wall part formed by or comprising at least a gas permeable, liquid tight permeable wall part.
