Pressure regulating valve for controlling the pressure at which a pressurized propellant gas is injected into a container containing a liquid for driving said liquid out of the container, said valve comprising: A first and a second polymeric shells, the first shell comprising a gas inlet and outlet
Pressure regulating valve for controlling the pressure at which a pressurized propellant gas is injected into a container containing a liquid for driving said liquid out of the container, said valve comprising: A first and a second polymeric shells, the first shell comprising a gas inlet and outlet openings, and the second shell containing means for resiliency biasing. A polymeric membrane, clamped between the first and second shells, thus defining a first and a second chambers sealingly separated by the membrane. A joint between the first and second polymeric shells, strong enough to withstand the pressures reigning in either chamber and ensuring fluid tightness between the two chambers; wherein, all polymeric components of said pressure regulating valve are made of the same polymer class.

1. A beverage dispensing apparatus for dispensing a beverage, said beverage dispensing apparatus comprising: a container for receiving a beverage,a pressure regulating valve, anda gas bottle or cartridge containing a pressurized propellant gas in fluid communication with said pressure regulating valve,wherein, the pressure regulating valve comprising: a first and a second polymeric shells, the first shell comprising a gas inlet and outlet openings, and the second shell containing a resilient biasing element,a polymeric membrane clamped between the first and second shells, thus defining a first and a second chambers sealingly separated by the membrane, the polymeric membrane cooperating with the resilient biasing element and the gas inlet to control a pressure at which said pressurized propellant gas is injected into the container for driving said beverage out of the container, anda joint between the first and second polymeric shells, strong enough to withstand the pressures reigning in either chamber and ensuring fluid tightness between the first and second chambers; andwherein, all polymeric components of said pressure regulating valve are made of the same polymer class. 2. The beverage dispensing apparatus according to claim 1 wherein said beverage dispensing apparatus is a disposable, home beverage dispensing apparatus. 3. The beverage dispensing apparatus according to claim 1, wherein the joint between the first and second polymeric shells of the pressure regulating valve is ensured by an over-injected polymeric ribbon running along the whole length of the joint between the first and second polymeric shells and the membrane, said polymeric ribbon being made of the same polymer class as the other polymeric components. 4. The beverage dispensing apparatus according to claim 3, wherein each of the first and second shells of the pressure regulating valve comprises a rim, and wherein said rim or a peripheral edge of the membrane have a specific structure for allowing the polymeric ribbon to anchor the components together and to sealingly embed the peripheral edge of the membrane. 5. The beverage dispensing apparatus according to claim 1, wherein the resilient biasing element of the pressure regulating valve comprises at least one of a helicoidal spring, an elastomeric bloc, and a hydraulic actuator. 6. The beverage dispensing apparatus according to claim 1, wherein a polymer class is selected from a group consisting of polyolefins, polypropylene, polyethylene; polyamides; polystyrenes, and polyesters. 7. The beverage dispensing apparatus according to claim 1, wherein the pressure regulating valve is suitable for generating a pressure difference between gas flowing in and gas flowing out is about 100 bar. 8. The beverage dispensing apparatus according to claim 1, wherein the container comprises a closure, and wherein one half shell of the pressure regulating valve is an integral part of said closure. 9. The beverage dispensing apparatus according to claim 2, wherein the beverage dispensing apparatus comprises a chime and, wherein one half shell of the pressure regulating valve is an integral part of said chime. 10. The beverage dispensing apparatus according to claim 1, wherein the membrane of the pressure regulating valve comprises means for obturating the inlet opening when the pressure in the first chamber is above a given pressure limit value, said means having a surface which is brought into sealing contact with a matching surface of said inlet opening when the resilient biasing element is compressed over a given value related to said pressure limit value.
