Apparatus for preparing beverages comprising a module (10) for distributing a beverage by supplying a pressurized liquid, a liquid supply tank (7), gas supply means (65) configured to supply the module with pressurized liquid, a liquid feed chamber (80), the said chamber being arranged, in a filling configuration, to communicate with the tank (7) in order to be filled with liquid and the said chamber being arranged, in a module supply configuration, to communicate with the gas supply means in order to pressurize the liquid in the chamber and to distribute a quantity of liquid under a certain pressure through the module. Preferably, the chamber (80) is bounded by at least one elastic wall (85), separating the gas from the liquid in a sealed manner and, configured to deform elastically and thereby reduce the internal volume of the chamber under the effect of the gas thrust against this wall. The invention applies, for example, to mobile or portable coffee or multi-beverage machines.

Apparatus according to claim 1, wherein the liquid feed chamber comprises a liquid inlet associated with a one-way valve configured to retain the liquid in the chamber after the chamber is filled. 3. Apparatus according to claim 1, wherein the wall has a sufficient elasticity to be able to suck the liquid from the tank into the chamber up to a liquid level in the chamber that exceeds a liquid level in the tank. 4. Apparatus according to claim 1, wherein the wall is made from a material selected from the group consisting of an elastomer and silicone. 5. Apparatus according to claim 1, wherein the elastic wall is tube-shaped and surrounds the chamber in a sealed manner. 6. Apparatus according to claim 1, wherein the elastic wall is surrounded by the rigid tubular body, the rigid tubular body comprising at least one gas inlet. 7. Apparatus according to claim 1, wherein the external surface of the elastic wall is in contact with the internal surface of the tubular body. 8. Apparatus according to claim 1, wherein the rigid tubular body comprises a plurality of peripherally spaced gas inlets. 9. Apparatus according to claim 1, wherein the module comprises a housing suitable for receiving a packed portion of food substance and a liquid injection device for injecting the pressurised liquid from the chamber through the packed portion of food substance. 10. Apparatus according to claim 1, comprising valve means which are moveable in at least two positions to act: a) in a chamber liquid filling and/or rest position, by cutting off the gas supply that exerts a force against the wall; andb) in a supply position to send the pressurized liquid into the module by placing the gas supply in thrust configuration against the elastic wall. 11. Apparatus according to claim 10, wherein in the supply position, an entire volume of the chamber is expelled under pressure and the chamber is completely emptied of its volume of liquid whenever placed in the supply position by the valve means. 12. Apparatus according to claim 1, wherein the chamber is located inside the liquid tank. 13. Apparatus according to claim 12, wherein the tank comprises thermally insulated walls. 14. Apparatus according to claim 1, wherein the gas supply pressure is between 2 and 25 bar. 15. Apparatus according to claim 14, wherein the gas is selected from the group consisting of compressed air, CO2, N2, N2O, argon, and mixtures thereof. 16. Apparatus according to claim 1, wherein the chamber has a volume corresponding to the maximum volume of the beverage to be produced. 17. Apparatus according to claim 1, wherein the chamber has a volume of between 40 and 1000 cc. 18. Liquid pumping device for supplying pressurized liquid to a beverage distribution apparatus comprising: a rigid tubular body comprising a gas supply inlet,a chamber for receiving the liquid,a liquid inlet communicating with the chamber,a liquid outlet communicating with the chamber from which the liquid is expelled under a certain pressure,the chamber being defined by a core of the liquid pumping device and at least one elastic wall, the elastic wall separating the liquid from the gas supply in a sealed manner;the wall being configured to deform elastically and thereby reduce the internal volume of the chamber under the effect of a gas thrust against an exterior of wall, the reduction in volume of the chamber driving the liquid through the liquid outlet, the wall is mounted on a core to define the chamber, and the rigid tubular body is positioned against the wall with ends of the tubular body engaged to corresponding ends of the core to form, between the internal surface of the tubular body and the external surface of the wall, a zone into which the gas is blown under pressure through the gas supply inlet, the rigid tubular body comprising the gas supply inlet, andthe device is so constructed and arranged to be filled by a suction created by the wall which has a sufficient elasticity enabling it to return to position when the gas stops deforming the wall and to create a vacuum in the chamber in order to suck the liquid into the chamber through the liquid inlet and thereby to fill the chamber with liquid, the device comprising closure means for retaining a constant volume of sucked liquid in the chamber up to its forced expulsion by the wall under the effect of the gas pressure. 19.
