Apparatus according to claim 1, wherein the tank comprises thermally insulating walls. 5. Apparatus according to claim 4, wherein the insulating walls comprise at least one internal wall of material with a low specific heat and at least one insulation layer surrounding the internal wall. 6. Apparatus according to claim 5, wherein the internal wall is made of a material selected from the group consisting of glass and metal. 7. Apparatus according to claim 1, wherein the chamber is located inside the tank. 8. Apparatus according to claim 7, wherein the chamber is mechanically isolated from an impact with respect to the inner surface of the insulating walls of the tank. 9. Apparatus according to claim 1, wherein the chamber is positioned outside the tank. 10. Apparatus according to claim 1, wherein the valve means comprise a two-way valve that is manually or electrically actuated. 11. Apparatus according to claim 1, wherein the gas supply pressure is between 2 and 25 bar. 12. Apparatus according to claim 11, wherein the gas is selected from the group consisting of compressed air, CO2, N2, N2O, O2 argon and mixtures thereof. 13. Apparatus according to claim 2, comprising means for heating the liquid before it is introduced into the extraction module. 14. Apparatus according to claim 13, wherein the heating means are electrical means of the resistive type or a thermo block or means of the burner type using a fuel selected from the group consisting of solid, gaseous and liquid fuel. 15. Apparatus according to claim 13, wherein the built-in electric power supply means are provided to supply the electrical heating means and comprise at least one electric battery. 16. Apparatus according to claim 14, wherein the electrical connecting means are provided in order to supply the heating means periodically during connection of the electrical connecting means to an external electric power supply source. 17. Apparatus according to claim 1, wherein the module is a pressurized-liquid delivery module. 18. Apparatus for preparing beverages comprising: a module for delivering a beverage by supplying a pressurized liquid, a liquid feed tank of sufficient capacity for supplying the module with liquid for supplying more than one beverage, pressurizing means suitable for supplying the module with pressurized liquid, a liquid feed chamber, of which the capacity is several times smaller than the capacity of the tank; the chamber being arranged, in a filling configuration, to communicate with the tank in order to be filled with liquid and, the chamber being arranged, in a module feeding configuration, to communicate with the pressurizing means in order to pressurize the liquid in the chamber and to inject pressurized liquid into the module and thereby permit delivery of the liquid through the module, the apparatus is configured to be mobile or portable for service by being free of an electrical connection to an electrical power supply outlet during service, the pressurizing means is non-electrical and comprises at least one autonomous reserve of pressurized gas, the tank comprises heat insulated walls to reduce the liquid heat loss during transport, and wherein the tank further comprises a valve means to connect the chamber to an atmospheric pressure in a first position of the valve means and to connect the chamber to a pressurized gas in a second position of the valve means. 19. A portable apparatus for preparing beverages comprising: a module for delivering a beverage by supplying a pressurized liquid, a liquid feed tank, a liquid feed chamber, valve means that are movable in at least two positions; the chamber being arranged, in a filling configuration in a first position of the valve means, to communicate with the tank in order to be filled with liquid and in a module feeding configuration in a second position of the valve means, to communicate with an autonomous reserve of pressurized gas in order to pressurize the liquid in the chamber and to inject pressurized liquid into the module and thereby permit delivery of the liquid through the module, and in the module feeding configuration the gas enters into direct contact with the liquid present in the chamber while the tank remains isolated from the pressure with respect to the chamber. 20. Apparatus for preparing beverages comprising: a module for delivering a beverage by supplying a pressurized liquid, a liquid feed tank of sufficient capacity for supplying the module with several volumes of liquid for repeatedly supplying more than one beverage, and pressurizing means suitable for supplying the module with pressurized liquid, a liquid feed chamber, having a capacity that is several times smaller than the capacity of the tank; the chamber being arranged, in a filling configuration, to communicate with the tank in order to be filled with liquid and, the chamber being arranged, in a module feeding configuration, to communicate with the pressurizing means in order to pressurize the liquid in the chamber and to inject pressurized liquid into the module and thereby permit delivery of the liquid through the module, the pressurizing means comprises at least one autonomous reserve of pressurized gas, and in the module feeding configuration, the gas enters into direct contact with the liquid present in the chamber while the tank remains isolated from the pressure with respect to the chamber, so that the liquid present in the tank is not subjected to the gas pressure exerted in the chamber, wherein the module is an extraction module suitable for receiving a portion of food substance for the preparation of a beverage by supplying a pressurized liquid from the chamber through said substance, and wherein the apparatus further comprises valve means that are movable in at least two positions to act, in a chamber filling position, to place the chamber in the filling configuration, and in a position for feeding the module by the chamber to permit the extraction of the portion in the extraction module. 21.
