Abstract: System for supplying a pressurized liquid for machines for preparing beverages comprising a first cylinder (2a) and plunger (2b) assembly (2), said plunger (2b) defining inside its cylinder (2a) a chamber (5) for housing said liquid, said plunger (2b) being able to accumulate, in an active position, potential energy from the compression force applied to a fluid, said potential energy being susceptible of being transmitted as a pressure to the liquid inside said chamber (5), and it is characterized in that it comprises a second cylinder (3a) and plunger (3b) assembly (3), said second plunger (3b) defining inside its cylinder (3a) a chamber (4) for housing said fluid, said first (2) and second (3) assemblies of plunger (2b, 3b) and cylinder (2a, 3a) being associated so that the plunger (2b) of the first assembly (2) is susceptible of accumulating, in its active position, potential energy from the compression force applied to the fluid housed inside the second assembly (3).
