    • 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). Method for supplying pressurized liquid comprising the following steps: a) moving by continuous or discrete steps the plunger (2b) of said first assembly (2) to an active position in which said plunger (2b) accumulates potential energy from the compression force applied to the fluid housed inside the chamber (4) of the second assembly (3), b) charging liquid from a tank (14) in the chamber of the cylinder (2a) of said first assembly (2), said charging being done preferably during step a), when the plunger (2b) of the first assembly (2) is moved, the inline valve (15a) of the liquid distribution duct (11) remaining closed during said charge, and c) driving the push-button (16) associated with the liquid distribution duct (11) for opening the inline valve (15a) of said duct (11) and permitting the exit of pressurized liquid.

    • A variable displacement swash plate type compressor includes a rotary shaft, a tiltable swash plate, a movable body that is coupled to the swash plate and changes the inclination angle of the swash plate, a link mechanism that permits the inclination angle of the swash plate to be changed, a first support portion provided to the movable body, a second support portion provided to the swash plate, and a first coupling member that couples the first and second support portions to each other. The second support portion is pivotally supported by the first coupling member. The swash plate has top and bottom dead center associated parts for positioning each piston at top and bottom dead centers, respectively. The top and bottom dead center associated parts are arranged with the rotary shaft in between. The second support portion is arranged between the top and bottom dead center associated parts.

    • In an embodiment, a variable flow pump may include a swashplate rotatably driven by a driveshaft. The swashplate may be movable between a first and second tilt angle relative to the driveshaft. A piston pump may be reciprocatingly driven by the swashplate based upon, at least in part, the tilt angle of the swashplate. An actuator piston may be moveable between a first and second position based upon, at least in part, a downstream backpressure of a fluid pumped by the piston pump. An actuator assembly may be moveable between a first and second position based upon, at least in part, the position of the actuator piston. The actuator assembly may include a swashplate driver configured urge the swashplate between the first and second tilt angles, and a biasing driver configured to apply a force urging the swashplate into contact with the swashplate driver.

    • A hydrostatic positive displacement machine (2) is operated in a closed circuit and delivers hydraulic fluid into a working circuit. The displacement volume is varied by a control device (6) having a variable displacement piston device (7). The machine (2) has a swivel-back device (40) which, in the event of a decrease of the feed pressure from the feed pressure source (11), guarantees actuation of the machine (2) toward a reduction of the displacement volume. The swivel-back device (40) includes at least one pressure sequence valve (41), which is in communication on the input side with the working circuit of the machine (2). In the event of a decrease in the feed pressure from the feed pressure source (11) below a limit pressure, the pressure sequence valve (41) makes it possible to supply the control device (6) of the machine (2) with hydraulic fluid from the working circuit.
