The patent US12062969B2 describes a fluid plant designed for fluid installations, particularly focusing on natural gas delivery systems. The fluid plant includes a high-pressure line and an expansion system that converts high-pressure fluid into low-pressure fluid. Central to the design is an electricity generating system that utilizes a double-acting cylinder to alternately supply high-pressure fluid, transforming mechanical translational energy into mechanical rotational energy through a hydraulic system. This energy is then converted into electrical energy by an electric generator. The system is equipped with an electronic control unit that manages the supply of high-pressure fluid to the double-acting cylinder and incorporates solenoid valves and multiway distribution valves for efficient operation.

Additionally, the fluid plant features an electrical energy accumulator to store direct current generated by the electric generator. The design includes a metering device positioned downstream of the expansion system, which is also powered by the electricity generating system. The patent outlines the structural components of the double-acting cylinder, including a piston that separates the internal volume into two chambers. The expansion system is engineered to maintain a specific downstream pressure, ensuring optimal performance. Overall, the fluid plant serves as a crucial component in connecting transport and distribution networks for natural gas, enhancing the efficiency and reliability of fluid installations.
