Abstract: A two-phase expansion device (106) capable of maximizing the amount of movement produced by a two-phase flow. The two-phase expansion device (106) includes at least: one dispenser (105) for dispensing the fluid to a plurality of two-phase expansion nozzles (60); a plurality of adjacent two-phase expansion nozzles (60) with substantially parallel axes, each two-phase expansion nozzle (60) including sequentially at least one diffuser (65), one neck (66), and one tube (67), the two-phase expansion nozzles (60) being arranged to each receive a portion of the flow from the hot source; and elements for supporting the plurality of two-phase expansion nozzles (60) and including elements for sealably separating the two-phase expansion nozzles (60).

Abstract: Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.

Abstract: A device for storing and delivering fluids, the fluids including a gas and a liquid, the device including: at least one container (1) for storing the fluids, a gas inlet (2) and a gas outlet, an inlet and an outlet for the liquid, at least one facility (8) for injecting gas into the container (1) for storing the fluids; at least one outlet facility (9) connected to the gas outlet for evacuating the compressed gas, liquid discharging elements, and at least one motor group (15) including at least one pump (17) and at least one motor (18) for injecting the pressurized liquid into the container (1) for storing the fluids via the liquid inlet.
