Device for receiving and supplying energy by movement of fluid between two reservoirs for hydraulic energy storage, comprises hollow space and pump turbine which is replaced by separate machine units

摘要

The device comprises a hollow space and a pump turbine (PT), where a spring construction (F) or a combination of the spring construction and a load construction (A), increases the pressure in a lower reservoir (R1). The pump turbine is replaced by separate machine units, particularly a separate turbine and a separate pump.
