HYDROPNEUMATIC HYDROELECTRIC POWER PLANT
专利汇可以提供HYDROPNEUMATIC HYDROELECTRIC POWER PLANT专利检索，专利查询，专利分析的服务。并且In a fixed weir set up in surface water there is provided at least one inner shaft (1) which may be connected, at the vicinity of the water bottom, by passage openings closeable by means of closing members (2, 3), both with upstream water and downstream water. In the shaft (1) a sufficiently heavy float (4) is displaced and actuates by its displacements in height and in depth a work cylinder (8) acting as a double acting piston pump on the liquid tank of a hydropneumatic pressure accumulator (30). The liquid under pressure (10) thus taken to a high pressure is fed to a flow machine, preferably a turbine (20) where it is expanded. The flow machine may preferably drive an electric generator. For the liquid under pressure (10) there is provided a close cycle which brings said pressure liquid from the flow machine directly to the suction side of the work cylinder (8) acting as a piston pump.，下面是HYDROPNEUMATIC HYDROELECTRIC POWER PLANT专利的具体信息内容。
