PCT No. PCT/HU85/00023 Sec. 371 Date Dec. 26, 1985 Sec. 102(e) Date Dec. 26, 1985 PCT Filed Apr. 20, 1985 PCT Pub. No. WO85/04452 PCT Pub. Date Oct. 10, 1985.In a stationary weir erected in a surface water at least one inner shaft (1) is provided which by closure members (2, 3) communicates with the upstream and downstream water levels. In the shaft (1) a sufficiently heavy float (4) is mounted for movement which by its up and down movement actuates an operating chamber (8) of a dual functioning piston pump operating in turn on a liquid chamber of a hydropneumatic pressure storage tank (13). Pressurized fluid (10) which is brought to a high pressure in this manner is supplied to a flow machine, preferably a turbine (20) and expanded and returned to chamber (8) in a closed cycle. |
