The installation module consists of a tubular (hollow) shaft 1 rotating Teflon bushings 2 legs 3. In the module next to the supports rigidly on the shaft radially on the same level there are two double-sided led 4, the ends of which have openings with plugs, which are inserted into the trunnion axis 5. On the axis 5 freely in the bushings mounted in pairs four of the lever 6, the respective ends of which are kinematically connected to the two stretch marks 7 and by means of four rods 8 are connected with the cross-piece 9 mounted in the center at the end of the rod 10 of the piston pump 11 double-acting with the piston 12. The piston pump has two suction valve 13, protect against clogging of the mesh 14, and two injection valve 15, the pressure cavity 16 of the pump through the pipe piece 17 is hydraulically connected to the tubular shaft 1. The axis of the pump 11 is in the same plane with the axis 5 of the sailing of the valves. The rod 18 Poppet valves are held against arbitrary fall restrictive ring 19. On the axis 5 is fixed bivalve sailing blades 20 of durable, dense, hydrophobic fabric. The length of the blades 20 is greater than the length of stretch marks 7. The ends of the blades 20 cover elastic cord 21 and restrictive cable 22 connected with the ends of the levers 6. Length of cable equal to the length of the sail cloth blades. Shafts 1 modules 23 are rigidly interconnected by a coupling 24. In building 25 hydroelectric installed generator 26, a multiplier 27, bevel gear 28 and other equipment. The connection of the discharge pipe 29, the feed water in the water tower 30 with the shaft 1 hydropower plant, carried out through the cuff 31.

The device operates as follows. Blade installation rotate counterclockwise. In the upper position the leaf blades under the action of the water stream is closed (pressed), the piston 12 of the pump 11 is in the right condition, from the rod end (right) water displaced into the tubular shaft 1, the left podpornega cavity completely filled with water. Upon further rotation under the action of a stream of water sailing blades 20 thibaudia down, as their length is greater than the length of stretch marks 7, up to the full tension of the cable 22, formed a force F5 and F6creating torque to the shaft. Upon further rotation of the flow of water penetrates between the wings of the blades, the blades open, the force is transferred to the cross-piece 9 and the piston pushes the water from podpornoy cavity in the rod cavity water is absorbed, and the blades are formed force F7. In the lower position of the sash fully disclosed, it turns out the highest power of F1and maximum torque. Upon further rotation under the action of water flow sash begin to emerge, sailing blades thibaudia up and formed a force F3and F5creating torque. The folding and opening of the valves causes the working piston pump double action. A series connection of modules 23 achieve a uniform arrangement of the blades in a spiral through the same angles. Torque is transmitted from the large bevel wheel mounted on the hollow shaft 1 on the small wheel, and thence through the multiplier 27 to the generator 26, to generate electricity. Injection pumps water through the sleeve connection 31 to the pipe 29 is supplied to the reservoir 30 and the consumer.
