Abstract

1,044,463. Hydraulic turbines. DOMINION ENGINEERING WORKS Ltd. June 17, 1963, No. 24002/63. Heading FIT. [Also in Division G3] In a Kaplan type turbine, the runner blades 35, 36, are journalled in a rotating casing and are adjusted by a servomotor piston 39 through a piston rod 38 and links 37. The casing is formed with a reservoir 34 and the fluid pressure for actuating the servomotor piston is provided by a pump 42 in the casing driven by an electric motor 43. The pump delivers pressure fluid to a control valve 40 which controls the supply and exhaust of the fluid to opposite sides of the piston 39, movement of the valve causing movement of the piston until ports 46, 48 are closed by lands 47, 49. The valve is actuated by a cable 28, Fig. 2 (not shown), to position the blades with respect to the position of the wicket gate 20. This gate is positioned by a motor 21 with changes in the load on the turbine and the cable is actuated by a cam 26.
