Abstract: 460,320. Hydraulic turbines. ENGLISH ELECTRIC CO., Ltd., and DERIAZ, P. Oct. 30, 1935, No. 30010. [Class 110 (iii)] An hydraulic turbine has a discharge regulating valve 8 byepassing the turbine and subject to control by a meter responsive to the total flow of water through the turbine and the byepass ; the control tends to keep the rate of total flow to a predetermined constant value. The turbine regulating ring 4, which operates the shutters 5 is oscillated by the piston 1 of a servo-motor actuated by oil supplied through the governor-controlled valve 3. The piston 6 of the servo-motor operating the byepass valve 8 is actuated by oil supplied through the valve 9 which is linked by a rocking lever 10 to the piston 1 so that any movement of the shutters 5 is accompanied by a compensating movement of the valve 8. A link 20 connects the rooking lever 10 to the rocking lever 19, the ends of which are operated by the pistons 6, 18. The latter piston 18 is actuated by oil which is supplied through a valve 17 operated through links from the flow-meter 11. The first of these links includes a right and left-hand screw with an adjusting nut 12 by which the rate of flow maintained by the apparatus can be varied. The piston 18 is connected to the cylinder 15 of a dash-pot, the piston 14 of which operates a loading device 16 in such a manner that the loading spring is compressed by a movement of the piston in either direction. This returns the piston 14 and the central pivot of the lever 13 to the normal position after operation. The valve 8 may be of the type described in Specification 186,233, [Class 135], and the flow meter 11 arranged in the turbine inlet conduit may be of the type described in Specification 451,295, [Group XXIX].
