Abstract

701,173. Axial-flow pumps; hydraulic turbines. ENGLISH ELECTRIC CO., Ltd. July 18, 1952 [Aug. 1, 1951], No. 18192/51. Classes 110 (1) and 110 (3). [Also in Group XXIX] A hydraulic servo-motor for adjusting the pitch of propeller type blades in a hydraulic turbine or pump wherein the blades 1 are turned about pivots 1a radially arranged in a liub member 2 of the turbine or pump runner, comprises a moving cylinder 6 slidably guided within the hub by slotted flange 6c and a projection 7a on the cylinder cover 7,and a fixed piston 9 secured to the hub boss 2b by a tubular rod 17. A ported sleeve 8 secured to the cylinder 6 and slidably mounted in the rod and piston co-operates with a hollow valve plunger 15 connected by a tube 16 to the turbine or pump speed governor. Each pivot 1a is keyed to a crank arm 12 connected by pins 4, links 3 and an eyebolt 5 to the cylinder 6, so that the cylinder 6 follows up the movement of the valve plunger 15 to adjust the pitch of the blades 7 in accordance with the speed of the turbine or pump. Pressure liquid is supplied to either side of the piston through the tube 16 and ports 8a, 8b and exhausted from one side through ports 8a, hole 11b and passage 2c to the hollow turbine shaft and from the other side through ports 8b and the square-shaped section of the plunger 15 to the hollow-shaft.
