Abstract
760,629. Fluid-pressure servomotor control systems. VICKERS-ARMSTRONGS (ENGINEERS), Ltd. March 23, 1955 [May 24, 1954], No. 15289/54. Class 135. The output of a feed-water pump for a boiler is regulated by means including a chamber 13 in communication with the boiler steam outlet pipe 1, a valve device 2 which controls the quantity of steam flowing to chamber 13 in accordance with the steam flow through pipe 1, a controlled exhaust outlet 17 from the chamber, and means to vary the feed-water pump output in accordance with pressure variations in the chamber. A hinged vane 9, urged to the vertical position by its own weight, takes up a position according to the steam flow through pipe 1 and so varies the degree of opening of a pair of rotary cylindrical valves 2 carried one at each end of the hinge pin of the vane. The outlet 17 is controlled by a plug valve which is set by hand to vary the area of the vent provided. The pressure in chamber 13 is applied to the underside of a piston 24 where it acts in opposition to a spring 31 which loads towards the open position the valve 26 carried by the piston. Valve 26 controls the steam supply to a turbine driving the feed-water pump.
