Abstract

666,068. Fluid-pressure servomotors ; fluid-actuated valves. ASHTON, A. C. (Rabal, A.). Sept. 9, 1948. No. 23716/48. Class 135. A valve control ling the flow o water to or fron cisterns, etc., com prises a casing 1, Fig. 1, having ar inlet 2, and an out let 9 and a valve member 25 carriec on one arm of a two-armed lever 19 The other arm o the lever 19 engage! a flexible diaphragrr 14 closing a chamber 12 which communicates with the inlet 2 through a passage 56 and with the outlet 9 through a passage 30. The passage 56 is restricted by an adjustable needle valve 60, whilst the passage 30 is controlled by a stopper 29 carried on one arrr of another twoarmed lever 22 and urged towards closure by a spring 50. The other arm of the lever 22 coacts with a plunger 36 remotely controlled through a flexible cable 47. To open the valve 25, the cable 47 is operated to depress the plunger 36 and open the stopper 29 whence pressure in the chamber 12 is relieved and inlet pressure acting on the underside of the valve 25 opens it. In a modification, the stopper is controlled by a float 65, Fig. 4, the needle valve is dispensed with and the valve 25 is mounted adjacent the outlet. In this arrangement, the rising water in the cistern closes the passage 30, pressure in the chamber 12 then builds up and the valve 25 closes.
