Abstract
783,984. Fluid-actuated valves. AVERYHARDOLL, Ltd. Nov. 24, 1955 [Feb. 24, 1955], No. 5587/55. Class 135. A valve controlling liquid flow from 21 to 29, comprises a main valve 24 controlled by a pilot valve 36 varying the pressure in a control chamber 27 which tends to close the valve while the pressure upstream of the valve tends to open it, the pilot valve when moved to connect the chamber 27 to the downstream side via passage 37, cutting-off the chamber from the upstream side via passage 34, and means, e.g. the venturi 47, whereby liquid flow through the valve applies suction to the chamber. The pilot valve is initially lifted to open the downstream and close the upstream connection to the control chamber by a crank 42 and shaft 43 connected to a hand lever 52, the latter also setting a flow meter 10 when a hand lever pawl 57 engages a stop 58 on a lever 53 loose on shaft 43 and connected to the meter. The pressure differential across piston 25 opens the main valve, the opening movement being increased by venturi suction applied to the chamber via passage 37. The pilot and main valves may be lowered to stop flow either by the meter acting on the hand lever through the pawl and stop 58 or by movement of the hand lever alone so that the pawl 57 snaps under a stop 59 on lever 53. Specification 737,696 is referred to.
