Abstract

454,148. Fluid-actuated valves. GODFREY, R., 214, Stockport Road, Cheadle Heath, Stockport. Dec. 21, 1934, No. 36762. [Class 135] A device for maintaining a constant flow of fluid despite pressure variations on its delivery side comprises a flexible diaphragm 11 having an orifice 15 therein or in a member carried thereby, through which orifice fluid flows to a controlling valve member 1 actuated by the diaphragm in accordance with the difference of the pressure on its opposite sides due to flow through the orifice. The doublebeat valve 1, Fig. 1, is connected to a ported guide member 16 which abuts the diaphragm 11 around its orifice 15. A spring 18 adjustable by means of a bolt 20 acts through a perforated guide member 7 to urge the valve open. The diaphragm is clamped between an extension 9 of the casing 6 and a cover 12 having a central inlet 14. The orifice may be formed in a member 25, Fig. 2, which can be removed and exchanged by means of a lateral opening in the casing closed by a plug 26. The member 25 is screwed into a cuplike member 23 clamped to the diaphragm. The orifice 15, Fig. 1, may be controlled by a shutter pivoted to the diaphragm. The shutter has a flexible arm slotted to receive a pin on a crank disc formed on a rotary spindle passing through the cover 12. When used to control the supply of air or gas for raising liquid in wells, the device is connected across a manuallyactuated valve which, when opened, byepasses the device to secure an adequate starting pressure.
