Abstract
825,403. Fluid-pressure servomotor-control systems. EKSTROMS MASKINAFFAR A.B., A. April 29, 1957 [April 27, 1956], No. 13641/57. Class 135. A regulator for maintaining a constant pressure or pressure difference and suitable for controlling the air or gas supply to combustion apparatus comprises a diaphragm 306 clamped between upper and lower casing members 302, 301 and sandwiched between upper and lower plates 305, 303 of which the latter is pivotally mounted on a shaft 304, a link 325 connecting the diaphragm to a control valve 323, and a restoring device consisting of pistons 311, 312, subject to the output pressure from the control valve and acting through a diaphragm 308 on the diaphragm 306 in a restoring sense. The arrangement shown is suitable for controlling a pressure supplied to the lower side of the diaphragm 306 through a conduit 331, this pressure being balanced by an adjustable spring 326 Any deviation of the control valve 323 from its neutral position shown causes pressure fluid to be supplied from a conduit 321 to a conduit 329 or to be exhausted from the latter depending upon the direction of movement of the valve. The pressure in the conduit 329 is fed through a conduit 330 to a servomotor (not shown) operating a draught valve or varying the speed of a flue gas fan. Variation of the pressure in the conduit 329 also causes movement of the pistons 311, 312 whereby the pressure above the diaphragm 308 is varied in a sense to oppose the deflection of the diaphragm 306. A bleed 318 below the piston 311 enables the pressure below the piston 311 gradually to be restored. A bleed 319 above the piston 311 discharges leakage past the piston 312. The diaphragm 306 may be replaced by a bellows as also may be the pistons 311, 312. In a modification, for controlling the pressure difference across an orifice plate, the two pressures are connected to opposite sides of the diaphragm 306 and the valve 323 is actuated from a point opposite the diaphragm 308, the connecting-link for the valve passing through a diaphragm in the lower part 301 of the housing.
