Abstract
1,046,148. Fluid-pressure servomotor systems. ROBERT SHAW CONTROLS CO. Feb. 10, 1965 [Feb. 12, 1964], No. 5833/65. Heading G3P. A valve controlling the flow of fuel to a burner comprises a housing having an inlet 12A an outlet 13A and a diaphragm 15A controlling flow through the housing when a cock 20A is opened. Inlet pressure also flows through conduit 22A and restriction 34A to a conduit 26A which is connected to a chamber 19A to act on the back of the diaphragm 15A. The pressure in conduit 26A is controlled by a reducing valve 30A, when an on-off valve 28 is opened, the fluid flowing through the valve 30A to the outlet 13A. The outlet pressure is sensed by an orifice 43 located in a fin 41 and since the pressure sensed is inversely proportional to the velocity of the fluid, the back pressure measured at 43 is less than the pressure normally which is measured at the circumference of the outlet and thus the loading on the diaphragm is reduced over known devices.
