Patent GB-877154-A (GB)
Title: Pressure ratio responsive device
IPC: G01L13/02
Filed: 1959-03-23
Abstract: 877,154. Fluid-pressure gauges. BENDIX CORPORATION. March 23, 1959 [March 24, 1958], No. 10002/59. Class 106 (2). [Also in Groups XXVI and XXIX] A device responsive to the ratio of two pressures Pr, Po, comprises two spaced interconnected pressure-responsive members 150, 152 of unequal area mounted in a casing 130 so as to define three chambers 140, 146, 148 therein, two of the chambers 146, 148 being exposed to the pressures Pr, Po, respectively, and the third chamber 140 being exposed simultaneously to both the pressures through restricted orifices 138, 142, whereby the members 150, 152 are displaced in accordance with the ratio of Pr and Po. In a device for maintaining the Mach number of an aeroplane constant by controlling the delivery of fuel to a ram jet engine, the ram pressure, Pr, is conducted to the device through a conduit 132, and atmospheric pressure, Po, through a conduit 134. The housing 130 also contains a piston 180 controlling the delivery of fuel to the engine. The pressure to the left of this piston 180 is atmospheric, and the pressure, Px, to the right of it is between the atmospheric and ram pressures, the actual value depending on the sizes of a fixed orifice 160 and of an adjustable orifice 166, controlled by a valve 170 connected to move with the pistons 150, 152. The device operates to maintain a predetermined Mach number, dependant upon the sizes of the various orifices and of the pistons 150, 152. If the Mach number increases, the piston assembly and the valve 170 will move to the right, thus opening the orifice 166 and reducing the pressure Px. This results in a decrease in the rate of delivery of fuel to the engine. Similarly, if the Mach number decreases, the pressure Px is increased, thus increasing the rate of delivery of fuel. Since the valve 170 has equal pressures acting on either side of it, there is no damping effect and an instantaneous on-off control results. In order to provide an indication of the variations in Mach number, an indicator may be driven by the piston and valve assembly. In another embodiment, Fig. 2 (not shown), the pistons 150, 152 are replaced by slack diaphragms and the valve 170 has atmospheric pressure acting on one side of it and the pressure Px on the other, thus preventing sudden opening or closing of the orifice 166. In order to vary the value of the Mach number it is desired to maintain, the orifice 142 can be adjustable either manually or automatically by a bellows-operated needle, being then dependent upon the altitude of the aeroplane.
