Abstract
1339023 Fluid pressure servosystems NORMALAIR-GARRETT (HOLDINGS) Ltd 14 Oct 1971 [28 Oct 1970] 51131/70 Heading G3P In an engine anti-icing system Fig. 7, upon manual or automatic opening of solenoid valve 40, air from duct 5 flows via 43, 45 to the main port of vortex amplifier 16 and via 11 to a pressure chamber in valve 75 where the pressure aids spring 7 in tending to close the valve. Air is also admitted via 69, 70 to the main port of vortex amplifier 71 and via 72 to a further pressure chamber in the valve where the pressure tends to open the valve. With temperature-sensing vent valves 3, 58 and pressure-sensing vent valve 55 closed, a high back pressure is maintained at the control ports of the vortex amplifiers via 47, 73 and the valve 75 remains closed. If either of valves 3, 58 opens, the loss of back pressure at amplifier 16 causes the latter to depressurize line 11, allowing valve 75 to open and admit air to anti-icing cowling 74. If valve 55 should then open, the loss of back pressure at amplifier 71 causes the latter to depressurize line 72, allowing the valve to close. Movement of the valve 75 is fed back by cam 60 to valves 62, 65 controlling the back pressure at the respective amplifiers. Pressure switch 63 closes valve 40 upon excess air pressure in the supply duct. In a modified system, amplifier 71 is omitted and pressure responsive vent valve 55 controls amplifier 16, air being admitted to the forward pressure chamber of valve 75 downstream of valve 40. In a system controlling the temperature of fuel supplied to an engine at 2 Fig. 1, when sensor 3 opens to vent air at 4, the consequent loss of control pressure at amplifiers 17, 16 allows amplifier 16 to depressurize the spring chamber of valve 6, whereupon the latter is opened by inlet pressure at 5 to allow hot air from the engine to flow through heat exchanger 21 to heat the fuel. The control ports of the amplifiers may alternatively be supplied from upstream of the valve 6, and the main port of amplifier 17 may then be supplied from the same source. Amplifier 17 is omitted in a further embodiment and a manual over-ride solenoid vent valve is provided together with a feedbank restrictor responsive to movement of valve 6 to vary the control port pressure of the amplifier.
