Abstract
692,202. Gas turbine plant. DOWTY EQUIPMENT, Ltd. April 17, 1951 [April 19, 1950], No. 9655/50. Class 110(iii) [Also in Group XXIX] In a liquid fuel regulating system for aircraft gas turbine engines having burners of the spill type, the fuel supply means are regulated by a servomotor under the control of a vent valve the closure member 21 of which is movable in response to the pressure difference between the high and low pressure sides of the burners. In Fig. 1. the burners 13 are supplied from an engine driven circulating pump 11 through a pipe 12 and fuel returns to the pump inlet via a pipe 14. The pressures in the pipes 12, 14 are conveyed through pipes 28, 29 to the servomotor control means 20 which are also connected by a pipe 23 to a servomotor regulating an engine driven fuel supply pump 15 and by a pipe 24 to the inlet of the pump 15 or to a fuel tank 17. The servomotor may control a by-pass valve in the case of a fixed stroke pump or the pump stroke-varying element in the case of a variable-stroke pump. In one form, the servomotor control means 20 includes a vent valve 21. Fig. 4. controlling the leakage of fuel from the pipe 23 to the pipe 24. The valve head 21 is formed on a rod 25 carrying a piston 26 (or a diaphragm) exposed through the pipes 28, 29 to the pressure difference across the spill-burners. This pressure difference has been found to vary substantially as a function of engine speed irrespective of changes in altitude so that the apparatus described functions as an all-speed governor, the datum speed being adjusted by varying the loading of a spring 20 by a cam 31 actuated by the pilot's lever 32. In Fig. 5, the piston 26 is replaced by the opposed bellows 36, 37 connected to pipes 28, 29 respectively and acting on a lever 34 bearing a half ball valve 33 controlling the vent 22. The lever 34 is also influenced by a bellows 38 the hydraulic loading in which is varied by means of a constant speed pump 39 having a by-pass valve 40 adjusted by the pilot's lever 32.
