Title: Fuel distribution arrangement of a gas turbine engine
IPC: F02C7/228
Filed: 1975-09-17
Abstract: 1504348 Gas turbine engine fuel control systems V P DMITRIEV A M POLYAKOV A G TOMILIN AND S M SHUSHPAN 17 Sept 1975 38285/75 Heading F1G. The invention relates to a fuel supply system for a gas turbine engine, fuel being supplied to a pilot fuel manifold 8 having pilot burners 9 and to a main fuel manifold 5 having main burners 6. Fuel is supplied by a pump 30 to a metering device 4 comprising a metering valve 17 movable in a valve chamber 18, fuel discharging to line 3. The line 3 is connected through line 7 and valve 32 to the pilot manifold. The line 3 also connects through line 2 to a distributer 1 which comprises a fixed orifice 11, a spring-loaded valve 12, and a speed-controlled valve 13. At engine starting, fuel passes through lines 3, 7 to the pilot burners 9, also through lines 3, 2 and orifice 11 to the main burners 6 which are thus primed, the valves 12 and 13 both being closed at this stage. As the engine accelerates, the compressor discharge pressure increases, the metering valve 17 opens to allow increased fuel flow, the valve 12 opens against the loading of spring 15 whereby fuel now flows to the main burners 6. As the engine speed reaches a predetermined value, the valve 13 opens and fuel now passes through the valve 13 to the main burners, in effect by-passing the valve 12 and the orifice 11. The metering valve 4 is controlled in dependence on compressor discharge pressure P 2 , compressor inlet pressure P 1  and engine speed. Pressure P 2  is transmitted through line 25, chamber 24 and line 23 to the interior 22 of bellows 20 which is disposed in chamber 21 to which pressure P 1  is conveyed. As P 2  increases, the lower wall of the bellows moves downwardly whereby the metering valve 17 moves upwardly to increase fuel flow in lines 3, 2. Upon overspeed sensed by device 28, the valve 27 opens to allow pressure P 2  in chamber 24 and so in bellows chamber 22 to fall causing metering valve 17 to move to reduce fuel flow. The construction of the valve 12 is shown in detail in Fig. 2 (not shown) the valve comprising a sensor 41 responsive to ambient temperature which operates so that as ambient temperature falls, the spring force acting to open the valve is reduced whereby the fuel pressure required to open the  valve is increased. The increased fuel pressure causes the swirl type pilot burners to correctly atomize the fuel whereby starting of the engine at low ambient temperature conditions is improved. The converse action occurs when ambient temperature increases.

Each satellite receives the produce of at least one well through a line 26 and comprises a shell 76 housing apparatus for separating oil and water from the gas in said produce. The apparatus includes a heat-exchanger within a low-temperature gas and oil separator 32 and a threephase separator, or "knockout section" 38, the water escaping therefrom through a line 40 into the ambient water, a storage tank (not shown), or a line 44 for the oil that has passed from the separator through the heat-exchanger. The gas flows from the separator 38 through a variable choke 48, which regulates the flow and causes condensation of residual liquid as it enters the separator 32. The line 44 and a line 52 for the gas are comprised in the line 16. Glycol, or methanol may be injected through a line 54 to prevent hydrates forming. A "pig" may be injected at 62 to remove any paraffin wax deposited in the line 44. In the separator 38 oil and water gravitates into a compartment 90 whence the oil overflows into a compartment 88 screened from above by a guard 94. Valves 102, 104 are controlled by floats 106, 120. A choke 122 regulates the oil flow. The gas passes through mist extractors 124, 144. A float 150 controls a valve 146. A fail-safe valve 78 adjacent a manually-operated valve 28 is supplied with hydraulic fluid by a pump 80 from a reservoir 166. Level-sensing elements 158, 160 in the separator 32 render the apparatus inoperative in event of the oil surface 82 becoming unduly high or low. The glycol is stored in a reservoir 56. Condensate forming on the exterior of the separator 32 is collected in a sump 164. The separator 32 may be simplified so that the oil and water are not separated from each other. A second embodiment, Fig. 3 (not shown), differs in that a secondary heat-exchanger is provided between the lines 26 and 52.

Abstract: 1,080,722. Hydraulic couplings. SCHWITZER CORPORATION. Sept. 22, 1964 [Sept. 27, 1963], No. 38624/64. Heading F2C. To control slip in a coupling of the fluidshear type used, e.g. to drive the cooling fan of an I.C. engine, a flow-directing plug 39 in an elongated slot (40), Fig. 1 (not shown), connecting a liquid reservoir 23, Fig. 2, with the working chamber 24 of the coupling, is moved by heat, speed &c. variations between a position in which it extends into the liquid in the working chamber, and thus directs liquid therefrom through the slot (40) into the reservoir so as to increase the slip, and another position where it lies inside the reservoir 23, and thus permits liquid to flow into the working chamber 24 and decrease the slip. With decreasing slip, the radial depth of the liquid in the working chamber 24 increases and overlies the plug 39 &c. The radial position of the plug 39 &c. is determined so as to obtain a required minimum slip in the coupling under working conditions. As shown, the plug 39 is carried on the end of a bimetallic strip 34 which, with increasing temperature, withdraws the plug into the reservoir 23. Alternatively, the plug 39 may be speed controlled as described in Specification 1,036,231. The coupling comprises an input shaft 12 fast with a disc 26 having holes 32 through which toroidal liquid flow takes place to assist heat dissipation, and has facings 28, 51. The surrounding working chamber 24 is formed in a hub 10 to which an engine cooling fan can be bolted. Cooling fins 10a (18a) are provided on the hub and the wall of the reservoir. The liquid used is preferably silicone oil.
