Patented Mar. 20, 1951 TEMPERATURE CONTROLLED FUEL PUMP FOR GAS TURBINES Andrew William Orr, Jr., Detroit, Mich., assignor to George M. Holley and Earl Holley Application January 29, 1949, Serial No. 73,654
'10 Claims. (Cl. 10311) The object of this invention is to transfer auto-' matically suflicient heat units from a pump to keep the temperature of the fluid below a clangerous critical point.
A further object of this invention is to provide a main pump and an emergency pump combina tion such that fuel is furnished to the engine fuel control unit under conditions of partial or complete failure of the main fuel pump.
\ The figure shows diagrammatically the preferred form of my invention asapplied to a gas turbine engine.
One of the objects of this invention is to keep the temperature of the fuel being bypassed by the engine fuel control below that temperature at which vapor lock in the common pump inlet line H] or cavitation in the pumping elements would occur. I
In the figure, I is the common fuel entrance to primary pump l2 and the emergenc pump I4. I6 is a check valve in the outlet from pump 2, I8
is a safety bypass valve from pump l2 leading back to the pump inlet I0, 48 is a check valve 'in the outlet from pump 14 leading backto the pump inlet l8.
I8 is a fuel transfer pump supplying fuel from the fuel tank 82 to the main and primary fuel pump inlet line 10. 82 is a bypass valve around transfer pump 13.
.by the pressure transmitted through a passage 38 connected to a passage 40. An emergency pump [4 delivers fuel to the passage 44 and to the passage 40 through a check valve 42 whenever the unloading valve 36 closes the unloading passage 84.
A spring 46 together withthe pressure in line 2 The gas turbine 60 is provided with a compressor 62 revolving on a shaft 64 which carries the gas turbine 66. Two of the combustion chambers 6B and 10 are shown, actually there are quite a number of others. The pipe 32 is provided with burnersfor each of the combustion chambers.
The chamber 12 encloses the temperature responsive element 54. The products of combustion circulate through the chamber 12 entering passage 14 and issue out of passage 16.
Fuel supply pump 78 draws its fuel from the tank 82' into which the receiving tank 2| discharges.
Operation Assume that the emergency pump I4 is out of action, as shown, and that the normal pump 12 is supplying the fuel to run the gas turbine. As the speed increases the valve 28 closes and as the temperature of the exhaust gases increase the element 54 which is liquid filled expands and at any given revolutions per minute the speed mand of fuel valve It or if pump 92 fails, valve 30 tends to close the unloading valve 36 against the action of the pressure in passages 38 and 453.
The valve 28 may be controlled by any one of a large number of available controls. I have chosen to illustrate this invention with a conventional control consisting of a centrifugal gov- 26 closes and the lessened pressure differential between passages 38 and 30 together with spring 46 causes valve 35 to close and pump l4 supplies fuel to the fuel system. When this occurs valve 36 takes over the function of valve 26 to maintain a very slightly lower pressure drop across valve 28. If main pump [2 fails completely, pressure in line 40, from pump l4 closes check valve I 6. The check valve 42 is closed at all times when pump I4 is not delivering fuel to passage 40.
Under these conditions when pumps l2 and M are running athigh speed and valve 28 is almost closed, most of the fuel delivery is bypassed back to pump inlet ill by valve 26 through passage 34. Alternatively when pump l2'is not operating then the bypass valve 36' controls the flow through passage and pump l4 delivers fuel to the main fuel control valve 28. Either of these conditions results in the addition of considerable heat to the fuel system and a rise in temperature of the fuel in the critical inlet passage 10. When the temperature rises to a point below where vapor lock or cavitation would take place, thermostat element 86 rotates and opens the port 88 in the rotary valve 20 thereby passing fuel back to the fuel tank 80 through passage 22. Colder fuel from the tank 80 is thus brought into the system to reduce the temperature of the fuel below the critical point.
