Abstract: 734,810. Gas turbine plant. GARRETT CORPORATION. April 17, 1953 [May 2, 1952], No. 10552/53. Class 110 (3). [Also in Group XXIX] A pneumatically-actuated governor for controlling the fuel supply to a gas turbine engine in dependence on the ratio of the pressures on opposite sides of the engine compressor and also on the ambient air temperature comprises a casing 26 having a chamber divided into two compartments 27, 50 by a movable wall such as the flexible diaphragm 49, a valve 33 operatively connected to the movable wall and adapted to control a passage 25 connecting the compartment 27 on one side of the wall with a fluid-pressure actuated fuel control means V, and means such as the bellows 53 for modifying the actuation of the valve 33 by the movable wall in response to changes in the ambient barometric pressure and temperature. The turbine T has a combustion chamber 10 supplied with air by the compressor C and with fuel by a nozzle 11 supplied by a pump P. The compartment 27 is exposed to the outlet pressure of the compressor by a pipe 40 and the compartment 50 is open at atmospheric pressure through a port 51. The fuel pump P has a by-pass 12 regulated by a diaphragm-actuated by-pass valve 23 controlled by the valve 33. The control chamber 19 of the by-pass valve 23 communicates by the passage 25 and a restriction 30 with a passage 29. A recess 28 below the restriction 30 communicates with a vent passage 31 adjustable by a metering valve 32. The bellows 53 comprises inner and outer walls, the space between which is charged with air or other suitable medium to detect also changes in the atmospheric temperature. The head 54 of the bellows is exposed to atmospheric pressure and is loaded by a spring 64 which can be adjusted by a ring 65 screwed into an openended sleeve 66. The sleeve is clamped in spaced relation to the end cover 48 by screws 67. The valve 33 is opened against a spring by a screw-threaded stem 55 which is adjustably connected to the diaphragm 49 and to the head 54 of the bellows.' Thus by slackening a nut 59, the stem 55 may be rotated in a nut 56 clamped to the diaphragm 49 so that the central area of the diaphragm is raised or lowered and the effective area of the diaphragm decreased or increased. The stem 55 may be raised or lowered to alter its position with reference to the valve 33 by rotation of a nut 61 mounted in the bellows head 54. The interior of the bellows is open to atmospheric pressure through the clearance 58 between the end cover 48 and the stem 55. A single-walled bellows may be used in some cases.

Filed: 1971-04-22
Abstract: 1321980 Steam generators M J BERLYN 22 April 1971 [25 May 1970] 20782/71 Heading F4A Hot vapour under pressure is produced by igniting compressed air and fuel in a combustion chamber 19 into which water is injected in dependence upon the temperature of the vapour. Air is compressed by a compressor 11 into which primary water is injected at 22 by a pump 51 driven by a cam-shaft 69 of the compressor. The air passes through 17 into combustion chamber 19 where fuel is injected at 23 by a pump 52 driven by cam-shaft 69, and ignited by a glow plug 25. Secondary water is injected at 24 by a pump 53 driven by a cam-shaft 29 of an expansion motor 12 fed through port 20 with some of the hot vapour and which is used to drive the compressor 11. A cranking motor 56 is provided for starting the compressor. Supply of vapour to the motor 12 is controlled by a valve 47 operated by a speed governor 42; a solenoid 57 ensures that the valve 47 is closed during starting. The remainder of the hot vapour is discharged through branch 21 and valves 50, 59 to an external circuit where it drives other expansion engines. The temperature in the combustion chamber 19 is controlled by a sensor 26 which actuates a cam-shaft 39 regulating the output of the fuel and water pumps 52, 53. A pressure responsive servo 27 also drives a camshaft 34 which controls the primary water and fuel pumps 51, 52 and also the spring loading of the governor 42 thereby to vary the speed of the motor 12.
