Title: Fuel systems for gas turbine engines
Inventor: BLOOOM JOSEPH LEWIS
IPC: F02C9/00
Filed: 1967-05-24
Abstract: 1,237,369. Gas turbine engine fuel systems. JOSEPH LUCAS (INDUSTRIES) Ltd. July, 8, 1968 [May 24, 1967], No.24150/67. Heading F1G. The invention relates to a device for controlling the flow of fuel to a gas turbine engine, the device being of the kind comprising a tubular member 11 through which fuel must flow to the engine, the member having at least one aperture 14 in its wall, there being a fixed sleeve 10 within which the member is axially slidable in response to changes in an engine operating parameter, such as compressor pressure, and an axially slidable sleeve 12 surrounding the tubular member, the slidable sleeve being movable by a speed responsive governor 13. The arrangement is such that the axial position of the tubular member 11 and the slidable sleeve 12 determines the effective area of the aperture 14 exposed between the two sleeves through which fuel can flow to the engine. In accordance with the invention the tubular member 11 is arranged to be rotated by a part 17 rotatable with the engine, the tubular member and the part having interengaging portions which move relatively to one another as the member is rotated, the member and the part being rotatable about axes which are substantially parallel but are offset from one another so that their speeds of rotation differ. In the embodiment shown, the external surface of the tubular member 11 remote from the end which is connected to the pressure responsive means is formed with external teeth 16 of substantial axial length whilst the part 17 by which the tubular member is driven comprises a cylindrical portion formed with internal teeth 19, the axis of rotation of the part 17 being parallel to but slightly offset from the axis of rotation of the tubular member 11. Thus the part 17 and the tubular member 11 driven thereby rotate at different speeds and thus move relatively to one another when the engine is operating. In a further embodiment (not shown), the axes of the tubular member 11 and the part 17 are relatively inclined, the part 17 carrying a spider with antifriction driving elements carried on it, the elements engaging in respective internal longitudinally-extending grooves in the tubular member.
