Abstract

802,923. Gas turbine plant; speed governors. HOBSON, Ltd., H. M. Dec. 7, 1956 [Dec. 9, 1955], No. 35467/55. Addition to 712,646. Classes 57 and 110 (3). [Also in Group XXIX] The fuel supply apparatus for gas turbines described in the parent Specification is modified by arranging that the speed governor is adjustable to reduce the controlled speed to a value such that the governor is operative on the metering valve 26 to control the flow of fuel to the engine at a speed below the upper limit of the speed range in which the over-fuelling valve 22 is effective to restrict the fuel flow. To provide adequate pressure to operate the metering valve at the minimum controlled speed, the left-hand side of the servo-piston 27 instead of being connected to the downstream side of the over-fuelling valve 22 is connected by a duct 53 to the inlet side of orifice 23 and hence to the delivery of the engine-driven fuel pump supplying the over-fuelling valve. Adj ustment of the loading spring 19 of the servo-control valve 18 in this case is effected by a leveroperated eccentric 51 which acts through a follower 52 on a lever 20 constituting an abutment for the spring 19.
