Abstract
694,318. Gas turbine plant DOWTY EQUIPMENT, Ltd. Sept 5, 1951 [June 5, 1950], No. 14014/51. Class 110(iii) [Also in Group XXIX] A gas turbine engine fuel system comprises an engine-driven pump 11 for feeding fuel to burners 14 of the spill type, a servo-actuated throttle valve 17 in the return line 15 from the burners, and a vent valve 27 controlling the throttle valve and actuated in the opening sense by a loading which varies in accordance with engine speed and in the closing sense by a spring 36, a manual control 38, 39 for the spring being operative to select the engine speed at which the vent valve operates to control the throttle valve. The servo-piston 18 which operates the throttle valve is loaded by a spring 23 and is subject on one side to spill line pressure in a chamber 19 and on the other side to pressure in a chamber 20 having a restricted connection 22 with the spill line and the vent connection 25. The vent valve is carried by a differential piston 29 subject to fuel pump delivery pressure in a chamber 30, spill line pressure in a chamber 31, and atmospheric pressure in an intermediate chamber 34, the pressure difference between the chambers 30, 31 varying substantially as engine speed. Instead of the liquid for actuating the servo-piston 18 being derived from the spill line it may be obtained from the pump delivery conduit 13. Also, the differential piston 29 may be subject to the pressure drop across a restriction in the conduit 13 or to the pressure generated by an engine driven centrifuge instead of the pressures in the pump delivery and spill lines. The servopiston 18 may also be controlled by another vent serving as an over-speed governor and by a further vent limiting the fuel flow in accordance with air mass flow to constitute an acceleration control. According to the Provisional Specification the vent valve 27 may be operated by pressure developed by an engine-driven auxiliary oil pump the delivery line from which has a branch terminating in a vent controlled by an adjustably spring-loaded closure member.
