Abstract
830,007. Gas-turbine jet-propulsion plant. BENDIX AVIATION CORPORATION. Nov. 9, 1956 [Dec. 15, 1955], No. 34358/56. Class 110 (3). [Also in Group XXIX] Control apparatus for gas-turbine engines with afterburner fuel control means 44 comprises a fluid-operated device 109 controlling fuel supply through the control means 44, and two devices controlling fluid supply to the device 109, one 65 being manually actuated and the other 79 being actuated in response to engine speed to permit fluid flow for a range of speeds above a predetermined value. A pump 36 supplies fuel through a main fuel control 34 to the main burners 26 and also up to a piston valve 64 and past a pressure regulator 126 to a cylinder 122 having a leak-off valve 120. A manual throttle lever 54 for the control 34 opens the valve 64 through a cam 56 allowing the pump discharge pressure to pass to a normally closed piston valve 79. On the engine speed reaching a predetermined minimum value set by an adjustment 140, an engine speed sensitive flyweight 112 acts through lever 116 to close the leak-off valve 120 whereby the piston 129 spring connected to the leak-off valve, moves upwards and through its cam 134 closes a leak-off valve 96 whereby the pump discharge pressure builds up beneath a piston 80. As the piston moves up, direct pump pressure is suddenly applied via passage 86 and opens the piston valve 79 to allow pump discharge pressure to pass to the left-hand side of a piston 103 which moves to open the valve 107 allowing fuel to pass through a pump 48 and fuel control 44 to after burners 50. The piston valve 79 is hydraulically locked in its raised position regardless of subsequent engine speed changes. When the lever 54 is moved to allow the valve 65 to close, pump discharge pressure is cut-off at 76 and 86 and spring 82 moves the piston valve 79 downwards to close line 98 and connect both sides of the piston 103 to pump intake pressure via pipe 110 so that spring 105 closes valve 107.
