摘要： High-pressure fuel is supplied at a controlled rate to a combustion chamber via a position-controlled valve and a variable-restriction stop-and-pressurizing cut-off valve. A value representative of the real mass flow rate of fuel as delivered is calculated by a calculation unit on the basis of information representative of the pressure difference between the inlet and the outlet of the cut-off valve and of the flow section through the cut-off valve, e.g. as represented by the position X of the slide of the cut-off valve. The position-controlled valve has a variable position that is controlled by the calculation unit as a function of the difference between the calculated value representative of the real mass flow rate and a value representative of a desired mass flow rate.

摘要： A direct metering fuel supply system includes a fuel pump, a burn flow fuel line, a servo flow fuel line, and a servo regulator. The fuel pump is adapted receive pump commands representative of a commanded fuel flow rate and is configured, in response to the pump commands, to discharge fuel at the commanded fuel flow rate. The burn flow fuel line is in fluid communication with the pump to receive a first portion of the fuel discharged therefrom. The servo flow fuel line is in fluid communication with the pump to receive a second portion of the fuel discharged therefrom. The servo regulator is mounted on the servo flow fuel line and configured to maintain fuel flow rate in the servo flow fuel line at a substantially constant fuel flow rate regardless of fuel flow rate in the burn flow fuel line.

摘要： A fuel management system (34) for a turbine engine having a metering valve (50) controlled by the input of an electronic computer (36) to a resolver (48). A head pressure sensor (67) responds to pressure differential across the fuel metering valve (50) to control a bypass valve (80) which allows a portion of the fuel available from a fuel supply conduit (58) to return to a fuel reservoir (28). A reference pressure controlled head bypass valve (80) utilizing pressures above (P.sub.1) and below (P.sub.2) a metering valve (50) as reference pressures during normal operation and a non-controlled reference pressure during shut-off to maintain a minimum fuel pressure required for control purposes during shut-off. The non-controlled pressure reference may be obtained as a pressure drop across a series (typically a pair) of small orifices or apertures. The non-controlled reference pressure is typically achieved as the intermediate pressure between a regulated (pcb) body pressure and the inlet fuel supply pressure (P.sub.1).

摘要： This invention relates to fuel controls for turbine types of power plants and to the means for resetting the idle speed and stator vanes from a single point contact. In one embodiment, fuel flow is reset by changing the hydraulic forces on the throttle valve and its control system which serves to provide a W.sub.f /P.sub.3 .times. P.sub.3 control function, where W.sub.f = fuel flow in pounds per hour and P.sub.3 = compressor discharge pressure in pounds per square inch absolute. The profile of the 3-D cam utilized to control the stator vanes is also utilized to set the droop schedule of the idle speed setting controlled by the fuel control.

摘要： For a fuel control for a turbine type of power plant a throttle valve servo piston combination including a servo control valve operated off of a multiplication lever system wherein said throttle valve servo piston combination is rotated resulting in a smaller unit and achieving a reduction in its size and that of the control valve and lever system. A gear secured to the rotatably supported mechanism is located in a judiciously selected position within the drain portion of the control and the maximum fuel flow limit changes the feedback system from a force balance one to a position one during maximum limiting.
