摘要： A system and method provide dual level pressurization control of a fuel supply system based on whether fuel is being supplied to one or more secondary fuel loads. Fuel pump discharge backpressure is maintained above either a first minimum pressure value or a lower second minimum pressure value by determining whether fuel is being supplied to one or more secondary fuel loads. The fuel pump discharge pressure is maintained above the first minimum pressure value if it is determined that fuel is being supplied to the one or more secondary loads. The fuel pump discharge backpressure is maintained above the lower second minimum pressure value if it is determined that fuel is not being supplied to the one or more secondary loads.

摘要： A system allows a user to manually manipulate fuel flow to a gas turbine engine during a loss of power to the fuel supply system fuel metering unit. The fuel metering unit includes a fuel metering valve, a metering valve actuator, a fail-fixed valve, a flow increase valve, and a flow decrease valve. The fuel metering unit is configured such that, upon electrical power interruption to the metering valve actuator, the fail-fixed valve shifts and provides a hydraulic lock on the fuel metering valve, to thereby maintain its position. The flow increase and flow decrease valves are powered from a power source that is independent of that used to power the fuel metering unit and, when appropriately energized will allow movement of the fuel metering valve.

摘要： A flow prioritizing system includes a regulating valve and a flow prioritizing valve. The regulating valve receives a first portion of the fluid supplied from a fuel supply pump, and is responsive to a control pressure to selectively allow or prohibit flow to secondary loads. The flow prioritizing control valve is responsive to fluid pressure representative of delivery pump discharge pressure to control the control pressure to which the regulating valve is responsive.

摘要： A fuel control system for supplying metered quantities of fuel from a fuel supply (11), through a fuel pump (13), a metering valve (15) and a pressurizing valve (17) to a plurality of engine fuel manifolds (31a, 31b, 33) includes an ecology valve (43) for withdrawing fuel from the engine fuel manifolds (31a, 31b, 33) during cessation of engine operation and for returning fuel to the engine fuel manifolds (31a, 31b, 33) to be burned during normal engine operation. The ecology valve (43) includes a valve housing (44) having a plurality of ecology ports (50, 52, 54) adapted to be coupled to corresponding ones of the engine fuel manifolds (31a, 31b, 33) and a control port (46) adapted to be connected to a corresponding control port (45) of the fuel pressurizing valve (17). A movable piston (63) is supported within the valve housing (44) for reciprocable motion and divides the interior of the valve housing (44) into a variable volume control chamber (71) coupled to the control port (46) and a variable volume fuel reservoir (55) which is selectively coupled to and uncoupled from the ecology ports (50, 52, 54) by the piston (63). Fuel is withdrawn from the manifolds (31a, 31b, 33) seriatim. A fuel flow dividing arrangement is located intermediate the pressurizing valve (17) and the engine fuel manifolds (31a, 31b, 33) for distributing appropriately fuel flow among the manifolds and includes a concatenated pair of two-way splitter valves (39, 41) comprising a first splitter valve (39) distributing the fuel flow between an atomizer nozzle manifold (31b) and the remaining manifolds (31a, 33), and a second splitter valve (41) distributing down stream fuel flow from the first splitter valve (39) between upper and lower manifolds (31, 33).

摘要： A combination pressurizing valve (27) and fuel flow divider for a gas turbine is operable in three different fuel distribution modes utilizing three windows which are successively opened to control the flow distribution to the engine atomizing or start-up nozzles (23) and engine air blast or running nozzles (25) respectively by way of two fixed orifices (51, 55) in a way that satisfies the start-up flow distribution favoring the atomizing nozzles (23) as well as the need for balanced flow distribution between the different types of engine nozzles after a successful start. The first window position corresponds to an engine ignition mode and includes a range of intermediate valve spool (33, 133) positions where one outlet port (57) is open and the other outlet port (67) receives a restricted flow of fuel. The second window position includes a range of valve spool (33, 133) positions where the one outlet port (57) is open and the other outlet port (67) is open to receive a flow of fuel greater than the restricted flow. The third window position corresponds to a full power engine condition and includes a range of valve spool (33, 133) positions including the another extreme position where the one outlet port (57) is open and the other outlet port (67) is open to receive a still further increased flow of fuel.

摘要： A seal for preventing leakage of pressurized fluid along a flow path along an engagement plane between a first and second members. The seal has a cylindrical body with a first elastomeric ring located on an end and a second elastomeric ring located on a peripheral surface of the cylindrical body. The cylindrical body is located in a passage in the second member. A spring urges the first elastomeric ring into engagement with a face on the first member when the first and second members are joined together. Pressurized fluid which flows from a passage in the first member into the second passage in the second member acts on the cylindrical body to further urge the end into engagement with the first member to prevent fluid leakage along the engagement plane there between.

摘要： A fuel control system (10) for a gas turbine engine includes a main fuel inlet line (18), an auxiliary fuel inlet line (20) and an engine fuel outlet line (16). A first flow path extends from the main fuel inlet line (18) to the engine fuel outlet line (16) and a second flow path extends from the auxiliary fuel inlet line (20) to the engine fuel outlet line (16). A check valve (22) in the first flow path allows fuel flow through the first flow path in a direction from the main fuel inlet line (18) to the engine fuel outlet line (16) and substantially prevents fuel flow through the first flow path in a direction from the engine fuel outlet line (16) to the main fuel inlet line (18). The check valve (22) is shiftable between a first position connecting the auxiliary fuel inlet (20) to the engine fuel outlet (16) and a second position blocking the second flow path. Also a method of controlling fuel flow in a fuel control system of a gas turbine engine.

摘要： The present invention provides a relatively simple way to automatically turn on and off the fuel to a starter/generator cooling system during engine start. The present invention takes advantage of a fuel pressure rise provided by an engine fuel boost pump during the period from engine start to engine idle conditions. This pressure rise is used to stroke a shutoff valve in a fuel return to tank valve (FRTTV), which shuts off the starter generator cooling fuel flow. This shutoff occurs automatically with no other external input from, for example, an engine controller. A check valve is also included that prevents back flow through the FRTTV in the event of an engine start with no aircraft pumps running.
