摘要： A fuel flow dividing ecology valve (35, 59) selectively conveys fuel from a fuel source (31) to at least a secondary gas turbine engine intake manifold (25) during engine operation and withdraws fuel therefrom upon cessation of engine operation. The valve includes a flow dividing valve portion (41) having an inlet (65) coupled to the fuel source and an outlet (67) coupled to the secondary manifold. The flow dividing valve portion transitions from a fuel flow blocking condition to a condition in which fuel may flow from the source to the manifold solely in response to the fuel pressure differential between the inlet and the outlet. The valve also includes an ecology valve portion (43) controlled solely by the fuel pressure differential between the dividing valve portion inlet and outlet for withdrawing fuel from the secondary engine intake manifold when the engine is de-energized thereby purging the manifold of fuel, and returning withdrawn fuel to the manifold during subsequent engine operation. In one form, fuel is conveyed from the fuel source exclusively to the secondary gas turbine engine intake manifold during engine operation and withdrawn exclusively therefrom upon cessation of engine operation. In another form, fuel from the fuel source is conveyed to both a primary (23) and a secondary (25) intake manifold during engine operation, and withdrawn from both manifolds upon cessation of engine operation. In either form, the ecology valve portion is controlled solely by the fuel pressure differential between the fuel source and the flow restricting inlet and includes a housing with a piston disposed therein for movement between first and second extreme positions. The piston defines, in conjunction with the housing, a variable volume chamber for withdrawing fuel from the engine intake manifolds when the engine is de-energized and the piston moves from the first extreme position toward the second extreme position thereby purging the manifolds of fuel.

摘要： A flow equalizing override assembly is provided for use in conjunction with a gas turbine engine (GTE) and a fuel divider system. In one embodiment, the flow equalizing override assembly includes a housing assembly, a fuel divider (FD) valve, a remotely-actuatable valve, and a controller. The FD valve includes: (i) a piston slidably disposed within the housing assembly and movable between a default position and a flow equalizing position, and (ii) a control chamber defined by the piston and the housing assembly. The remotely-actuatable valve is fluidly coupled to the control chamber and is configured to selectively adjust the fuel pressure therein. The controller is configured to command the remotely-actuatable valve to adjust the pressure within the control chamber such that the piston moves from the default position to the flow equalizing position after ignition of the GTE.

摘要： A gas turbine engine fuel control system is provided that includes a fuel metering valve and a thrust control valve. The fuel metering valve includes a metering valve inlet and a metering valve outlet. The metering valve inlet is adapted to receive a flow of fuel, and is configured to control the flow of fuel through the metering valve outlet. The thrust control valve is adapted to receive thrust control valve override signals and is configured, in response thereto, to move from a first position, in which flow from the metering valve is not impacted, and a second position, in which flow from the metering valve is blocked while flow through a fixed-area orifice is allowed.

摘要： An ecology valve (EV) fuel return system is provided. In one embodiment, the EV fuel return system includes a housing assembly having a fuel return outlet and a first manifold inlet. The fuel return outlet is fluidly coupled to a fuel supply system, and the first manifold inlet is fluidly coupled to a first manifold of a gas turbine engine (GTE). An ecology valve is disposed in the housing assembly and fluidly coupled to the fuel return outlet and to the first manifold inlet. A fuel routing assembly is fluidly coupled between the first manifold inlet, the fuel return outlet, and the ecology valve. The fuel routing assembly routes fuel: (i) from the first manifold inlet to the ecology valve when the GTE is in a shut-down mode, and (ii) from the ecology valve to the fuel return outlet when the GTE is in an engine start mode.
