摘要： A fuel flow system (10) for a gas turbine includes a first pump (20), a main fuel flow path (12c) and a second pump (20). The first pump (20) is connected to an actuator and a metering valve (26). The main fuel flow path (12c) is formed between the first pump (20) and the metering valve (26). The second pump (30) is connected to the main fuel flow path (12c) and supplements the fuel flow from the first pump (20) under certain conditions. The second pump (30) and first pump (20) are in parallel.

摘要： A pressure switch (15) includes a pressure chamber (29) and a moving disc (28). The moving disc (28) is moveable in response to a pressure in the pressure chamber (19) to cause contact between a moveable contact (42,44) and a fixed contact (40,46). An orifice (27) communicates a fluid pressure into the pressure chamber (29). The orifice (27) provides a tortuous path for a fluid flow to reach the pressure chamber (29). An oil supply system and a generator are also disclosed.

摘要： A fuel system (14) for a gas turbine engine (12) includes an engine fuel manifold (24), a hydraulic actuator (38), and a drain piston assembly (36). The hydraulic actuator (38) actuates in response to a change in pressures within the hydraulic actuator (38). The drain piston assembly (36) is fluidically connected to both the hydraulic actuator (38) and the engine fuel manifold (24). The drain piston assembly (36) receives fuel from the engine fuel manifold (24) and sends fuel to the hydraulic actuator (38) during engine shut down.

摘要： A reservoir (26) includes first and second chambers (38, 36), and a piston (42) having first and second ends (48, 44) disposed in the first and second chambers (38, 36), respectively. The first and second ends (48, 44) isolate a first area (52, 112) from a second area (50, 46) within the first and second chambers (38, 36). The first area (52) of the first chamber (38) is in fluid communication with a high pressure fluid source and the second area (50) of the first chamber (38) is in fluid communication with a low pressure fluid source. An orifice (56) is formed in the first end (48) and is configured to allow fluid communication between the first and second areas (52, 50) of the first chamber (38). A pumping system (10) and an aircraft are also disclosed.

摘要： A fuel flow system (10) for a gas turbine engine includes a first pump (20), a second pump (38), a bypass loop (12e), an integrating bypass valve (28) and a pilot valve (30). The first pump (20) connects to an actuator (48) and a metering valve (24). The second pump (38) connects to the metering valve (24) and is arranged in parallel with the first pump (20). The bypass loop (12c) recycles fuel flow from the first pump (20) and the second pump (38) to inlets of the first pump (20) and second pump (38). Integrating bypass valve (28) includes first and second windows (28a,28b). The first window (28a) regulates fuel from the first pump (20) through the bypass loop (12e) and the second window (28b) regulates fuel from the second pump (38) through the bypass loop (12e). The pilot valve (30) controls the size of the first and second windows (28a,28b).
