摘要： A method of metering fuel with a fuel valve (10) includes arranging a spool (12) within a sleeve (14) along an axis (A), wherein the spool (12) includes four seal lands (22A-22D). The sleeve includes a fuel inlet aperture (S34), a fuel outlet aperture (S36), and a shutoff port (S38). A first cavity (C1) and a second cavity (C2) are defined between the spool (12), the sleeve (14), and subsets of the seal lands (22A-22D). The fuel inlet aperture (S34) and the fuel outlet aperture (S36) abut one such cavity (C1,C2). Sliding the spool (12) along the axis (A) results in the fuel outlet aperture (S36) extending longitudinally beyond the second seal land (22B) in the upstream direction.

摘要： A fluid flow system (10) for a gas turbine engine (12) provides combustion fuel to a main pump (48) and an actuator pump (50) significantly reducing heat generation at low flow demand, while regulating actuator flow temperature at high flow demand. Fuel flow from the actuator pump (50) in excess of the actuators (60) needs is directed through an actuator minimum pressure valve (58) and into a thermal bypass valve (TBV) (54). Depending upon the temperature of the fuel, the TBV (54) determines the path of the excess actuator pump fluid flow. The TBV (54) divides the fuel flow between being recirculated to the actuator pump inlet (62) and the main pump output flow path (66) to the engine fuel input conduit (68). The engine actuators (60) are thereby assured of receiving flow which preclude freezing of water entrained in the fuel. When there is minimal concern with the possibility of freezing water entrained in the fuel, the TBV (54) passes a greater percentage of fuel through to join together in the engine fuel input conduit (68).

摘要翻译：用于燃气涡轮发动机（12）的流体流动系统（10）向主泵（48）和致动器泵（50）提供燃料燃料，以显着降低在低流量需求下的发热，同时在高流量需求下调节致动器流量温度。来自致动器泵（50）的超过致动器（60）需要的燃料流被引导通过致动器最小压力阀（58）并进入热旁通阀（TBV）（54）。取决于燃料的温度，TBV（54）确定过量的致动器泵流体流动的路径。 TBV（54）将再循环到致动器泵入口（62）和主泵输出流路（66）之间的燃料流分配到发动机燃料输入管道（68）。因此，发动机致动器（60）确保接收流动，排除了夹带在燃料中的水的冻结。当对燃料中夹带的冷冻水的可能性至关重要时，TBV（54）通过较大百分比的燃料通过以将其连接在发动机燃料输入管道（68）中。

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 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).
