    • 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.
    • 提供了一种与燃气涡轮发动机(GTE)和燃料分配器系统结合使用的均流超控组件。 在一个实施例中,流量均衡超控组件包括壳体组件,燃料分配器(FD)阀,可远程致动的阀和控制器。 FD阀包括:(i)可滑动地设置在壳体组件内并可在默认位置和流动平衡位置之间移动的活塞,以及(ii)由活塞和壳体组件限定的控制室。 可远程致动的阀流体地联接到控制室,并被构造成选择性地调节其中的燃料压力。 控制器被配置为命令可远程致动的阀来调节控制室内的压力,使得活塞在GTE点火之后从默认位置移动到流动平衡位置。
