    摘要： Air Turbine Starters (ATSs) having oil feed shutoff valves are provided, as are gas turbine engines including ATSs. In one embodiment, the ATS includes an ATS housing assembly containing a sump chamber, an oil inlet, and a valve cavity. A rejected oil return passage is further formed in the ATS housing assembly and fluidly coupled to the valve cavity. An oil feed shutoff valve is positioned in the valve cavity and contains a valve element movable between open and closed positions. In the open position, the valve element permits oil flow from the oil inlet, through the valve cavity, and into the sump chamber. In the closed position, valve element blocks oil flow from the oil inlet into the sump chamber, while redirecting the oil flow into rejected oil return passage to reduce the loss of engine oil through the ATS in the event of an ATS housing breach.

    摘要翻译： 提供具有供油截止阀的空气涡轮起动器（ATS），以及包括ATS的燃气涡轮发动机。 在一个实施例中，ATS包括包含贮槽室，进油口和阀腔的ATS壳体组件。 在ATS壳体组件中进一步形成排斥回油通道并且流体地联接到阀腔。 供油截止阀位于阀腔中，并且包含可在打开和关闭位置之间移动的阀元件。 在打开位置，阀元件允许油从油入口通过阀腔进入油槽腔。 在关闭位置，阀元件阻止从油入口进入油底壳室的油流，同时将油流重新定向到废油返回通道，以在ATS壳体泄漏的情况下通过ATS减少发动机油的损失。

    摘要： Outflow valve (OFV) assemblies including non-metallic frames and enhanced attachment features are provided. In embodiments, the OFV assembly includes a non-metallic frame to which at least one valve door is pivotally mounted. The non-metallic frame may, in turn, include a generally rectangular frame body, a central opening through the frame body, an outer peripheral flange extending around at least a portion of the frame body. Frame attachment interfaces are distributed or spaced around the outer peripheral flange of the non-metallic frame. The frame attachment interfaces include fastener openings and elevated platform regions, which project from an inboard side of the outer peripheral flange and through which the fastener openings extend. Base plates seat against the elevated platform regions. Fasteners engage the base plates and extend through the fastener openings to an outboard side of the outer peripheral flange to attach the OFV assembly to an aircraft fuselage.
