    • The present invention provides a fuel system for an engine including a water supply source for providing water and a fuel supply source for providing fuel. A centrifugal pump is fluidly connected to the water and fuel supply sources, respectively at water and fuel inputs. The pump receives the water and the fuel from the inputs and produces a homogeneous mixture without using other pumps or mixing devices. A metering device is arranged between the pump and one of the supply sources, preferably the water supply source, to produce the desired ratio of water and fuel. The speed of the pump is varied to deliver the desired total volume and pressure of fuel and water to the engine through the pump output. The water metering device may be closed to deliver only fuel to the engine during special conditions such as engine startup and rapid load dumps. Operation of the system is simplified because only one pump and metering device is used.
    • 本发明提供了一种用于发动机的燃料系统,其包括用于提供水的供水源和用于提供燃料的燃料供应源。 离心泵分别在水和燃料输入端分别与水和燃料供应源连接。 泵从输入接收水和燃料,并产生均匀的混合物,而不使用其他泵或混合装置。 计量装置布置在泵和供应源之一,优选地是供水源之间,以产生所需的水和燃料比。 泵的速度是变化的,以通过泵输出将燃料和水的所需总体积和压力提供给发动机。 在诸如发动机启动和快速卸载的特殊条件下,水计量装置可以关闭以仅向燃油输送燃料。 简化了系统的运行,因为只使用一个泵和计量装置。

    • A fluid scavenging system is provided for a lubrication system including a gas turbine engine having bearing compartments. A valve includes a housing with an outlet and a plurality of fluid inlets respectively in fluid communication with the bearing compartments. The valve includes a rotationally driven member arranged within the housing with the member having a plurality of ports arranged thereon each defining an arcuate slot. Each of the ports are selectively in fluid communication with one of the fluid inlets through the arcuate slot during rotation of the member for selectively permitting fluid flow between the opening of one of the fluid inlets through one of the corresponding ports in the member. A fluid pump is fluidly connected to the outlet for drawing fluid from each of the plurality of fluid compartments during fluid rotation of the member. The driven member rotates about an axis 360°, and preferably, the ports are respectively aligned with the fluid inlets for approximately at least 360° such that the pump does not run dry. The arcuate slots may overlap during a range of degrees such that more than one compartment is scavenged. The size of the arcuate slot and degrees through which the arcuate slot is in communication with its respective inlet determines the duration that a particular bearing compartment is scavenged and the volume of bearing fluid that may be removed from the compartment.
    • 提供了一种用于包括具有轴承隔室的燃气涡轮发动机的润滑系统的流体清除系统。 阀包括具有出口的壳体和分别与轴承隔室流体连通的多个流体入口。 阀包括布置在壳体内的旋转驱动构件,其中构件具有布置在其上的多个端口,每个端口限定弓形狭槽。 每个端口在构件的旋转期间选择性地通过弓形槽与一个流体入口流体连通,用于选择性地允许流体在通过构件中的相应端口之一的流体入口之间流动。 流体泵流体地连接到出口,用于在构件的流体旋转期间从多个流体隔室中的每一个抽出流体。 被驱动构件围绕360°旋转,优选地,端口分别与流体入口对准大约至少360°,使得泵不会干燥。 弧形槽可以在一定范围内重叠,使得多于一个隔室被清除。 弓形槽的尺寸和弧形槽与其相应的入口连通的程度确定特定的轴承隔室被清扫的持续时间和可以从隔间移除的轴承流体的体积。
