Abstract: A system can include a first controllable valve, a second controllable valve, a transfer valve, and a transfer control system. The first controllable valve can be configured to output a control pressure on one or more first pressure control lines. The second controllable valve can be configured to output a control pressure on one or more second pressure control lines. The transfer valve can be in fluid communication with the first controllable valve and the second controllable valve. The transfer valve can be configured to move between a first position, a second position, and a third position.

Abstract: A pressure actuated switching valve includes a first valve chamber including a first chamber portion. The first chamber portion has a first inner diameter, a second chamber portion having a second inner diameter that is greater than the first inner diameter, a third chamber portion having a third inner diameter that is greater than the first inner diameter, a fourth chamber portion having a fourth inner diameter that is greater than first inner diameter, and a valve member. The valve member includes a first section having a first outer diameter that is greater than the first inner diameter. A second section of the valve member has a second outer diameter that is closely matched to the third inner diameter. A third section of the valve member is arranged has a third outer diameter that is greater than the first outer diameter.

Abstract: A fiber bundle cartridge for a fiber membrane degassing system includes an inner sleeve including one or more perforations and a fiber bundle positioned radially outward from the inner sleeve. The fiber bundle has an annular shape defining a central bundle axis. The perforations of the inner sleeve define a plurality of inlets and/or outlets facing radially with respect to the central bundle axis. A fiber membrane degassing system includes a housing defining a cylindrical volume having at least one inlet and at least one outlet. The system includes at least one fiber within the cylindrical volume, where fluid flowing through the cylindrical volume from the at least one inlet to the at least one outlet flows perpendicular to a longitudinal dimension of the fiber. A method of degassing a liquid includes directing a liquid volume through a fiber bundle in a direction radial to a longitudinally extending bundle axis.

Abstract: A fluid metering valve includes a flow circuit defined by the valve and a valve member disposed in the flow circuit, the valve member having a sealing portion and configured to be moved by a solenoid between a closed position and one or more open positions. The valve includes a seat member defining one or more fluid outlets, the seat member configured to receive the sealing portion in the closed position to seal the fluid outlets, and an internal porting path defined through the sealing portion that is configured to fluidly connect a downstream side of the sealing portion with an upstream portion of the flow circuit in the closed position to reduce the effective pressure area of the valve member.

Abstract: A bleed valve for a gas turbine engine compressor has a valve body and a flapper. The valve body defines a flow path and includes a flapper seat. The flow path extends through the valve body. The flapper is pivotally connected to the valve body and is movable between a closed position and an open position. In the closed position the flapper seats against the flapper seat and blocks the flow path. In the open position the flapper is angled towards the valve body inlet such that fluid moving through the valve body exerts force on the flapper, urging the flapper towards the closed position.
Abstract translation: 用于燃气涡轮发动机压缩机的放气阀具有阀体和挡板。 阀体限定流路并包括挡板座。 流路延伸穿过阀体。 挡板枢转地连接到阀体并且可以在关闭位置和打开位置之间移动。 在关闭位置，挡板抵靠挡板座并阻挡流路。 在打开位置，挡板朝向阀体入口成角度，使得流过阀体的流体对挡板施加力，将挡板推向关闭位置。
