摘要： In one aspect, a pressure regulating valve assembly is provided. The valve assembly includes a housing having a fluid inlet and a fluid outlet, a sleeve positioned within the housing, and a spool at least partially positioned within the sleeve. The spool includes an outer surface having a shoulder, and the spool is configured to translate within the sleeve between a closed position and an open position. The valve assembly further includes a cap coupled to the sleeve and surrounding at least a portion of the spool, and the cap includes an inner surface with a flange extending therefrom. In the closed position the spool shoulder abuts against the cap flange to define a sealed metering edge. In the open position the spool shoulder is spaced from the cap flange to unseal the metering edge and define a metering window to facilitate fluid flow therethrough to the fluid outlet.

摘要： A system includes a flow inlet conduit and a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles. An equalization bypass valve (EBV) connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles. The EBV is connected to an equalization conduit (EC). A pressure equalization solenoid is connected to the EC to selectively connect a servo supply pressure conduit and/or a return pressure (PDF) conduit into fluid communication with the EC. An EBV rate limiting orifice (RLO) is connected in the PDF conduit. A bypass conduit branches from the PDF conduit on a first side of the EBV RLO and reconnects to the PDF conduit on a second side of the EBV RLO. An orifice bypass valve (OBV) is connected to the bypass conduit and acts to selectively bypass the EBV RLO.

摘要： A metering valve has a main inlet port and a spool movable, and a housing outlet port in a housing. The spool has a metering inlet orifice selectively aligned with the main inlet port, and a metering outlet orifice selectively aligned with the main outlet port. The main inlet port communicates with the metering inlet orifice, and the outlet port communicates with the metering outlet orifice to each provide a metering orifice. The main outlet port communicates downstream to a minimum pressure valve. The minimum pressure valve has a piston biased to a closed position by a spring force, and a line downstream of the main outlet port acting against a face of the piston in opposition to the spring force to ensure a minimum pressure moving downstream past the piston to a use. A fuel system is also disclosed.

摘要： A filter assembly for a fluid flow system includes a filter housing, a housing inlet to allow the fluid flow into the filter housing and a housing outlet to allow the fluid flow to exit the filter housing. A filter element is located in the filter housing to collect contaminants from the fluid flow. A pressure sensor is located to measure a pressure drop across the filter element. The pressure sensor includes at least one sense line extending into an interior volume of the filter housing. A method of monitoring a filter assembly for a fluid flow system includes positioning a pressure sensor at a filter assembly, extending at least one sense line from the pressure sensor into an internal volume of a filter housing of the filter assembly, and measuring a pressure drop across a filter element of the filter assembly via the pressure sensor.

摘要： 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.
