Abstract: A transfer valve includes a spool comprising a first circumferential flow channel at a first axial position of the spool and a second circumferential flow channel at a second axial position of the spool. The first circumferential flow channel and the second circumferential flow channel have different circumferential positions and are defined only partially circumferentially, and a sleeve disposed over the spool. The sleeve includes at least three flow windows defined through the sleeve at an axial position of the sleeve, each flow window having different circumferential positions on the sleeve. The spool is configured to translate within the sleeve between a first position and a second position. The first circumferential flow channel of the spool is configured to fluidly connect a first plurality of the at least three windows in the first position, and the second circumferential flow channel is configured to connect a second plurality of the at least three windows in the second position, wherein the first plurality of windows is different by at least one window from the second plurality of windows.

Abstract: A flexure includes a flexure body with an inner ring defining a main axis and an outer ring extending about the inner ring that is outboard of the inner ring with respect to the main axis. One or more flexure members having respective lengths that are greater than a radial offset distance defined between the inner ring and the outer ring connects the inner ring to the outer ring. A valve includes a valve member connected to a valve body by the flexure.

Abstract: A fuel system for a turbomachine includes a minimum pressure and shutoff valve (MPSOV) disposed between a fuel source and a fuel nozzle of a fuel system and configured to move between an opened position wherein fuel can flow to the fuel nozzle, and a closed position wherein fuel is prevented from flowing to the fuel nozzle, and a shutdown signal valve (SDSV) operatively connected to the MPSOV and configured to selectively supply a shutdown pressure to the MPSOV in a shutdown state such that the shutdown pressure forces the MPSOV to the closed position.

Abstract: 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.
