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) to apportion flow from the flow inlet conduit to the secondary conduit. A pressure equalization solenoid (PES) is connected to the EC to selectively connect at least one of a servo supply pressure (PFA) conduit or return pressure (PDF) conduit into fluid communication with the EC. A relief management valve (RMV) is connected in the PDF conduit.

摘要： 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.

摘要： 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.
