Patent number: 11674444Abstract: 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.Type: GrantFiled: March 30, 2021Date of Patent: June 13, 2023Assignee: Hamilton Sundstrand CorporationInventors: Charles E.

Patent number: 11255454Abstract: A fluid valve use in a turbomachine in a high temperature location includes a fluid inlet, a fluid outlet, a fluid circuit defined between the fluid inlet and the fluid outlet, and a solenoid including a solenoid casing. The solenoid is disposed between the fluid inlet and fluid outlet. The solenoid is configured to move a valve member between a closed position, at least one partially open position (e.g., any number of suitable positions), and a fully open position to selectively meter fluid flow through the fluid circuit. The fluid valve can include a valve casing, wherein the solenoid and valve member are disposed in the valve casing.Type: GrantFiled: November 25, 2019Date of Patent: February 22, 2022Assignee: Delavan Inc.Inventors: Daniel Edward Bleeker, Francis P.
