Abstract
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.
Claims23
A system comprising:
- a flow inlet conduit;
- a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles;
- an equalization bypass valve (EBV) that connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles, wherein 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) connected to the EC to selectively connect at least one of a servo supply pressure (PFA) conduit or a return pressure (PDF) conduit into fluid communication with the EC;
- and
- a relief management valve (RMV) connected in the PDF conduit, wherein the RMV is configured to at least one of (i) increase flow through PDF conduit as the difference between PFA and PDF pressure is increased, or (ii) reduce flow through PDF conduit when the difference between PFA and PDF pressure is decreased.
A system comprising:
- a flow inlet conduit;
- a primary conduit that branches from the flow inlet conduit for delivering flow to a set of primary nozzles;
- an equalization bypass valve (EBV) that connects between the flow inlet conduit and a secondary conduit for delivering flow to a set of secondary nozzles, wherein the primary conduit branches from the flow inlet conduit upstream from the EBV, wherein 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) connected to the EC to selectively connect at least one of a servo supply pressure (PFA) conduit or a return pressure (PDF) conduit into fluid communication with the EC;
- and
- a relief management valve (RMV) connected in the PDF conduit.
