发明名称 Dual-supply fluid distribution system and method of supplying fluid
摘要 A dual-supply fluid distribution system includes a first pump having an inlet and an outlet. The first pump is configured to supply a first fluid flow. A second pump has an inlet and an outlet, and is configured to supply a second fluid flow. A check valve is coupled between the first and second pump outlets. The check valve is configured to combine the second fluid flow with the first fluid. A bypass valve is coupled to the outlet of the first pump. The bypass valve has an integral pilot valve and is configured to permit fluid flow from the pump outlets in excess of the fluid demand to recirculate back to the first and second pump inlets. The bypass valve and integral pilot valve are configured to cause the check valve to open when the flow of fluid through the bypass valve is below a threshold amount.
