  • Pilot valve, method of using, and fluid system equipped therewith
    Patent number: 8689895
    Abstract: A pilot valve assembly for regulating the output of a first pressure source relative to a second pressure source, a fluid system equipped with the valve assembly, and a method of operating the valve assembly. The valve assembly includes a valve body with inlet and outlet ports and first and second sensing ports. The first and second sensing ports are adapted to sense, respectively, the fluid pressures of the first and second pressure sources. The inlet port is adapted for fluidically connecting to the first pressure source. The valve assembly defines a flow path between the inlet and outlet ports, and has components for allowing fluid flow from the inlet port, through the flow path, and to the outlet port only if the fluid pressure of the first pressure source exceeds the fluid pressure of the second pressure source by a differential by the flow-allowing components.
